Full textAbstract:
Mangroves provide multiple benefits for local communities’ livelihoods. However, in the Mahakam delta mangroves have declined considerably. This study examines the factors affecting households’ willingness to pay (WTP) for mangrove restoration in three villages in the Mahakam delta and determines whether a mangrove restoration project would be viable and should be implemented in the study area or not. The contingent valuation method was applied through a double-bound dichotomous choice format to estimate the WTP for mangrove restoration. The results showed that over 80% of perception of respondents considered the benefits of mangroves were essential that associated with their livelihoods. Local residents tended to be willing to pay more for mangrove restoration when they acknowledged the benefits of mangroves and when they felt that the sustainability of mangrove ecosystems was their responsibility. The benefits transfer method was also used to estimate the costs and benefits of an ongoing mangrove restoration project in the study area. The benefits provided by mangroves, as estimated based on households’ WTP, clearly outweighed the costs for the mangrove restoration project. We conclude that mangrove restoration should be implemented in the study area by increasing local communities’ awareness and responsibility to protect and manage the mangrove a sustainable.

Highlight Research Anthropogenic factors are the main cause of damage to mangrove ecosystems Restoration is a method for ecosystem restoration Restoration success is seen from the physical, chemical, and biological parameters Phytoplankton is a bioindicator of water quality The abundance of mangroves can explain the state of an ecosystem Abstract Mangrove ecosystems in Sine and Pancer Cengkrong had degraded due to land-use change and restoration has been carried out over a few year on the damaged location. This study was conducted to evaluate water quality of mangrove ecosystems at both locations based on physical, chemical and phytoplankton parameters as bioindicators. The evaluation of Cengkrong Mangrove was carried out at 4 different locations based on different periode of restoration, namely restoration of 2008-2009, 2013-2014, natural mangroves, and 2005 succession mangroves, whereas there was only one sampling site at Sine mangrove namely 1998-2008 restoration. The physico-chemical parameters measured include water temperature, air temperature, conductivity, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), salinity, nitrate, and orthophosphate. Phytoplankton data was used to measure, trophic diatom index (TDI) as an indicator of water nutrition status, and pollution tolerant value (%PTV) as an indicator of organic pollution. The results showed that the water quality at all the study locations met the Indonesian Ministry of Environment Regulation No 51/2004, except nitrate and phosphate. Based on the TDI index, mangrove in Sine, Cengkrong 2013-2014 restoration, and 2005 succession mangroves were categorized as hyper-eutrophic, natural Cengkrong mangroves were categorized as eutrophic, and 2008-2009 restored Cengkrong mangroves were categorized as meso-eutrophic. Based on the %PTV index, in the Sine mangrove, 2013-2014 Cengkrong restoration, and 2005 succession mangroves were classified as high levels of organic matter pollution, while in the Cengkrong 2008-2009 restoration and natural Cengkrong were classified as a moderate level of organic pollution.

Mangroves provide natural buffers between land and sea, protecting both coastal communities and nature as they attenuate waves and stabilize shorelines but also filter terrestrial runoff. Tropical mangroves are also biodiversity hotspots and provide other ecosystem services such as supporting fish and shellfish habitat, accommodating ecotourism and sequestering carbon. Nevertheless, mangrove coasts have become increasingly exposed to changing environmental conditions, a trend that has resulted in a declining mangrove cover on a global scale. At the protected Ramsar site of Lac Bay, Bonaire, large areas of mangroves have been subject to deterioration and tree mortality (Senger et al., 2021). Excessive sediment inputs from the land and mangrove growth have clogged existing creeks and reduced hydrodynamic circulation through the mangrove system. Resulting changes in sedimentation rates, submergence and water quality affect the survival of the inland mangroves in Lac Bay. The (re-)creation of suitable morphological and hydrodynamic conditions is key for mangrove restoration (Friess et al., 2019). This study investigates the potential of creek restoration to increase the hydrodynamic circulation in the mangroves of Lac Bay, thereby accommodating their survival.

"Mapping the Mangrove Forest Restoration Potential and Conservation Gaps in China Based on Random Forest Model."

Background and objective: The area of mangroves is gradually decreasing globally, and mangroves are already one of the most threatened ecosystems. Despite net growth in the mangrove areas in China, the restoration potential of mangroves is still insufficient. This study proposed the Random forest model as an excellent data mining method to map the restoration potential based on the predicted probability of mangrove habitat suitability.Methods: We demonstrated the vital environmental variables influencing habitat suitability. The de-cisive advantages of RFM were parsimonious (variables selection), cost-effective (us-ing existing open-source data), accurate (training AUC was 0.89, testing AUC was 0.91), highly efficient (fast-training speed); and its results had high explanatory power. Here, we first mapped the conservation gaps using the RFM.Results: The results showed that temperature was the most important environmental factor influencing the habitat suit-ability of mangroves. The northern limit of suitable areas was around 24°44' N. The theoretical suitable habitat area for mangrove was 196,566.6 ha (the highly suitable area was 32,551.4 ha, the medium suitable area was 164,015.2 ha). The potential area for mangrove restoration was 176,264 ha (Guangdong with 104215.4 ha, Guangxi with 65957.5 ha).Conclusion: We proposed 24 sites with conservation gaps for mangrove forests restoration and nine potential sites as examples for the further restoration plan. We took one example site with high restoration potential for further explanation: how the key environmental factors influence the habitat suitability and how to use the infor-mation to guide the restoration strategies. RFM can be used as a data mining algo-rithm for the utmost use of the presence-only ecological data, objectively evaluating the suitability of species distribution, and providing scientifically technical data for species restoration planning.

Mangroves have been converted and degraded for decades. Rates of loss have declined over the past decades, but achieving resilient coastlines requires both conservation and restoration. Here, we outline the challenges for the global restoration of mangroves and what actions could enhance restoration. Ambitious global targets for mangrove restoration, if successful, could deliver global benefits of carbon sequestration, fisheries production, biodiversity, and coastal protection. However, large-scale mangrove planting efforts have often failed, and smaller projects may not deliver landscape-scale benefits, even though they are more suited to community management. Solutions to achieving global targets include reducing risks of large projects and increasing the uptake and effectiveness of smaller projects. Sustainable mangrove restoration requires investment in capacity building in communities and institutions, and mechanisms to match restoration opportunities with prospective supporters and investors. Global reporting standards will support adaptive management and help fully understand and monitor the benefits of mangrove restoration.

Mangroves are plants that live on the coast and are affected by sea tides. Mangroves play an important role in estuary areas, namely the border between seawater and fresh water because they have ecological, economic and chemical functions to support the life of organisms. Mangrove ecosystems can experience threats from both natural and human factors. Human activities that cause damage to mangroves are due to a lack of public awareness regarding the importance of mangrove ecosystems for organisms. This is the condition that occurs in the mangrove ecosystem in Waai Village, therefore, it is necessary to restore the mangrove ecosystem. Mangrove ecosystem restoration uses one of the potential media, namely BESE-Element, which is a biodegradable material. Community service is carried out in collaboration with the Pattimura University Maritime Center and Wardenburg Ecology International. The community service activities were carried out for two days, 7-8 February 2023. The result of the activity was that mangrove ecosystem restoration was carried out in semi-enclosed areas using 10 BESE-Element. The types of mangrove species planted were Sonneratia alba, Rhizophora stylosa, and Ceriops tagal. Around BESE-Elements planted seedlings and mangrove propagules as a control for mangroves in BESE-Elements. This restoration activity seems to be applicable not only in Waai Village but also in other areas that have experienced degradation of the mangrove ecosystem.

