This paper presents an approach for incorporating species-conditional co-occurrence into models used for the selection of marine indicator species. Mangrove invasion within the Siangshan Wetland in Hsinchu, Taiwan, has changed the original structures and functions of habitats for benthic organisms. The Hsinchu City Government ran a large-scale mangrove removal project from October 2015 to March 2016 to restore the wetland. From October 2015 to September 2016, we investigated the biological effects of mangrove removal on benthic crabs and their adjacent habitats. Density, number of species, Shannon–Weaver index (H′) and Palou’s evenness index (J′) were calculated and compared between mangrove and non-mangrove regions. The results showed that values for these attributes in the non-mangrove regions were higher than those of the mangrove regions. After mangrove removal, species returned to their original habitats and the related density increased significantly. Using conditional co-occurrence algorithms, we identified five indicator species (Mictyris brevidactylus, Macrophthalmus banzai, Uca arcuata, Uca lacteal and Uca borealis) with high co-occurrence probabilities, whose population responses provided direct evidence of the benefits of mangrove removal for wetland restoration. The results indicate that mangrove removal is an appropriate habitat rehabilitation strategy for benthic organisms, and that the chosen indicator species may provide valuable ecological information for coastal managers seeking to control the spread of mangroves.

Mangrove degradation is a well-documented trend, but the spread of mangroves within the Siangshan Wetland in Hsinchu, Taiwan, runs contrary to that trend. The spread of mangroves changes the structure and functions of habitats for benthic organisms, causes infilling of estuaries and flooding and creates breeding grounds for small black mosquitoes. A large-scale mangrove-removal project was undertaken by the Hsinchu City Government from October 2015 to March 2016. They also investigated the consequences of mangrove removal on benthic organisms and adjacent habitats from October 2015 to September 2016, and the density, species count, Shannon–Wiener index (H′), and Pielou’s evenness index (J′) of the mangrove and non-mangrove regions were compared. In this study, we used satellite telemetry images to monitor fluctuations in mangrove density from 2006 to 2016. The non-mangrove region exhibited more variations than the mangrove region. After mangrove removal, species returned to their original habitats and noteworthy biological values significantly increased in the mangrove regions. This study presents evidence to argue that mangrove removal benefits benthic organisms. The results indicate that mangrove removal can be an appropriate habitat rehabilitation strategy for benthic organisms. The ecological findings of this study can inform coastal managers or other officials who seek to steward mangrove biomass.

This study presents a new global baseline of mangrove extent for 2010 and has been released as the first output of the Global Mangrove Watch (GMW) initiative. This is the first study to apply a globally consistent and automated method for mapping mangroves, identifying a global extent of 137,600 km 2 . The overall accuracy for mangrove extent was 94.0% with a 99% likelihood that the true value is between 93.6–94.5%, using 53,878 accuracy points across 20 sites distributed globally. Using the geographic regions of the Ramsar Convention on Wetlands, Asia has the highest proportion of mangroves with 38.7% of the global total, while Latin America and the Caribbean have 20.3%, Africa has 20.0%, Oceania has 11.9%, North America has 8.4% and the European Overseas Territories have 0.7%. The methodology developed is primarily based on the classification of ALOS PALSAR and Landsat sensor data, where a habitat mask was first generated, within which the classification of mangrove was undertaken using the Extremely Randomized Trees classifier. This new globally consistent baseline will also form the basis of a mangrove monitoring system using JAXA JERS-1 SAR, ALOS PALSAR and ALOS-2 PALSAR-2 radar data to assess mangrove change from 1996 to the present. However, when using the product, users should note that a minimum mapping unit of 1 ha is recommended and that the error increases in regions of disturbance and where narrow strips or smaller fragmented areas of mangroves are present. Artefacts due to cloud cover and the Landsat-7 SLC-off error are also present in some areas, particularly regions of West Africa due to the lack of Landsat-5 data and persistence cloud cover. In the future, consideration will be given to the production of a new global baseline based on 10 m Sentinel-2 composites.

