Full textAbstract:
Management of powerline corridors in Australia has traditionally focused on the complete removal of vegetation using short rotation times owing to the perceived hazard of fire associated with corridor vegetation. Because of the intense management associated with fire hazards, little thought has been given to use of powerline corridors by wildlife. This has resulted in corridors traditionally being viewed as a source of fragmentation and habitat loss within forested ecosystems. We investigated the responses of small mammal communities living in a powerline corridor to management-induced vegetation changes at different successional stages, to determine whether a compromise could be reached between managing corridors for fire and biodiversity. Habitat modelling in the corridor and adjacent forest for three native and one introduced small mammal species demonstrated that species responded to changes in vegetation structural complexity, rather than time-since-management per se. Early seral stages of vegetation recovery after corridor management encouraged the introduced house mouse (Mus domesticus) into corridors and contributed little to biodiversity. Mid-seral-stage vegetation, however, provided habitat for native species that were rare in adjacent forest habitats. As the structural complexity of the vegetation increased, the small mammal community became similar to that of the forest so that corridor vegetation contributed fewer biodiversity benefits while posing an unacceptable fire risk. If ecologically sensitive management regimes are implemented to encourage mid-seral vegetation and avoid complete vegetation removal, powerline corridors have the potential to improve biodiversity. This would maintain landscape connectivity and provide habitat for native species uncommon in the forest while still limiting fuel loads in the corridor.

With the new round of western development being pushed forward and territorial spatial planning being put into place, northwest China’s urbanization rate has sped up. Urbanization will inevitably affect the city’s general landscape pattern and features, aggravating the landscape’s fragmentation and destroying the urban ecological environment. That threatens the well-being of the residents and the city’s biodiversity. Urban green space provides a habitat for the creatures in the city, and its connectivity provides corridors. Researchers and planners have developed green space networks to protect urban biodiversity and satisfy urban residents’ needs for recreation and ecologically friendly open space. This study uses RS, GIS, SeNtinel Application Platform (SNAP), and Conefor Sensinode. Applying the landscape connectivity index, least-cost path model, and corridor curvature analysis to identify potential recreation and biodiversity conservation corridors with a reasonable width, identifies good quality green space patches and corridors, or which ones need improvement. The results show that: (1) The patches selected by the possible connectivity index (PC) calculated with a threshold of 100 m in the urban area of Kashgar have higher recreational attributes. (2) There are 24 effective recreational corridors in Kashgar, with a total length of 43.44 km, and 53 effective biodiversity conservation corridors, a total of 78.23 km. Suppose recreational and ecological functions are considered to build a comprehensive green space network. The 50 m recreational corridor is mainly distributed in the center, and the 30 m biodiversity conservation corridor is primarily distributed on edge. (3) We can determine the location of the new green space suitable for protection or development by analyzing the corridor curvature. Through the constructed green space network, we can find that green space planning has severe fragmentation, unfair distribution, and other problems. Based on these issues, optimizing urban green space can promote the connectivity of urban green space. Furthermore, studying the width of corridors suitable for dense urban areas is conducive to protecting urban biodiversity and resident well-being.

Abstract. In biodiversity conservation, ecological corridors are assumed to increase landscape-level connectivity and to enhance the viability of otherwise isolated wildlife populations. Mapping these corridors serves as a feasible method to support forest management efforts in pinpointing areas to give special attention to. Here, we assess the current forest presence in the 3,000 hectare Mt. Lantoy, Key Biodiversity Area in Argao, Cebu and present potential forest corridors that could enhance the canopy cover of the current protected area. We present a method to map the potential corridors through the identification of the forest patches obtained from the global forest cover dataset and the creation of a species distribution model for the black shama, an endemic bird species in Cebu island and a great biodiversity indicator for the area. Our ecological corridors were acquired through the sum of the cost distance rasters obtained from the weighted overlay and cost surface tools of the black shama habitat suitability model. With the obtained corridors from the study, four potential forest corridors/ extensions were identified connecting five different forest patches. These corridors have areas that range from 0.47–2.17 square kilometers, with a potential to increase the forest cover in the KBA to more than 33% after corridor modelling.