Full textAbstract:
Mangrove ecosystems, amongst the most productive and biologically complex on Earth, are being degraded worldwide, and their widespread decline during the past decades has affected vital ecosystem services. Mangroves at Koggala lagoon on the southern coast of Sri Lanka have been degraded at an alarming rate due to agricultural practices, coastal zone development, and tourism activities. Most of the banks are heavily eroded due to boat and sea plane activities, and the mangrove ecosystem has been significantly damaged. Implementation of a scientific rehabilitation project was needed to restore this degraded mangrove ecosystem, and research was carried out to enrich the mangrove community by re-establishing mangroves on the eroded banks using corrosion-resistant plastic barrels. The sustainability of replanted mangroves was monitored under phase one and the re-establishment of ecological functions in the mangrove community was monitored under phase two. The accumulated biomass carbon during the period of two and half years was calculated by an allometric equation suggested for calculating biomass carbon of mangroves using the girth and height of individuals. The highest rate of girth increment was observed by the 24th month from establishment, whilst the growth rate declined between the 18th and the 30th months. During the study period, the average above-ground and below-ground biomass per barrel showed a linear increment. Our case study showed that the new method used for restoration is successful in establishing mangroves in sites with high erosion. This restoration technique was successful in coping with the situation in Koggala lagoon where previous restoration attempts were failures. Thus, we recommend this restoration method for sites facing the threat of severe erosion.

Mangroves provide multiple ecological functions such as connectors and balancers of land and sea ecosystems. The presence of mangroves in coastal areas is very important for reducing the impact of tsunamis and tidal flooding. The role of local communities in the form of community-based tourism models, in conserving mangrove forests has not been extensively studied. This study aims to fill the gap in evaluating local communities’ involvement, particularly under the tourism-based communities’ model, in conserving mangroves and, at the same time, gaining economic benefits. This study was conducted in the mangrove villages of “Patikang,” Citeureup Village, and Pandeglang Regency. This study applied mixed methods that combine both quantitative and qualitative approaches. Primary data were obtained directly from the local community through using questionnaires, interviews, and field observations. Secondary data collection was carried out through a literature review of mangrove conservation and community development in coastal areas. Our study found that local community-based tourism namely “Putri Gundul” played a very important role in increasing community awareness to conserve mangrove forests. The community has gained more knowledge on the biology of mangrove species and the ecology of mangroves for mangrove restoration. Furthermore, the involvement of local communities in mangrove conservation and restoration can increase the economy of communities by producing various products from mangroves.

Mangroves are essential for the environment and serve as a barrier. They are only found in the intertidal areas of rivers and estuaries, acting as nurseries for fish and other marine life with great ecological and monetary values. It also recycles nutrients and preserves the hydrological cycle and coast protection from storm surges. Although being a plant that can withstand high levels of salt, mangroves require a steady supply of fresh water to exist. Mangroves have been rapidly disappearing from the past many years, which have had detrimental effects on the ecosystem, climate, and society by reducing benefits including carbon sinking, coastal protection, and seafood production. Mangrove forest restoration is feasible and has already been attempted in a number of locations, but these initiatives have largely failed due to their fragmented nature. The current paper describes the results of a new initiative to identify and map the locations where mangroves can be restored, as well as to estimate the potential benefits from such restoration with reference to India. The present research is carried out with the following objectives: Mangrove loss and threats, as well as actions made to restore them. Evaluation of Gujarat and Indian mangroves. Stressing the need of rules and regulations for the rehabilitation of mangroves. Repercussions for management and policy recommendations.

_ This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 207725, “Mangrove Restoration and Conservation as a Carbon Offset Option: a Case Study in the Niger Delta Region,” by Gustavo C.D. Estrada, Jason Sali, and Patrizio Piras, Eni, et al. The paper has not been peer reviewed. _ Mangroves have gained attention as a carbon offset option because of their high carbon-storage capacity and diverse social and environmental benefits. Carbon stock in mangroves is approximately four times higher than in terrestrial forests and contributes to almost 10% of the global terrestrial carbon pool. In 2017, the Nigerian Agip Oil Company (NAOC) launched an initiative to restore mangroves to promote social and biodiversity benefits while contributing to offsetting its greenhouse-gas (GHG) emissions. The complete paper details the methodology and results of this initiative. Introduction Mangroves are coastal ecosystems mainly composed of typical tree and shrub plant species possessing adaptations to unstable, low-oxygen soil; high-salinity water; and frequent submersion. Fauna equally adapted to the unique environmental conditions observed in the mangroves also are considered part of the ecosystem. Mangrove forests are recognized globally to be of extreme ecological, economic, social, and cultural importance because of the variety of goods and services they provide. Some of these include the protection of the coastline from the energy of the winds and waves and conservation of fishing and biodiversity in coastal and adjacent estuarine waters. The literature suggests that more than 812,000 ha of mangrove areas, spread over 106 countries or territories, show potential for restoration. Furthermore, mangroves have been lost globally at a rate of 1–2%/year, which may account for an annual emission of approximately 0.09–0.45 GtCO2eq/year that could be avoided through conservation. Because the dispersion of mangroves propagules (seeds that have germinated while attached to the mother plant) is driven by ocean and estuarine currents, natural recolonization can occur and mangroves recover successfully by secondary succession during a period of 10–15 years if conditions are ideal. However, ecosystem function may take more than a century to be fully reinstated. Understanding the autoecology, hydrological patterns, and factors impairing natural regeneration is key for a successful restoration project. Several examples exist of restoration programs that were unsuccessful for, among other problems, having failed to acquire these key prerestoration data. During the last 10–15 years, a community-based ecological mangrove restoration effort has emerged based on the recognition that ecological science is not enough to assure successful restoration of mangroves and that social and economic issues must also be integrated.

Mumbai is the economic capital and the most densely urbanized coastal city of India. Environmental strain caused by rapid development of the city is studied with focus on one aspect of Mumbaiâ s environment, the mangrove ecology, which has been threatened by urbanization ever since the city began to evolve. The development authority of the city proposes a regional plan to guide future growth. An addendum to this regional plan is part of this thesis. The process of developing a mangrove mitigation plan is discussed in this paper. The paper analyzes the potential mangrove stand, which can be restored, and why they need to be restored.
This thesis recommends mangrove conservation and restoration policies for Mumbai, based on the process of data collection, data structuring, comparative analysis and development of implementation strategies.
A study of Mangrove management policies implemented in other countries and coastal cities supports the mangrove management strategies suggested for the city of Mumbai. Future land development proposed by the development authority of Mumbai has been analyzed to identify probable impacts on mangrove ecology and to highlight mangrove mitigation sites. These sites offer a platform for active mangrove management that will provide important environmental services to Mumbai in the future.Master of Landscape Architecture