Mangrove is located in the tropical and subtropical regions and brings good services for native people. Mangrove in the world has been lost with a rapid rate. Therefore, monitoring a spatiotemporal distribution of mangrove is thus critical for natural resource management. This research objectives were: (i) to map the current extent of mangrove in the West and Central Africa and in the Sundarbans delta, and (ii) to identify change of mangrove using Landsat data. The data were processed through four main steps: (1) data pre-processing including atmospheric correction and image normalization, (2) image classification using supervised classification approach, (3) accuracy assessment for the classification results, and (4) change detection analysis. Validation was made by comparing the classification results with the ground reference data, which yielded satisfactory agreement with overall accuracy 84.1% and Kappa coefficient of 0.74 in the West and Central Africa and 83.0% and 0.73 in the Sundarbans, respectively. The result shows that mangrove areas have changed significantly. In the West and Central Africa, mangrove loss from 1988 to 2014 was approximately 16.9%, and only 2.5% was recovered or newly planted at the same time, while the overall change of mangrove in the Sundarbans increased approximately by 900 km<sup>2</sup> of total mangrove area. Mangrove declined due to deforestation, natural catastrophes deforestation and mangrove rehabilitation programs. The overall efforts in this study demonstrated the effectiveness of the proposed method used for investigating spatiotemporal changes of mangrove and the results could provide planners with invaluable quantitative information for sustainable management of mangrove ecosystems in these regions.

Abstract Rapid developments on the coastal regions have become a major thread to mangrove ecosystems. The conversion of mangrove forest into fish ponds, housing and industrial sites make the area of this unique tropical ecosystem decline significantly in the last decade. To prevent further destruction of mangrove ecosystems due to human activities, conservation programs are needed. Therefore, information on mangrove's area as well as their distribution is needed. The main objective of this research was to demonstrate the ability of remote sensing and geographic information technology to provide reliable and accurate data on mangrove forest in Surabaya and thSidoarjo regions. A Landsat TM-5 imagery (acquisition date June 4 , 2009) data was utilized to produce the map. The results showed that in the 2009 period the area of mangrove forest in Surabaya and Sidoarjo was 378.19 Ha and 1236.42 Ha respectively. However, over 73.5% area of mangrove in Surabaya and 43.25% in Surabaya were under critical conditions. Anthropogenic factors and human influence were some of the main factors that cause the condition. Activities such as illegal and uncontrolled logging, conversion of mangrove's area and the lack of people's awareness in the importance of mangrove ecosystems were also problems that lead to the massive damage of mangrove forests.

Emission factors with increasing carbon dioxide (CO2) originating from various human activities are one of the causes of global climate change. The mangrove forest is a type of plant that has a great ability to absorb carbon in the atmosphere and store it in biomass through photosynthesis. Merauke Regency has 20 separate parts based on regional administration, but primary Mangrove forests are only found in ten regions (district). The results of research carried out using geographic information systems (GIS) in processing primary Mangrove forest data based on 2016 land cover map data in Merauke district, the area of primary mangrove forest reaches 184.402 ha, which is spread in various regions. With carbon deposits reaching 21 536 333 t ha-1-Carbon and Emission carbon dioxide reach 409 758.04 t ha-1.

Mangroves shelter coastlines during hazardous storm events with coastal communities experiencing mangrove deforestation are increasingly vulnerable to economic damages resulting from cyclones. To date, the benefits of mangroves in terms of protecting coastal areas have been estimated only through individual case studies of specific regions or countries. Using spatially referenced data and statistical methods, we track from 2000 to 2012 the impact of cyclones on economic activity in coastal regions inhabited by nearly 2,000 tropical and subtropical communities across 23 major mangrove-holding countries. We use nighttime luminosity to represent temporal trends in coastal economic activity and find that direct cyclone exposure typically results in permanent loss of 5.4–6.7 mo for a community with an average mangrove extent (6.3 m per meter of coastline); whereas, a community with more extensive mangroves (25.6 m per meter of coastline) experiences a loss equivalent to 2.6–5.5 mo. These results suggest that mangrove restoration efforts for protective benefits may be more cost effective, and mangrove deforestation more damaging, than previously thought.