Full textAbstract:
Conservationists are calling for bold strategies to connect wildlands and halt extinctions. A growing number of scientists recommend that 50% of all land must be held in a protected area network to maintain biodiversity. We assessed lands adjacent to the Pacific Crest Trail (PCT) and Continental Divide Trail (CDT) as possible wildlife corridors connecting protected areas in the American West. We evaluated the connectivity, wildness, and biodiversity values of the lands of each corridor and determined the conservation and land management status. We found that our corridors connect 95 protected areas creating two linear protected area chains from Mexico to Canada. Both the PCT and CDT corridors follow many of the best corridor routes previously found in the literature and hold high wildland conservation values. The American public already owns the majority of land units around the modeled PCT (88%) and CDT (90%) corridor. Therefore, we recommend further analysis of the lands adjacent to recreational trails as wildlife corridors. Employing our methodology on multiple scales could reveal that other recreational trails should be buffered and conserved for wildlife movement.

Electric powerline corridors are informal green spaces that encompass large areas of land and have the potential to support biodiversity in urban and suburban landscapes. However, the extent to which these corridors provide novel habitats compared to the surrounding landscape is unclear. Biodiversity in corridors is often compared to that of “natural” habitats despite the fact that the corridors are subject to frequent vegetation management. In urban and suburban landscapes, residential yards may provide a more appropriate comparison because they are a dominant type of green space and are also characterized by frequent vegetation management. We conducted a study of the biodiversity in suburban powerline corridors in northern Illinois, USA, and compared it to the biodiversity found in nearby residential yards. Our goal was to determine whether powerline corridors added ecological value to these suburban landscapes. We included three different management styles of powerline corridors: (1) frequently mowed and kept as lawn, (2) brush mowed on a five-year cycle (“old-field”), and (3) restored and/or maintained as native prairie. We measured the species richness and composition of plants, birds, and insect pollinators in corridors and yards. The corridor management types and comparison yards differed significantly in the richness of all three taxa, with old-field and/or prairie sites having greater species richness than mown corridors and/or comparison yards. Community composition also differed by management category. While the species richness of old-field sites tended to be high, prairie sites generally had more species of conservation interest. Our study shows that both old-field- and prairie-managed powerline corridors add habitat value to Midwestern U.S. suburban landscapes by providing alternative habitat types that support many species. Nonetheless, we suggest that managers looking to specifically support native and/or grassland specialist species in this region should manage sites as prairies when possible.

Biological habitat islanding occurs with the expansion of human activities. Nature reserves are biodiversity hotspots and sources of biodiversity diffusion. To explore the geographical causes of biodiversity and the impact of habitat island on biodiversity, we studied the spatial network relationships of biodiversity in nature reserves and the spatial characteristics of ecological corridors in reserves using various biodiversity indicators and ecological factors of important nature reserves, digital elevation models, and information regarding the land use types in Guizhou Province. Data were analyzed using canonical correspondence analysis and the lowest-cost analysis method. The results of this study showed that the factors that determine the biodiversity of the dominant region are heat, moisture, rock type, parent rock, and soil type. The nature reserves can be divided into seven categories according to the characteristics and ecological factors of the biodiversity network. We identified ecological corridors for biodiversity diffusion and classified them by levels of importance according to their degree of corridor composition.

Mediterranean central Chile is globally recognized as a hotspot for terrestrial biodiversity due to its high endemism and massive habitat loss. However, within the rural landscape of central Chile, significant extents of natural areas remain, especially on less productive, steep slopes, and vegetation strips extending from the surrounding hills to agricultural areas. Accordingly, vegetation strips or corridors, within lowland farms, constitute key elements to support the conservation of biodiversity in rural landscapes. To assess the ecological performance of corridors in 22 commercials vineyards in central Chile, we characterized them in terms of width-, length-, area-, and perimeter-to-area ratios, as well as the number of connections with natural areas. Based on a set of previously defined ecological indicators (species, functional groups, and structural components), we compared their occurrence in corridors within vineyards and in the surrounding natural areas. We evaluated the effects of corridor attributes on the occurrence of the selected ecological indicators, using a generalized linear mixed model with each vineyard as a random factor. The area, width, and length of vegetation corridors varied widely (1.2–86.3 ha, 10.5–95 m, and 380–5000 m, respectively). We found significant differences in the occurrence of indicators between corridors and natural areas. All sampled ecological indicators in corridors showed a negative relationship with the distance to the nearest natural area. Vegetation strips within vineyards represent important opportunities for biodiversity conservation that significantly enhance habitat quality in the agricultural landscape for biodiversity and habitat connectivity.