Full textAbstract:
Les mangroves sont des socio-écosystèmes côtiers uniques qui se situent au niveau des zones tropicales et subtropicales mondiales. Elles subissent des dégradations anthropiques et naturelles compromettant à la fois leurs fonctionnalités écologiques et leurs nombreuses contributions aux sociétés humaines. Face à ce constat, de nombreux projets de restauration des mangroves ont vu le jour. Cependant, sur le long terme, un grand nombre de ces initiatives a échoué, mettant en lumière un manque de compréhension de l'écosystème et de sa relation avec les sociétés humaines. Dans ce cadre, cette thèse a pour objectif principal de répondre à la problématique suivante : Comment améliorer l'efficacité des projets de restauration écologique des mangroves ? Trois objectifs de recherche ont émergé pour y répondre : (i) évaluer l'efficacité des projets de restauration pour la nature et la société (ii) identifier les lacunes conduisant aux mauvaises pratiques, et enfin (ii) proposer des solutions pour améliorer les projets. Pour atteindre ces objectifs, une analyse géographique des projets de restauration à l'échelle mondiale a été entreprise, examinant chacune des grandes phases des projets : la conception, la mise en œuvre des mesures de restauration et le suivi-évaluation. Dans la phase de conception, une des lacunes majeures identifiées est le manque de méthodes d'évaluation standardisées de l'état pré restauration du site accessibles aux gestionnaires. Afin de répondre à ce besoin, les bases de l'outil d'évaluation rapide RAM MANGROVES ont été développées. Une analyse bibliographique, couplée à des entretiens semi-directifs avec des experts et étayée d'un test sur le terrain a permis d'aboutir à une méthode constituée de 16 descripteurs écologiques et socio-économiques, ainsi que d'un protocole de terrain standardisé. Dans la phase de mise en œuvre, un état de l'art des mesures de restauration et une synthèse des recommandations scientifiques afin de les améliorer ont été réalisés. Pour ce faire, une analyse comparative des projets de restauration à l'échelle mondiale et l'étude approfondie d'un cas particulier aux Philippines ont été réalisés. Ces travaux ont mis en évidence l'importance cruciale d'une approche systémique intégrant des aspects écologiques, sociaux et économiques pour maximiser les chances de réussite d'un projet de restauration. Ils ont également confirmé un point essentiel : la réhabilitation des conditions propices au développement des mangroves doit être pensée en première intention, la replantation ne doit être envisagée que si les conditions environnementales favorables au maintien et au développement de la mangrove ont déjà été réhabilitées, ou n'ont pas été dégradées. Ce travail a également mis en lumière que la plupart des recommandations scientifiques ne sont pas respectées dans beaucoup de projets de restauration des mangroves. Enfin, dans la phase de suivi-évaluation, un manque important d'évaluation des projets a été identifié. Pour encourager les porteurs de projets à réaliser cette étape cruciale, une approche par télédétection à haute résolution est proposée. Cette approche a été utilisée afin d'évaluer l'évolution du couvert végétal de six sites de restauration au Costa Rica, au Sénégal, au Bénin et aux Philippines. Cette analyse utilise des images Landsat et Sentinel. Une analyse à multiples échelles spatiales et temporelles a été réalisée afin de garantir la robustesse des interprétations. Les résultats ont révélé une grande précision de la cartographie, avec un indice de Kappa moyen de 0,95, confirmant la fiabilité de cette approche. En synthèse, l'efficacité des projets de restauration des mangroves se révèle étroitement liée à la qualité de la conception du projet, à la pertinence des mesures de restauration sélectionnées, à l'engagement actif des communautés locales et à l'utilisation d'outil de suivi appropriéMangroves represent unique coastal social-ecosystems situated in tropical and subtropical regions worldwide. They endure both anthropogenic and natural degradations, compromising their ecological functionalities and their numerous contributions to human societies. In response to this situation, a multitude of mangrove restoration projects have been initiated. However, in the long term, a significant portion of these initiatives has failed, highlighting a lack of understanding of the ecosystem and its relationship with human societies. Within this context, this thesis primarily aims to address the following question: How can the effectiveness of mangrove ecological restoration projects be improved? Three research objectives have emerged in response: (i) to assess the restoration projects' effectiveness for nature and society, (ii) to identify gaps leading to poor practices, and finally, (iii) to propose solutions to enhance the projects. To achieve these objectives, a geographic analysis of restoration projects on a global scale was undertaken, examining each of the projects' major phases: design, implementation of restoration measures, and monitoring-evaluation. In the design phase, one of the major identified gaps is the lack of standardized pre-restoration site assessment methods accessible to managers. To address this need, the foundations of the Rapid Assessment Method for Mangroves (RAM MANGROVES) tool were developed. A bibliographic analysis, coupled with semi-structured interviews with experts and supported by a field test, led to a method consisting of 16 ecological and socio-economic descriptors, as well as a standardized field protocol.During the implementation phase, a state of the art of restoration measures and a synthesis of scientific recommendations for their improvement were carried out. This involved a comparative analysis of global restoration projects and an in-depth study of a particular case in the Philippines. These efforts highlighted the crucial importance of a systemic approach integrating ecological, social, and economic aspects to maximize the chances of a restoration project's success. They also confirmed a key point: rehabilitation of conditions conducive to mangrove development should be considered a priority, with replanting only considered if the environmental conditions favourable to the maintenance and development of mangroves have been rehabilitated or were not degraded. This work also illuminated that most scientific recommendations are not adhered to in many mangrove restoration projects.Finally, in the monitoring-evaluation phase, a significant lack of project evaluation was identified. To encourage project holders to undertake this crucial step, a high-resolution remote sensing approach is proposed. This approach was used to evaluate the evolution of the vegetation cover of six restoration sites in Costa Rica, Senegal, Benin, and the Philippines. This analysis utilizes Landsat and Sentinel images. An analysis at multiple spatial and temporal scales was conducted to ensure the robustness of the interpretations. The results revealed a high accuracy of the mapping, with an average Kappa index of 0.95, confirming the reliability of this approach.In summary, the effectiveness of mangrove restoration projects is closely linked to the quality of project design, the relevance of selected restoration measures, the active engagement of local communities, and the use of appropriate monitoring tools

Full textAbstract:
As communities and managers become aware of the long-term impacts of mangrove loss, estimated at 1-2% per year, interest in sediment erosion and mangrove rehabilitation has increased substantially. In this thesis project I 1) examine erosion rates within coastal fringing Rhizophora mangle ecosystems following mangrove clearing and compare these rates to accretion rates in intact mangroves; and 2) investigate the abiotic factors influencing mangrove seedling survival and regeneration of naturally colonizing R. mangle, in historic mangrove habitat after anthropogenic clearing.
Differences in erosion were compared between patches of open-coast intact and anthropogenically cleared R. mangle to quantify the sediment trapping function provided by mangroves and its loss following clearing over a 24 month period. Growth rates of mangrove seedlings in intact forest were compared to seedlings in cleared areas. Seedling growth indicators were measured on 100 seedlings at five sites (50 in the intact and 50 in the cleared areas). To examine the limiting factors on seedling growth rates, nutrient addition and wave protection treatments were applied to seedlings in three disturbed areas.
Sites within intact mangroves had sediment accretion (M= +3.83 mm) while areas cleared of mangroves had sediment erosion (M= -7.30 mm). Seedling growth (height) over the 2 year study period significantly differed between intact mangrove (M = 15.6 cm) and cleared (M = 10.24 cm) areas. Seedling mortality from the cleared areas (31%) differed from the intact areas (13%). Average seedling growth (height) was: greater with both nutrient/wave (M = 18.4 cm) and nutrient (M = 17.65 cm) treatments compared to controls (M = 10.8 cm), which suggests that providing nutrients and/or wave protection result in growth outputs comparable to seedlings found in intact mangroves.
This study may prove to be useful in identifying areas that are most vulnerable to erosion following mangrove removal and ideal location of restoration following mangrove removal. Areas cleared of mangroves can lead to intensified erosion in areas where fringing reefs are not continuous. When managers are determining areas to focus resources for restoration, focusing on areas with nutrient rich habitat may result in higher survival rates and growth outputs.