The mahogany family, Meliaceae, contains 58 genera with only one mangrove genus: Xylocarpus. Two of the three species of the genus Xylocarpus are true mangroves (X. granatum and X. moluccensis), and one is a non-mangrove (X. rumphii). In order to resolve the phylogenetic relationship between the mangrove and non-mangrove species, we sequenced chloroplast genomes of these Xylocarpus species along with two non-mangrove species of the Meliaceae family (Carapa guianensis and Swietenia macrophylla) and compared the genome features and variations across the five species. The five Meliaceae species shared 130 genes (85 protein-coding genes, 37 tRNA, and eight rRNA) with identical direction and order, with a few variations in genes and intergenic spacers. The repetitive sequences identified in the rpl22 gene region only occurred in Xylocarpus, while the repetitive sequences in accD were found in X. moluccensis and X. rumphii. The TrnH-GUG and rpl32 gene regions and four non-coding gene regions showed high variabilities between X. granatum and the two non-mangrove species (S. macrophylla and C. guianensis). In addition, among the Xylocarpus species, only two genes (accD and clpP) showed positive selection. Carapa guianensis and S. macrophylla owned unique RNA editing sites. The above genes played an important role in acclimation to different stress factors like heat, low temperature, high UV light, and high salinity. Phylogenetic analysis with 22 species in the order Sapindales supported previous studies, which revealed that the non-mangrove species X. rumphii is closer to X. moluccensis than X. granatum. Overall, our results provided important insights into the variation of genetic structure and adaptation mechanism at interspecific (three Xylocarpus species) and intergeneric (mangrove and non-mangrove genera) levels.