Thesis (MSc)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Habitat loss and fragmentation are major threats to global biodiversity. A cornerstone of traditional conservation involves setting aside land as formally protected areas (PAs). However, for effective biological conservation in the long term there needs to be connectivity between these PAs. When possible, improved connectivity can be achieved using natural corridors at a landscape scale. Even better is to establish a network of corridors and nodes in the form of ecological networks (ENs). ENs are currently being employed by commercial forestry companies in South Africa. While larger corridors and nodes are considered optimum, factors other than design, such as management and environmental heterogeneity, have also been found to be important for species maintenance. This study aims to explore the role of corridor width in driving the composition of invertebrate assemblages across a transformed landscape in KwaZulu-Natal, South Africa, and to investigate other possible environmental variables significant for species distributions. In Chapter 2, I investigated the contribution of smaller grassland corridors within a timber production matrix to overall biodiversity conservation using two important bioindicator taxa. Ants and dung beetles were sampled in grassland corridors of three size classes, plantation blocks and a nearby PA, iMpendle Nature Reserve. The two taxa showed differential responses to landscape level fragmentation. Dung beetles showed a decrease in species richness and corresponding increase in species turnover with increased fragmentation, while ants were unaffected, although counter intuitively smaller corridors even contained more unique ant species compared to larger corridors. Dung beetle assemblages also showed strong differences between the PA and grassland corridors. While the conservation effectiveness of large corridors undoubtedly exceeds that of smaller corridors, for ants it seems that smaller corridors contribute to their overall conservation within this production landscape. In Chapter 3, I explore the importance of spatial and environmental factors for species distribution across this landscape. Dung beetles were split into functional guilds according to size and nesting behaviour for analyses. Within grassland corridors, tunnelling dung beetle species richness was sensitive to landscape level fragmentation, especially for larger species, while elevation and vegetation type influenced ant species richness. Since rolling dung beetles showed a close association with the PA, the marked difference in dung beetle assemblages between these two land-uses may be due to the presence of pellet producing grazers in the protected area and their replacement by pat producing cattle in the grassland corridors. Other environmental variables that were found to be important for dung beetle species composition were elevation, vegetation type, and soil hardness. For ant species composition, only elevation was found to be important. In conclusion, as large corridors were comparable to the PA in dung beetle and ant species richness, ENs act as extensions of formally PAs, given that they are large enough. Nevertheless, smaller corridors had surprisingly high species richness. Including additional information other than species data improved our knowledge of the underlying factors that drive dung beetle species composition. Even though dung beetle and ant species responded differentially to habitat fragmentation, environmental heterogeneity seemed important for both taxa. Incorporating habitat heterogeneity into the current management scheme may improve the conservation effectiveness within this transformed landscape.
AFRIKAANSE OPSOMMING: Die vermindering en fragmentasie van natuurlike habitat is ‘n groot bedreiging vir globale biodiversiteit. ‘n Belangrike tradisionele benadering tot natuurbewaring behels die afbakening van land vir formele beskermde areas (BAs). Ten einde effektiewe biologiese bewaring oor die langtermyn te verseker moet daar verbinding wees tussen hierdie BAs. Indien moontlik kan verbeterde verbinding verkry word deur die gebruik van natuurlike gange op ʼn landskaps-vlak. Nog beter is om ʼn netwerk van gange en nodes in die vorm van ekologies netwerke (ENe) saam te stel. ENe word tans deur kommersiële bosboumaatskappye in Suid Afrika aangewend. Terwyl groter gange en nodes as optimaal beskou word, is ander faktore behalwe ontwerp, soos bestuur en omgewingsheterogeniteit, ook al gevind as belangrik vir die onderhouding van spesies. Hierdie studie is gemik daarop om die rol van gangwydte as dryfkrag vir die samestelling van invertebraatversamelings oor ʼn getransformeerde landskap in KwaZulu-Natal, Suid-Afrika, te ondersoek, asook ander moontlike omgewingsveranderlikes wat belangrik vir spesiesverpreidings kan wees. In Hoofstuk 2 het ek die bydrae van kleiner gange tot totale biodiversiteit-bewaring ondersoek deur twee belangrike bio-indikator taxa te bestudeer. Miere en miskruiers is versamel in grasland-gange van drie grootte-klasse, plantasie blokke en ‘n naby geleë BA, iMpendle Natuurreservaat. Die twee taxa het verskillende reaksies tot landskaps-vlak fragmentasie getoon. Miskruiers het ‘n verlaging in spesiesrykheid en ‘n gesamentlike verhoging in spesiesomset met verhoogde fragmentasie gewys, terwyl miere nie geaffekteer is nie, alhoewel kleiner gange het trouens meer unieke mierspesies bevat as groter gange. Die miskruierversamelings in die BA het ook opmerklik verskil van dié in die grasland-gange. Alhoewel die bewaringsdoeltreffendheid van groot gange beslis dié van kleiner gange oorskry, kom dit voor dat kleiner gange wel bydra tot die totale bewaring van miere binne hierdie produksielandskap. In Hoofstuk 3 het ek die belangrikheid van ruimtelike en omgewingsfaktore vir spesiesverspreiding oor hierdie landskap ondersoek. Miskruiers is ook in funksionele groepe verdeel volgens grootte en nes-gedrag vir aparte analise. Binne grasland-gange was tonnellende miskruierspesies sensitief vir landskaps-vlak fragmentasie, veral groter spesies, terwyl hoogte bo seevlak en vegetasie tipe mier spesiesrykheid beïnvloed het. Aangesien rollende miskruierspesies ‘n nabye assosiasie met die BA gewys het, mag die opmerklike verskil in miskruier versamelings tussen hierdie twee grondgebruike ʼn gevolg wees van die aanwesigheid van korrel-mis produserend beweiders in die BA en hulle vervanging deur nat-mis produserende beeste in die grasland-gange. Omgewingsveranderlikes uitsluitende ganggrootte wat belangrik gevind is vir miskruier spesiessamestelling was hoogte bo seevlak, vegetasie tipe en grond-hardheid. Vir mier spesiessamestelling was slegs hoogte bo seevlak belangrik. Om af te sluit, aangesien groot gange vergelykbaar was met die BA in miskruier en mier spesiesrykheid, tree ENe op as uitbreidings van BAs, mits hulle groot genoeg is. Desnieteenstaande het kleiner gange ‘n verbasende hoë spesiesrykheid gehad, veral onder miere. Die insluiting van addisionele inligting buiten spesiesdata het ons kennis van die onderliggende faktore wat miskruier spesiessamestelling dryf verbeter. Alhoewel miskruier- en mierspesies verskillend gereageer het op habitat fragmentasie, het dit voorgekom asof omgewingsheterogeniteit belangrik was vir die spesiesverspreiding van beide taxa. Die insluiting van habitatheterogeniteit binne die huidige bestuursplan mag die doeltreffendheid van bewaring binne hierdie getransformeerde landskap verbeter.