This study aimed to compare the development of crab and tree communities of two restored mangrove areas, one planted with Rhizophora mangle and the other naturally recovered, and also to compare the predation of Grapsid crab Goniopsis cruentata and the Ocypodid Ucides cordatus over the propagules of three mangrove trees: Rhizophora mangle, Avicennia schaueriana e Laguncularia racemosa. Specifically, we tested the hypothesis that Goniopsis predation is more important that Ucides predation, and that these consumers have antagonist effects over propagule consumption. In each area, 10 quadrates were selected at random to analyze tree richness, diameter, height, tree biomass and crab richness and density five years after restoration experiment start. Results show that tree height, biomass and crab density were significantly higher in artificially restored area. No significant differences were observed in crab species richness between areas, but higher tree richness was observed in self-recovered area. Results suggest that planting propagules of Rhizophora can significantly increase tree recovering if the aim was increase tree biomass and crab density, which can accelerate return of ecological functionality. Goniopsis is a more important propagule predator than Ucides both in natural and restored areas. The effects of Goniopis were higher in absence of Ucides, due to negative interactions among these two predator species. The preference of Goniopsis by Avicennia and Laguncularia can favor the dominance of Rhizophora observed in Neotropical mangroves. This study suggests that propagule predation by Goniopsis should be controlled in restoration programs, if dominance of Rhizophora is undesirable respect to more rich tree communities

Em cada ?rea, 10 quadrantes foram aleatoriamente selecionados para analisar a riqueza arb?rea, di?metro, altura, biomassa arb?rea e riqueza e densidade de caranguejos cinco anos ap?s o in?cio do experimento de restaura??o. Os resultados mostraram que tanto a altura e biomassa arb?reas quanto a densidade de caranguejos foram significativamente maiores na ?rea artificialmente restaurada. N?o foram observadas diferen?as significativas na riqueza de esp?cies de caranguejos entre as ?reas, mas houve uma maior riqueza de esp?cies de ?rvores na ?rea auto-recuperada. Estes resultados sugerem que o plantio de prop?gulos de Rhizophora pode aumentar significativamente a recupera??o da cobertura vegetal, se o objetivo for elevar a biomassa arb?rea e a densidade de caranguejos, o qual pode acelerar o retorno da funcionalidade ecossist?mica. Goniopsis foi um predador de prop?gulos mais importante que Ucides tanto em ?reas naturais quanto restauradas. Os efeitos de Goniopsis foram maiores na aus?ncia de Ucides devido a intera??es negativas entre estas esp?cies de predador. A prefer?ncia de Goniopsis por Avicennia e Laguncularia pode favorecer a domin?ncia de Rhizophora observada nos mangues Neotropicais. Este estudo sugere que a preda??o de prop?gulos por Goniopsis em programas de restaura??o de mangue deveria ser controlada se a domin?ncia de Rhizophora ? indesej?vel em rela??o a comunidades com mais esp?cies de ?rvore

Full textAbstract:
The Florida Everglades ecosystem is threatened by human development, increased pollution, freshwater scarcity, and invasive species; factors that have negatively impacted the Everglades and native species health and populations. Man-made canals and levies have redirected the natural flow of fresh water from Lake Okeechobee into the Florida Everglades, starving central and south Florida ecosystems of necessary fresh water and nutrients. Through the efforts of the Comprehensive Everglades Restoration Project (CERP), freshwater is being redirected back into central and south Florida, returning the sheet flow of water back into the Everglades. Monitoring species abundance in the Everglades is a beneficial conservational tool for assessing restoration efforts from CERP. As a semi-aquatic apex predator, river otters (Lontra canadensis) are a useful health bio-indicator for the Florida Everglades. In order to conduct future population studies of river otters in the Florida Everglades, it must first be ascertained where they can be found and what time of year they are most likely to be sighted. For this study, Moultrie infrared game cameras were used to photograph the presence or absence of river otters within the five main habitats in the Everglades; the pinelands, hardwood hammock, cypress swamp, marsh prairie, and mangrove estuary at two protected areas in the Florida Everglades (Big Cypress National Preserve and Fakahatchee Strand State Park). River otters were most frequently sighted in the hardwood hammock habitat, but were also found in the cypress swamp. The large majority of river otter sightings occurred during dry season, which is thought to be a function of restricted water availability and aquatic mobility. Future population studies of river otters would be most productive in the hardwood hammock and cypress swamp habitats during dry season. Game camera images along with field opportunistic sightings, resulted in a variety of species documented. This provided valuable information of species richness and distribution within and amongst the habitats. The hardwood hammock was found to be the most species rich habitat, having over half the species observed in the study in this habitat. The Aves class was the most abundantly observed in the Everglades, and was most frequently sighted during the dry season. As a refuge for migratory birds, the Everglades house the majority of bird species during the winter months, which occur during dry season. The Aves class was most frequently sighted in the pinelands habitat during dry season. This habitat, being the highest in elevation and therefore the driest, shows a stronger resemblance to most northern bird habitats then does the water-saturated wetlands found throughout the Everglades. The mangrove estuary was the most commonly occurring outlier, having the least species overlap when compared to the other habitats. All other habitats in the Everglades are freshwater wetlands, while the mangrove estuary is a brackish environment, which limits the species that are unable to tolerate saline conditions. Further studies of species abundance throughout the Everglades will aid in monitoring CERP restoration efforts over time.