Manguezais são formados por grupos de árvores e arbustos que se desenvolvem na zona de intermarés de regiões tropicais. Este ecossistema ao se estabelecer na interface do ambiente marinho e continental, apresenta sua formação relacionada com as flutuações relativas do nível do mar quaternário, através do preenchimento dos vales dos rios, margens de lagunas e baías com sedimentos tanto de origem continental como marinha. O conhecimento da distribuição de partículas e dos minerais constituintes da assembléia mineralógica dos solos em ambiente de planícies estuarinas, auxilia na compreensão de processos de sedimentação e geoquímica dentro dos estuários. O trabalho foi realizado nos manguezais distribuídos ao longo do litoral do Estado de São Paulo, e objetivou-se caracterizar os ambientes de sedimentação de acordo com a granulometria e o processo de evolução quaternária, determinar qualitativamente e semiquantitativamente a assembléia mineralógica e estudar em detalhe os tipos de esmectitas presentes nesses solos. Para tanto foram coletadas amostras de solos de 14 manguezais nas camadas de 0-20 e 60-80cm e de sedimento em suspensão do Rio Ribeira de Iguape, além de amostras de diferentes profundidades para datações. Determinaram-se as frações, argila, silte, areia total e 5 frações da areia, foram realizadas datações 14C por cintilação líquida e AMS na fração humina da matéria orgânica e por termoluminescência em grãos de quartzo. As análises mineralógicas foram realizadas na fração silte e argila e no sedimento em suspensão através de DRX, IV, MET, MEV com microanálise, ATD e ATG, realizou-se também o teste de Greene- Kelly para identificar o tipo de esmectitas presentes nesses solos. De acordo com os resultados obtidos, concluiu-se que os solos dos manguezais do Estado de São Paulo podem apresentar diferentes texturas desde arenosa até muito argilosa, freqüentemente contêm altos teores de silte e todos têm idade holocênica, oscilando entre 410 anos A.P. e 3.700 anos; a distribuição de partículas está relacionada à morfologia atual do estuário e à natureza dos sedimentos costeiros adjacentes; a assembléia mineralógica da fração fina dos solos é constituída de pirita, nontronita, caulinita, illita, gibbsita, quartzo, feldspato, e localmente ocorrem goethita, vermiculita, biotita, halloysita e anatásio; os minerais alóctones são de origem continental e marinha; a distinção entre os cenários geomorfológicos ao longo do litoral condiciona a distribuição de minerais, e ainda foi inferido que ocorre neoformação de esmectita e de caulinita, e que o processo de oxidação de matéria orgânica nesses solos pode estar utilizando o Fe3+ da nontronita como receptor de elétrons.
Mangroves are formed by groups of trees and shrubs that develop in the intertidal zone of tropical regions. This ecosystem to establish in the interface of both marine and continental environment, present its formation related to the sea-level fluctuations during the quaternary period, where the terrigenous and marine sediments are deposited in rivers valleys, edges of lagoons and bays. The knowledge of both particle distribution and minerals constituent of soils in estuarines areas, can aid to understand the processes of sedimentation and geochemistry in this site. This study was carried out with mangroves distributed along the São Paulo State coast, and aims to characterize the sedimentary environments in accordance with grain size and process of quaternary evolution, to determine qualitatively and semiquantitatively the mineralogical assemblage and to identify the smectites types in these soils. Samples were collected from 14 mangroves soils at the layers 0-20 and 60-80cm, and also was collected sediment in suspension of the Ribeira de Iguape River, and samples of different depths for dating. The clay, silt and total sand sizes and 5 sand fractions were determined, radiocarbon dating were carried out by liquid scintillation counting and accelerator mass spectrometry in humin fraction of the soil organic matter and by thermoluminescence of quartz grains. The mineralogical analyses were carried out by XRD, FTIR, TEM, SEM, DTA and GTA in silt and clay sizes and in the sediment in suspension, also was made the Greene-Kelly test to identify the smectites type. According to the results we concluded that the mangroves soils from São Paulo State have different textures varying from sandy up to very clay, also occuring high silt contents. All the mangroves are holocenic, with ages varying from 410 yr B.P. to 3,700 yr; the particle distribution is related to the current geomorphological setting of the estuary and the origin of coastal sediments. The mineralogical assemblage is constituted of pyrite, nontronite, kaolinite, illite, biotite, gibbsite, quartz, feldspars, and locally occurs goethite, vermiculite, halloysite and anatase; the aloctones minerals are from both the terrigenous and marine origin; the difference between geomorphological settings along the coastal plain rules mineral distribution, and still it was inferred the neoformation of esmectita and kaolinite and that the process of organic matter mineralization in these soils may be using Fe3+ from nontronite as an electron acceptor.

The book contains a biography of the oldest geologist in Ukraine. His homeland is the Chernihiv region, he lived in the Urals for about 30 years, worked and studied. The author was a participant in the Great Patriotic War as a tank crewman, fought in battles from Smolensk to Vienna (Austria). Since the 1960s he’s again been living in Ukraine. His biography reflects almost the entire Soviet era. The chapters of the book are imperceptibly interconnected by the original presentation of the material. Special attention is paid to the geology and mineralogy of deposits and ore occurrences of precious metals of the Urals, as well as the Carpathians and other regions of Ukraine.

Geoecology is a fruitful interdisciplinary field, relating rocks to soils to plant and animal communities and studying the interactions between them. Modern geoecology especially concentrates on showing how geology and soils affect the structure, composition, and distribution of plant communities in a certain research area. This book applies the principles of geoecology to Western North America, and to a specific kind of rock, the fascinating serpentine belts that run along the continental margins of the West Coast from Alaska to Baja. The authors come from different disciplines: Alexander is a soil scientist, Coleman a geologist, Harrison a biological researcher, and Keeler-Wolfe a vegetation ecologist. It begins with an overview of the geology of this rock and this region, covering mineralogy, petrology, and stratigraphy of West Coast serpentine. It will continue with serpentine soils and their development and distribution, and serpentine effects on plants and vegetation and animals. The serpentine geoecology of the different regions of Western North America, concentrating on California, will conclude the study. So, this academic book should appeal to plant ecologists, soil scientists, researchers in geoecology, and students in advanced courses in soil science.