Full textAbstract:
Existing stresses of fragmentation on plant diversity and range dynamics will be exacerbated by climatic changes that shift bioclimatic regions northward. It is often stated that connectivity-enhancement through the establishment of corridors could facilitate the movement and conservation of plants, providing a timescale of dispersal and establishment relevant to rapid bioclimatic change. We tested this hypothesis focusing on forest herbaceous species dispersing through agroecosystems in southern Quebec using regenerating hedgerow-corridors. Thirty-one of forty-two species recorded in regional forests were also found in hedgerows, though species rates of dispersal through hedgerows, recorded at less than or equal to 2.50 meters per year, indicate corridors would not benefit the dispersal of these species in rapidly changing conditions. Forest species tend to reassemble in corridors with time, but our results suggest that establishing connectivity would only conserve agroecosystem plant diversity at long timescales; dispersal limitations and possibly environmental conditions represent a severe barrier for most species.Keywords: plant diversity, ecological corridor, climate change, fragmented landscape, connectivity, dispersal, conservation.Les tensions causées par la fragmentation sur la biodiversité et la distribution d'espèces seront exacerbées par les changements climatiques qui déplacent les régions bioclimatiques. L'amélioration de la connectivité grâce aux corridors faciliterait le mouvement et la conservation de la végétation en fournissant un délai de dispersion pertinent au changement climatique. Nous avons évalué cette hypothèse en nous concentrant sur les espèces herbacées forestières se dispersant au travers d'agroécosystèmes en utilisant des haies. Trente-et-une des quarante-deux espèces dans ces forêts ont été trouvées dans les haies, bien que les taux de dispersion au-travers des corridors, calculés sur l'année à moins de ou égal à 2.50 mètres, indiquent que les corridors ne favoriseraient pas la dispersion de ces espèces dans des conditions rapidement changeantes. Les espèces ont tendance à se rassembler dans les corridors, mais nos résultats suggèrent que la connectivité ne conserverait la diversité qu'à long-terme; les espèces sont limitées par la dispersion et possiblement par les conditions environnementales.Mots-clés: diversité végétale, corridor biologique, changements climatiques, fragmentation du paysage, connectivité, dispersion, conservation.