Full textAbstract:
An assessment was made of American Samoa mangroves' vulnerability and
predicted changes in position from sea-level rise. The study also evaluated
capacity in the Pacific Islands region to assess mangrove vulnerability to
climate change and institute adaptation measures. Of the outcomes from
climate change, relative sea-level rise may be the greatest threat to
mangroves. By 2100, mangrove losses from relative sea-level rise could be
as high as 47 percent in American Samoa and 22 percent when extrapolating
regionally, causing about a quarter of total predicted annual regional losses.
American Samoa mangrove vulnerability to sea-level rise was
determined and future position was predicted through analyses of sea-level
trends and projections, mangrove spatial change analysis, reconstruction and
monitoring of sedimentation rates, and determination of potential migration
areas. These analyses provided three categories of requisite information: (i)
Observed and projected rate of change in sea-level relative to the mangrove
sediment surface, determined from trends in relative sea-level through
analysis of sea-level data from a local tide gauge and observations of trends
in the elevation of mangrove sediment surfaces; (ii) observed and projected
trends in mangrove seaward margin positions; and (iii) physiographic settings
(slope of land upslope and location of obstacles along the landward margin).
Results indicate that American Samoa mangroves are not likely
keeping pace with rising sea-level, both surface and subsurface process
controls on sediment elevation are important factors, and a large proportion
(16, 23 and 68 percent) of the landward margins of the three mangrove study
sites are obstructed from natural landward migration with sea-level rise.
Based on observed trends in sediment surface elevations and movement of
two mangroves' seaward margins, these sites have likely not been keeping
pace with relative sea-level rise, with an elevation deficit of about 2 mm eat
both sites. An embayment mangrove experienced sea-level rise relative to
the mangrove sediment surface of 2.22 (± 2.22 95% Cl) mm a-1 and a basin
mangrove experienced 1.97 (± 0.32 95% Cl) mm a -1 . At these sites, a highly
significant positive correlation between the change in position of the seaward
margins and change in relative sea-level suggests that rising sea-level
relative to the mangrove surface caused the observed landward migration.
Shoreline movement was not significantly correlated with changing sea-level
at a third site, where development activities have likely been dominant factors
determining changes in mangrove position; vulnerability, based on
observations of trends in sediment surface elevation, was not determined for
this third site.
This study was the first to employ broad spatial coverage and a large
number of sampling locations (330 sampling locations) to observe trends in
the elevation of two mangroves' sediment surfaces, a necessary sampling
design to adequately characterize mangrove sites, based upon previously
documented high spatial variability in trends in mangroves' surface elevation.
Both surface and subsurface processes exhibited large controls on sediment
elevation, highlighting the need to monitor the full soil profile to accurately
measure trends in mangrove surface elevation. Highly significant different
mean changes in sediment surface elevation occurred for mangroves in
different geomorphic settings (a difference of 3.4 [± 1.3 SE] mm a -1 , N =
1412, P<0.007), supporting the hypothesis that mangroves in an
estuarine/drowned river valley composite geomorphic setting are more
resistant to relative sea-level rise than embayment mangroves. Mean
landward migration of the mangroves' seaward margins was 12 to 37 times
the relative sea-level rise rate. This is the first documentation of significantly
different mean sediment surface elevation change for mangroves in different
geomorphic settings, and the first documentation of the relationship between
the rate of seaward mangrove margin erosion and relative sea-level rise rate,
information needed to develop reliable predictive elevation models for
mangrove ecosystems. Changes in extreme high water levels and frequency
were found to not pose an increasing threat to American Samoa mangroves
beyond the effects from rising mean sea-level. This site-specific assessment
supports the hypothesis that, in this region, which experiences large El Nino
Southern Oscillation-related steric changes lasting several months to years,
extreme high waters are likely to be related to mean sea-levels.
This was the first comprehensive assessment to determine both (i)
whether the mangrove site's threshold for resistance to sea-level rise has
been exceeded, and (ii) the site's capacity to naturally migrate landward in
response to rising sea-level. This was the first study to select research
methods suitable for employment in Pacific Small Island Developing States,
considering both cost and staff abilities.
Results support instituting adaptation measures in American Samoa to
reduce obstacles to landward mangrove migration with sea-level rise and to
manage activities within catchments that affect mangrove elevation.
Regionally, there is extremely low capacity to assess mangrove vulnerability
to climate change and to institute adaptation measures. Regional adaptation
priorities include coastal planning that facilitates mangrove migration with
sea-level rise, better management of non-climate stressors, and identification
of climate change impacts on mangroves through regional standardized
monitoring.

Full textAbstract:
Tidal wetlands such as mangroves and salt marshes possess many valuable attributes, ranging from forest and fishery products to ecosystem services such as shoreline protection and water filtration. In many parts of the world, past impacts and current pressures threaten the viability of these areas. There is wide interest in mangrove restoration, with increasing focus on the functional aspects of rehabilitated systems. Achieving these goals requires attention to restoring linkages, such as those between mangroves and adjacent salt -tolerant vegetation types, including salt marshes.