AbstractAs a commune leading in movements of implementing climate change adaptive fisheries livelihood models associated with mangroves such as improved extensive shrimp farming and community-based mangrove management, Giao An has obtained great achievements in all three areas of the economy, society, and environment. Compared with similar models carried out in other regions, the models have created linkages for the development of production activities. The following sharing is expected to contribute more useful information and recommendations for the livelihood development of the study site as well as to be a source of reference for areas with the same conditions.

AbstractPotassium (K) outputs comprise removals in harvested crops and losses via a number of pathways. No specific environmental issues arise from K losses to the wider environment, and so they have received little attention. Nevertheless, K is very soluble and so can be leached to depth or to surface waters. Also, because K is bound to clays and organic materials, and adsorbed K is mostly associated with fine soil particles, it can be eroded with particulate material in runoff water and by strong winds. It can also be lost when crop residues are burned in the open. Losses represent a potential economic cost to farmers and reduce soil nutritional status for plant growth. The pathways of loss and their relative importance can be related to: (a) the general characteristics of the agricultural ecosystem (tropical or temperate regions, cropping or grazing, tillage management, interactions with other nutrients such as nitrogen); (b) the specific characteristics of the agricultural ecosystem such as soil mineralogy, texture, initial soil K status, sources of K applied (organic, inorganic), and rates and timing of fertilizer applications. This chapter provides an overview of the main factors affecting K removals in crops and losses through runoff, leaching, erosion, and open burning.

In this chapter, we present the recent progress in the experimental studies of the electrical conductivity of dominant nominally anhydrous minerals in the upper mantle of the deep Earth interior, namely, olivine, pyroxene, and garnet. The influences from pressure, oxygen partial pressure, and anisotropic orientation on hydrous and anhydrous electrical conductivities of minerals and rocks have been already explored detailedly. There are two main electric conduction mechanisms in Fe-bearing mantle minerals, for example, small proton and proton hopping conditions, which are well distinguished by the magnitude of activation enthalpy at high temperature and high pressure. Likewise, the conduction mechanisms are efficiently characterized by these obtained positive and negative effects from the oxygen fugacity on electrical conductivities of corresponding dry and wet Fe-bearing silicate minerals at the regions of the upper mantle under conditions of different oxygen partial pressures. On the base of high-pressure laboratory-based conductivity measurements for these nominally anhydrous minerals (e.g., olivine, pyroxene, and garnet), the water content will be estimated within the depth range of the upper mantle. In comprehensive considerations of filed geophysical magnetotelluric results, the electrical conductivity measurements of dominant upper-mantle minerals can thoroughly disclose the distribution, storage state, and migration conduction in the deep Earth interior.

Fish assemblages as reflected from coastal land use in mangrove estuary of Ban Laem District, Phetchaburi Province, Inner Gulf of Thailand had been conducted seasonally during December 2012 and October 2013. Samplings were conducted in blood cockle farms, public benefit channel, mangrove fringe area and Ban Laem estuary, using a push net at both day and night. A total of 29,287 individuals belonging to 11 orders 33 families and 54 species were collected. The Carangidae was by far the most speciose (6 species), with Arius maculatus numerically dominating (15,989 individuals, 54.59%). The highest number of individual was recorded in mangrove fringe area (21,051 individuals, 71.88%) in May (18,642 individuals, 63.65%) at day catches (22,149 individuals, 75.63%). The highest value indices of diversity, richness and evenness were 2.59, 3.65 and 0.88 respectively, recorded in mangrove fringe area in October. ANOSIM analysis showed a clearly significant difference of species compositions and abundance among sites, seasons and between day and night (p=0.001). Catches consisted primarily of juveniles or small-sized fishes, indicating that the area is important as a nursery ground. The findings of this study have implications for the conservation and management of mangrove and fisheries resources in Ban Laem and adjacent areas in the inner Gulf of Thailand.