Full textAbstract:
Mangrove forest restoration projects undertaken globally to date have had significant issues and limitations and "most attempts to restore mangroves often fail completely or fail to achieve the stated goals" (Lewis, 2005). The root cause of many of the issues associated with mangrove restoration is that knowledge of the underlying factors controlling spatial patterns in mangroves is often lacking or not integrated into design of restoration projects, impeding the successful restoration of these critical ecosystems.
To improve the success of restoration and address many of the issues associated with the current paradigm for mangrove restoration, there is a need to develop an evidence based approach to the planning and implementation of mangrove restoration projects. The current thesis demonstrates the need for an evidence based approach to mangrove restoration through implementation of case studies in lower intertidal mangrove communities of the Ngao river, located in the Kraburi river estuary, Ranong province, southern Thailand and development of a series of recommendations on how to incorporate this improved evidence base into different phases of mangrove restoration projects.
The case studies target identified gaps in knowledge of the different stages of the mangrove tree life cycle through: observational studies on mature tree forest composition and spatial patterns in two forest types; observational studies and experiments examining the dispersal and development of mangrove propagules and seeds and establishment of released propagules in experimental enclosures; and experiments examining the survival and growth of transplanted seedlings in the two lower intertidal forest communities, with distance from the Ngao river and inside and outside canopy gaps.
Chapter 2 of the thesis documents the findings of the first case study and showed that the two lower intertidal forest communities included in the study, the "Aegiceras forest" and the "Sonneratia-Avicennia forest", were low in mangrove tree species diversity and differed based on species similarity in assemblages of mature trees and differences in forest structure parameters of dominant species. Within each of the two forest types, assemblages of mature trees also differed with distance from the Ngao river with the study confirming the presence of distinct spatial patterns or zones within each of the two forest types. Duration of tidal inundation was found to be an important determinant of forest structure in the two forest types, significantly correlated with assemblages of mature trees as well as key forest structure parameters.
These correlations and the differences in natural assemblages of mature mangrove trees between the two forest types and further significant differences with distance from the Ngao river in the "Aegiceras forest", suggest that assemblages of mature trees are related to hydroperiod and duration of inundation but that forest communities in both the "Aegiceras forest" and "Sonneratia-Avicennia forest" could have a broad tolerance to hydroperiod characteristics of the two forest types. Within the two forest types, the physical effects associated with more exposed locations close to the Ngao river appear to determine within forest spatial patterns, with A.corniculatum seemingly less tolerant of these more exposed locations than A.alba and S.alba but a better competitor than A.alba and S.alba at more sheltered sites inland.
Chapter 2 also provided information on the demographics of mature trees in the two forest types, which suggest that secondary succession has possibly taken place within the "Aegiceras forest" in the past with A.corniculatum trees taking over from S.alba and A.alba trees, a pattern which is possibly currently being repeated in the "Sonneratia-Avicennia forest". These patterns of secondary succession have not previously been documented before in these lower intertidal communities.
The second case study, described in Chapter 3 focused on propagules and developing seedlings and had two components. The first component was a propagule dispersal study which showed that assemblages of propagules and developing seedlings differed between the two lower intertidal forest types, as did the propagule and immature seedling forest structure parameters of the three dominant species A.corniculatum, A. alba and S.alba. Assemblages of propagules and developing seedlings also differed with distance from the Ngao river with the greatest density of A.corniculatum propagules and seedlings in the "Aegiceras forest" found in the middle zone of the forest and the lowest density found in the zone immediately adjacent to the Ngao river and inland. A.alba propagules and seedlings had contrasting spatial patterns and were confined to quadrats closest to the Ngao river. In the "Sonneratia-Avicennia forest", A.corniculatum seedling density was also related to the distance from the Ngao river, highest in the zone adjacent to the river and lowest inland. The propagule dispersal study also found clear seasonal variation in propagule and seedling abundance of the dominant species and seasonal differences between forest types, with seedlings of the dominant species tending to persist across the year in the "Sonneratia-Avicennia forest" but not in the "Aegiceras forest".
The second component of Chapter 3 was a propagule release experiment which showed that a greater proportion of A. corniculatum propagules released into enclosures developed into mature seedlings in the "Aegiceras forest" than the "Sonneratia-Avicennia forest". In contrast, a greater proportion of A.alba propagules developed into mature seedlings in the "Sonneratia-Avicennia forest". The rate of propagule development was also related to distance from the Ngao river. For A. corniculatum the highest proportion was found in the middle of the forest dominated by A.corniculatum trees, while in contrast, a greater proportion of A.alba propagules developed into mature seedlings in plots further away from the Ngao river outside the area dominated by mature A.alba trees.
The results suggest that differences in assemblages of propagules and seedlings between the two forest types are closely related to the mature forest composition and the Importance value of conspecific trees in the canopy. Within the two forest types, the results also support the secondary role of duration of inundation, with physical effects associated with more exposed locations close to the Ngao river appearing to determine within forest distribution patterns of A.corniculatum propagules and seedlings which were seemingly less tolerant to exposed locations than propagules and seedlings of A.alba and S.alba.
The results described in Chapter 3 also suggest differences in reproductive strategy amongst species and provides additional evidence of secondary succession through observations of: (1). A wide distribution of A.corniculatum propagules and seedlings across the study area; and (2). persistence of A.corniculatum propagules and seedlings over an annual period in the "Sonneratia- Avicennia forest". These results add weight to the theory espoused in Chapter 2 of the thesis that A.corniculatum is expanding its range in the "Sonneratia-Avicennia" forest, replacing the dominant S.alba and A.alba, perhaps in the same manner as this species has done in past in the "Aegiceras forest".
The third case study documented in Chapter 4, was a transplant study focusing on A. corniculatum and S.alba seedlings. Results showed that survival and growth of transplanted seedlings of both species was greater in the "Sonneratia-Avicennia forest" than the "Aegiceras forest". S.alba seedlings showed a particularly strong preference for environmental conditions in the "Sonneratia-Avicennia forest" type. Survival and growth of seedlings of both species also increased with distance from the Ngao river in both forest types. This trend was especially pronounced for f A.corniculatum seedlings. The proportion of transplanted seedlings of both species surviving also differed with canopy type, with a greater proportion of seedlings surviving in light gaps than under the forest canopy. Canopy type had less of an effect on survival of A.corniculatum seedlings than on S.alba seedlings, which showed a strong preference for light gaps as opposed to locations under the forest canopy. Canopy type had less of an effect on survival of transplanted seedlings in the "Sonneratia-Avicennia forest" than it did in the "Aegiceras forest" and also had less of an effect on survival of transplanted seedlings in the quadrats closest to the Ngao river than it did further inland.
In both forest types the survival and growth of transplanted seedlings of both species was correlated with the percentage of time that they were inundated by tides, and the survival and growth of both species increased as the proportion of the day in which the site was inundated decreased.
Clear differences in survival and growth of transplanted seedlings of the two species appears to be related to significantly different levels of light availability in the two forest types resulting from the differing forest structure of these two lower intertidal communities, the denser, more closed canopy of the "Aegiceras forest" and the more open canopy "Sonneratia-Avicennia forest" as reported in Chapter 2 of this thesis. Within the two forest types, a secondary role of duration of tidal inundation appears to exist, with physical effects associated with more exposed locations close to the Ngao river appearing to influence seedling survival and growth patterns, both of which were significantly greater in plots away from the Ngao river than plots close to it. A.corniculatum seedlings were seemingly less tolerant to these more exposed locations than those of S.alba. The effects of light level and physical disturbance on seedling establishment, although not unequivocal, are consistent with results from the literature and also provide further insights into tolerances of the two lower intertidal species to environmental conditions typically observed at restoration sites.
Chapter 5 of the thesis summarises the results of the case studies and makes recommendations for how to incorporate each aspect of the improved evidence base arising from the case studies, into different phases of mangrove restoration projects. A table making explicit links between the case studies and restoration is included as was a concept for a decision support system for restoration of lower intertidal forests in the form of a flow chart based on results of studies of mature forest, propagules and seeds and mature seedlings. The flow chart demonstrates how each piece of evidence could potentially be applied in practice to enable the best decisions on which mangrove restoration approach to adopt to be made in an objective manner. For example information on hydroperiod, combined with information on site exposure and level of natural recruitment at the site would result in a specific recommendation for restoration of a site with either A.corniculatum, S.alba or A.alba seedlings where natural recruitment at the selected site was insufficient. Incorporated together with the improved evidence base on lower intertidal forests developed through the three case studies, the decision support system can potentially serve as a practical tool for the integration of scientific knowledge about mangrove ecosystems into restoration planning and ultimately improve the results of restoration and assist in the recovery of these essential ecosystems.

Full textAbstract:
Abstract Despite their limited global distribution, mangroves have gained attention as a potential carbon offset option due to their high carbon storage capacity and diverse social and environmental co-benefits. Carbon stock in mangroves (global average=2,790tCO2eq/ha) is about four times higher than in terrestrial forests and contributes to almost 10% (37GtCO2eq) of global terrestrial carbon pool. Mangrove carbon sequestration averages 6.9tCO2eq/ha/yr but may reach more than 20tCO2eq/ha/yr. Literature suggests that over 812,000ha of mangrove areas, spread over 106 countries/territories, show potential for restoration. Furthermore, globally, mangroves have been lost at a rate of 1-2%/yr, which may account for an annual emission of about 0.09-0.45 GtCO2eq/yr that can be potentially avoided through conservation actions. Mangroves within the Niger Delta Region (NDR) cover 800,000ha (6% of world extent), and contain an estimated carbon stock of 2.2GtCO2eq. In 2017, Eni's subsidiary Nigerian Agip Oil Company (NAOC) launched a voluntary initiative to restore mangroves to promote social and biodiversity benefits while also contributing to offsetting its GHG emissions. A 30-ha pilot restoration area was identified in Okoroma, Bayelsa, where mangroves had failed to naturally recover from oil spills caused by third party interference in 2014. Site assessments were carried out in 2018 and indicated residual soil contamination (hydrocarbons/metals) and low fertility, a typical characteristic of soils in the NDR. A restoration trial (n=90 seedlings) using nursery-reared seedlings resulted in 100% survivorship and high growth rates, confirming the feasibility of active restoration across the entire site. Although soil contamination was lower than when the spills occurred, we concluded that the combination of residual contamination, low soil fertility and site topography had restricted the natural regeneration process. This in turn risked further soil degradation and ultimately erosion and permanent habitat loss. To prevent this from happening, a long-term restoration program based on the transplantation of fertilized seedlings in partnership with local communities is proposed. In addition to the benefits to the local communities and the environmental restoration, this project is expected to allow for the sequestration of 2,970tCO2eq in 20 years and avoid the emission of an estimated 60,000tCO2eq from soil carbon, numbers that could be scaled up in the future to a much larger area. The results of this case study further confirm the possibility of using mangroves as a Natural Climate Solution to offset GHG emissions from O&G operations.

At the cutting edge of the 4th Industrial Revolution (4IR) movement across the world, the utilization of drones for reforestation at a large scale puts the United Arab Emirates (UAE) as a pioneer not only in the Arabian Peninsula, but across the world. With only a handful of countries trying new mechanisms for aerial planting, and none at a large scale in the arid conditions of the Arabian Peninsula, Abu Dhabi National Oil Company (ADNOC) has therefore been advancing science and this methodology. The objective of our project is to present the role of innovative technologies in supporting nature-based solutions through ADNOC's pilot project in utilizing drones for mangrove restoration along Abu Dhabi coast. ADNOC targets the plantation of 10 million mangroves by 2030. Those efforts support UAE's commitment of planting 100 million mangroves by 2030. Drone habitat restoration projects support countries to meet the challenge of the United Nations (UN) Sustainable Development Goals (SDGs), United Nations Framework Convention on Climate Change (UNFCCC) commitments, and UN Convention on Biological Diversity (CBD) related targets amongst other ecological related commitments. This project is aligned align with and advance the below SDGs:

Abstract Over the last decades, anticipating on the global increase in energy demand, necessary developments on the seabed have taken place that interfered with ocean ecosystems and related biodiversity enhancement capacities. As the awareness of this problem nowadays grows - as well as the efforts of large scale ecosystem restoration - the need for a reliable solution targeting the core of the problem does so as well: insufficient availability of environmental information to support decision making systems. By introducing AI-driven ecosystem insights, the nature inclusive scope on projects can be broadened and decision making as well as environmental requirements within the marine industry can be brought to a higher level. In working towards biodiversity enhancement at scale, creating a Digital Twin of the project site can give direction for decision making. This interactive digital blueprint offers valuable insights into the physical assets and the potential of integrating state-of-the-art biodiversity solutions. Following from our experience, we know that the protection and restoration of seaweed, oyster and mussel reefs, seagrass, coral and mangroves can significantly increase the ecosystem services they deliver. The Digital Twin will relate ecosystem services with economic indicators and show amongst others; the potential biodiversity increase, CO2 sequestration, oxygen level increase and corresponding revenues. It can track the impact and continuously demonstrate progress and status by integrating 3rd party monitoring and data collection methods.Worldwide offshore energy systems develop more and more towards multi-use, which is key to enhancing seabed biodiversity. The opportunities for multi-use are endless, but the inclusion of ecosystem restoration can only be successful if the right data is collected and insights can be shown. If we can better understand the system in which the intervention is taking place, we can better make the right decisions.An intelligent tool to create high traction and impact on marine ecosystems at scale, as it facilitates energy companies and operators to evaluate targeted and high-value environmental solutions. It will break down the complex challenge of biodiversity, and allows for easy and impactful decision-making on this topic. This will release pressure on specific species, and nature in general, and will allow them to thrive again.Efforts to enhance ecosystem services, combined with AI-driven insights, unleash a new sea of opportunities for nature inclusive works. Currently under development in collaboration with universities and research institutes, our aim with this paper is to inspire and invite marine industry partners to join our upscaling efforts.

Full textAbstract:
This chapter describes tools and a methodology to model wind and flood risks from tropical storms under present and future climate accounting for natural infrastructure. Wind forcing provide a crucial link to hydrodynamic models that can be used in risk assessments to estimate extent of and damages from flooding and erosion. Further, such flood risk models can then include the effects of ecosystems, such as mangroves, to model the effects on risk of conservation and restoration outcomes but also individual nature-based projects to reduce risks. The chapter describes hazard modeling techniques and presents simple applications to (1) assess the effect of climate change in the Caribbean, by estimating wind fields for tropical cyclones for present and future climate scenarios, (2) address the limited observations in hurricane data by using existing tools to derive synthetic storms and readily use them in coastal models, and (3) compare modeling approaches and datasets to provide recommendations for assessing flood attenuation of mangroves. The results and data developed in these applications is available with this chapter to be used in other local applications, or to infer damages from wind or in flood hazard models.

Full textAbstract:
This Regional Sediment Management technical report outlines initial steps to implement a proof-of-concept physical model to develop demonstration-scale evidence that supports managed wetland transgression through sediment augmentation via a thin-layer placement strategy. The proof-of-concept physical model will evaluate the ability of thin-layer placement to increase elevation and enhance recruitment within coastal scrub mangrove wetlands most vulnerable to sea-level rise. The investigation sought to identify feasible project locations, sediment sources that included beneficial use of dredged material opportunities, and environmentally acceptable construction techniques. Results of this initial step will be used to secure funding to permit, construct, implement, and monitor the proof-of-concept physical model. The results of this initiative will inform and direct management measure development for the ongoing Biscayne Bay Southeastern Everglades Restoration Project, the only coastal component of the Comprehensive Everglades Restoration Plan and the only component with an obligation to increase habitat resilience. Results are applicable to areas throughout the Gulf, Atlantic, and Pacific Coasts of the United States where direct preservation, enhancement, and restoration of mangrove and other coastal wetland communities will build coastal resiliency, reduce storm hazards damage, and create habitat for a variety of fish and wildlife species, particularly as sea levels rise.

The Everglades National Park and Big Cypress National Preserve vegetation mapping project: Interim report—Northwest Coastal Everglades (Region 4), Everglades National Park (revised with costs). National Park Service, November 2020. http://dx.doi.org/10.36967/nrr-2279586.
Full textAbstract:
The Everglades National Park and Big Cypress National Preserve vegetation mapping project is part of the Comprehensive Everglades Restoration Plan (CERP). It is a cooperative effort between the South Florida Water Management District (SFWMD), the United States Army Corps of Engineers (USACE), and the National Park Service’s (NPS) Vegetation Mapping Inventory Program (VMI). The goal of this project is to produce a spatially and thematically accurate vegetation map of Everglades National Park and Big Cypress National Preserve prior to the completion of restoration efforts associated with CERP. This spatial product will serve as a record of baseline vegetation conditions for the purpose of: (1) documenting changes to the spatial extent, pattern, and proportion of plant communities within these two federally-managed units as they respond to hydrologic modifications resulting from the implementation of the CERP; and (2) providing vegetation and land-cover information to NPS park managers and scientists for use in park management, resource management, research, and monitoring. This mapping project covers an area of approximately 7,400 square kilometers (1.84 million acres [ac]) and consists of seven mapping regions: four regions in Everglades National Park, Regions 1–4, and three in Big Cypress National Preserve, Regions 5–7. The report focuses on the mapping effort associated with the Northwest Coastal Everglades (NWCE), Region 4 , in Everglades National Park. The NWCE encompasses a total area of 1,278 square kilometers (493.7 square miles [sq mi], or 315,955 ac) and is geographically located to the south of Big Cypress National Preserve, west of Shark River Slough (Region 1), and north of the Southwest Coastal Everglades (Region 3). Photo-interpretation was performed by superimposing a 50 × 50-meter (164 × 164-feet [ft] or 0.25 hectare [0.61 ac]) grid cell vector matrix over stereoscopic, 30 centimeters (11.8 inches) spatial resolution, color-infrared aerial imagery on a digital photogrammetric workstation. Photo-interpreters identified the dominant community in each cell by applying majority-rule algorithms, recognizing community-specific spectral signatures, and referencing an extensive ground-truth database. The dominant vegetation community within each grid cell was classified using a hierarchical classification system developed specifically for this project. Additionally, photo-interpreters categorized the absolute cover of cattail (Typha sp.) and any invasive species detected as either: Sparse (10–49%), Dominant (50–89%), or Monotypic (90–100%). A total of 178 thematic classes were used to map the NWCE. The most common vegetation classes are Mixed Mangrove Forest-Mixed and Transitional Bayhead Shrubland. These two communities accounted for about 10%, each, of the mapping area. Other notable classes include Short Sawgrass Marsh-Dense (8.1% of the map area), Mixed Graminoid Freshwater Marsh (4.7% of the map area), and Black Mangrove Forest (4.5% of the map area). The NWCE vegetation map has a thematic class accuracy of 88.4% with a lower 90th Percentile Confidence Interval of 84.5%.