The delta land Bangladesh has a unique coastline where numerous rivers meet the Bay of Bengal, creates a complex net of tidal river estuaries, forming the base for world’s largest mangrove forest the Sundarbans. Chalna is small town located at the confluence of Rupsha and Chunkuri rivers, only 9 km north of the Sundarbans, and a well know river port. The Sundarbans, which acts as a buffer between the sea and the human habitats including arable lands. The forest is rich in unique biodiversity and natural resources providing livelihoods of a large number of people living in the towns and villages around it. As the region is near the sea and land morphology is plain and of low altitude it is always vulnerable to natural disasters. Due to global warming and sea level rising the land mass is vulnerable to flooding. The sign of climate change; erratic behavior of rainfall and draught, intrusion of salinity etc., are changing the usual pattern of agriculture and fishing, affecting the livelihoods of the people here. The eco system of this mangrove forest is also threatened by recent policies of the Government and initiatives of private sectors of establishing high risk industrial establishments like thermal power plant, liquid petroleum gas stations etc., around Chalna and its surrounding region in sprawling manner. The potential of running large number of vessels through the rivers and canals of the Sundarbans might have negative impacts of the flora and fauna living there. Popular protests against these harmful interventions are being observed, international public organizations and concerned learned societies are also recommending not let these damaging developments going on. Although there are some promises from the government to the international agencies, there is no sign of management of such developments. This paper systematically investigates the reasons of this phenomenon, identifies the challenges and concludes that; absence of regional spatial planning in Bangladesh, neglecting the values of environment and public goods, defying the regulations in various ways and not accounting public opinions in the decision making process are the core ones.

A brief overview of the coastal biodiversity of Vietnam based on surveys conducted by the A.V. Zhirmunsky Institute of Marine Biology, Far Eastern Branch of the Russian Academy of Sciences for last 35 years. Main problems related to threats to biodiversity are discussed on the example of the intertidal communities, coral reefs, and molluscan diversity. Threats to marine biodiversity in Vietnam are summarized as follows: habitat degradation, fragmentation and loss (especially important are mangrove forest destruction, loss of coral reefs, change in landscape mosaic of wetland, estuary, sand and mud flats); global climate change including sea level rise, storm events, rainfall pattern change, warming of the coastal ocean; effects of fishing and other forms of overexploitation; pollution and marine litter; species introduction/invasions; physical alterations of coasts; tourism. Consolidated data of Vietnamese and Russian researchers on biodiversity and coastal zone management can be used in interpretations of ecosystem changes and for development of recommendations for local/national decision-makers.

Blue Carbon, which is carbon captured by marine organisms, has recently come into focus as an important factor for climate change initiatives. This carbon is stored in vegetated coastal ecosystems, specifically mangrove forests, seagrass beds and salt marshes. The recognition of the C sequestration value of vegetated coastal ecosystems provides a strong argument for their protection and restoration. Therefore, it is necessary to improve scientific understanding of the mechanisms that stock control C in these ecosystems. However, the contribution of Blue Carbon sequestration to atmospheric CO2 in shallow waters is as yet unclear, since investigations and analysis technology are ongoing. In this study, Blue Carbon sinks by Zostera marina were evaluated in artificial (Gotenba) and natural (Matsunase) Zostera beds in Ise Bay, Japan. 12-hour continuous in situ photosynthesis and oxygen consumption measurements were performed in both areas by using chambers in light and dark conditions. The production and dead amount of Zostera marina shoots were estimated by standing stock measurements every month. It is estimated that the amount of carbon storage as Blue Carbon was 237g-C/m2/year and 197g-C/m2/year in the artificial and natural Zostera marina beds, respectively. These results indicated that Zostera marina plays a role towards sinking Blue Carbon.

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%.