Full textAbstract:
This deliverable synthesizes the results on public perceptions of marine CDR methods from the first two years of OceanNETs. The purpose is to inform the other work packages in OceanNETs and stakeholders about our results in a timely and brief manner about the ways members of the public view marine CDR specifically but also in the broader context of net-zero targets and climate policy. The deliverable summarises results of two studies: (1) focus groups held in Germany and Norway that covered ocean fertilization, ocean alkalinity enhancement, artificial upwelling and blue carbon management and (2) a deliberative survey in Norway that covered ocean alkalinity enhancement, macroalgae farming with BECCS or biomass sinking and land-based BECCS and enhanced weathering as terrestrial approaches for comparison. Participants in both studies emphasise the importance of reducing emissions and changing consumptions patterns. They hardly discuss the need to remove CO2 from the atmosphere to reach the Paris climate goal and the concept of negative emissions seems difficult for them to engage with. Among the methods, participants prefer ecosystem-based approaches like mangrove or seagrass restoration over other methods like alkalinity enhancement or ocean fertilization. Participants are concerned about the actual feasibility of deployment at a relevant removal scale and for a longer period. Connected to this are concerns about the controllability of the deployment and the methods’ impact, like difficulties to control negative environmental effects from biomass sinking at the seafloor. They also question the buildup of additional infrastructure or additional interventions into nature on top of already existing human interference. The opportunity to deliberate the methods increases participants’ certainty about their assessment but only slightly changes the direction of the assessment.

Full textAbstract:
The Carbon Dioxide Removal (CDR) market is experiencing rapid development, with different regions adopting distinct approaches. In Europe, the progress is primarily driven top-down through the implementation of regulations aimed at integrating CDR into various climate instrument pillars within the EU. In contrast, the United States is witnessing a bottom-up growth trajectory, characterized by the emergence of start-ups, carbon registries, marketplaces, and insurance companies, all playing a role in the expansion of the CDR sector. This surge in CDR-related businesses has been further catalyzed by substantial subsidies, particularly through the recent adjustments made to the 45Q tax credit system. The amendments were introduced as part of the "Inflation Reduction Act" (IRA) and the "Bipartisan Infrastructure Law" (BIL). Under these modifications, significant tax credits are offered for carbon capture and utilization at point sources, with subsequent storage (CCS). Notably, the tax credits have increased to 60 USD/tCO2 for carbon capture and utilization and storage at point sources, and to 85 USD/tCO2 for direct air capture and storage. The tax credits go even higher, amounting to 130 and 180 USD/tCO2, respectively, for utilization and storage if the carbon is directly removed from the air. In addition to these measures, the IRA and BIL also allocate substantial funding for forestry and sequestration projects, carbon transport infrastructure, and carbon removal hubs to test and develop technologies. Simultaneously, some top-down initiatives have been set in motion in the US, exemplified by the introduction of the Carbon Dioxide Removal Market Development Act as part of California's Cap-and-Trade Program. This act mandates emitting entities to offset a certain percentage of their emissions through CDR in subsequent years, culminating in full compensation of emissions with CDR by 2045. Moreover, the act emphasizes the promotion of domestic development by requiring that at least 50% of the negative emissions credits used by an emitting entity originate from CDR processes that directly mitigate climate impacts within the state. Against this backdrop, it comes as no surprise that the CDR start-up scene is predominantly dominated by US companies, with ocean-based removal companies accounting for approximately 10 percent of the market. However, despite their presence, ocean-based CDR projects are currently limited, with the majority focused on blue carbon projects, particularly mangrove restoration, and only a few exploring other ocean-based CDR methods. The land-based portion of the CDR market appears to be effectively addressing accounting, verification, and registry aspects, primarily due to market demand or existing regulations. Nevertheless, the development of such bottom-up approaches remains less likely for open access schemes like ocean-based CDR initiatives.

Full textAbstract:
St. Croix is home to a variety of threatened and endangered (T&E) species that are at risk for predation by the invasive red-tailed boa (Boa constrictor), such as the St. Croix ground lizard (Amevia polyps), the ground-nesting least tern (Sterna antillarum), and the hawksbill sea turtle (Eretmochelys imbricata). Genetic analysis determined the original red-tailed boa population on St. Croix sourced from a single female released by a pet owner and its range expands every year. Presently, the main population of red-tailed boa is established on the west end of St. Croix and extends as far east as Salt River. One individual was found in Salt River Marina and additional sightings have occurred in Salt River Bay National Historical Park and Ecological Preserve (SARI) more recently. This inventory aims to search for red-tailed boas in two focal areas that park staff are actively restoring. The park will use information from this inventory to develop a boa removal program and protect sensitive native species like the ground-nesting least tern, the St. Croix ground lizard and the hawksbill sea turtle nests and increase the success of restoration. Snakes are cryptic species, often occurring in low density, and utilize complex habitat patterns. To increase the likelihood of detecting red-tailed boa, the Maryland/Delaware/D.C. Wildlife Services detector dog handling team partnered with the USDA-APHIS National Detector Dog Training Center to train and develop detector dogs to assist in determining the presence/absence of red-tailed boa for this project. Canines were trained to locate red-tailed boa and indicate its presence to the handler via barking three times near the identified target. Two dog detector teams traveled to Salt River Bay National Park (SARI) in St. Croix to conduct surveys for red-tailed boa in habitats likely to contain red-tailed boa in June 2023. Habitat varied throughout the surveys. Close to the bay, mangrove forests dominated and, as elevation increased, transects took place in almost exclusively dry tropical shrub forest. Each transect was surveyed by one dog team. The canine teams had no red-tailed boa detections within SARI. Canines showed proficiency at surveying for red-tailed boa populations in SARI. Given the proximity of confirmed detections to SARI, it is likely red-tailed boa will be in the park in the future, if they are not already. Additional surveys, whether by humans, canines, or both, are recommended in areas of the park that have not been previously surveyed.