Mestrado em Gestão e Conservação de Recursos Naturais - Instituto Superior de AgronomiaThe Atlantic Forest is one of the biomes with the highest biodiversity in the world. Included among the 25 global hotspots due to its endemism, has today, 35% of plant species in Brazil, and many of these species are threatened with extinction. Compared to other countries and even other continents will, the biodiversity of the Atlantic Forest region is of global importance, being essential to their conservation. Brazil has the greatest diversity of World monkeys (48%), and, most endemic country, 2/3 of this amount occurring in the Atlantic Forest. Due to its wild habitat, have suffered great pressure by fragmentation in Atlantic Forest region, restricting habitats of populations to small fragments. The present study consists of a survey of presence and absence of Callithrix aurita, it is a species of primate rare, vulnerable and endemic Atlantic Forest. The importance of this survey is due to the current situation of the Atlantic Forest biome, particularly in the type of vegetation in the region studied, semideciduous forest, where there are the greatest deforestation for agricultural purposes and pasture due to climate, soil type, and other anthropogenic such as property market and building industries. Another factor that was considered is the presence of invasive species as Callithrix jacchus and Callithrix penicillata. The study was conducted in the state of Rio de Janeiro, the city of Sapucaia in the district of Vila Nossa Senhora Aparecida. We evaluated 11 fragments which registered the presence of Callithrix aurita in 8 of these fragments. To assist, we used the method play-back and questionnaires with residents and local workers. The council has a large agricultural exploration, and a total lack of environmental planning by local government. With the results of this survey, along with historical data collected, it was found that the municipality has a high environmental value. Even with the vulnerable status of the species, and its rarity, it is present in 70% of the fragments studied, and no record of invasive species, becoming fundamental to implementing a conservation plan, with the support of the public and society. The objective of this survey is to assist in defining priority areas for future creation of conservation units, using Callithrix aurita as flagship species, assisting in the work of environmental education and public awareness, exploring the potential tourist, historical, religious, among others the municipality for a better environment and a better quality of life for the region's population.

Full textAbstract:
Roads pose two central problems for wildlife: wildlife-vehicle collisions (WVCs) and habitat fragmentation. Wildlife exclusion fencing can reduce WVCs but can exacerbate fragmentation. In Chapter 1, I summarize the relevant studies addressing these two problems, with a focus on large mammals in North America. Chapters 2 and 3 summarize field assessments of technologies to reduce WVCs and maintain connectivity, specifically jumpout ramps and underpasses, along Highway 101 near San Luis Obispo, CA. In a fenced highway, some animals inevitably breach the fence and become trapped, which increases the risk of a wildlife-vehicle collision. Earthen escape ramps, or “jumpouts”, can allow the trapped animal to escape the highway corridor. Few studies have quantified wildlife use of jumpouts, and none for >2 years. We used wildlife cameras to quantify wildlife use of 4 jumpouts from 2012-2017. Mule deer were 88% percent of our detections and jumped out 20% of the time. After accounting for pseudoreplication, 33% of the events were independent events, and 2 groups of deer accounted for 41% of all detections at the top of the jumpout. Female deer were 86% of the detections and were much more likely than males to return to the jumpout multiple times. This is the first study to document use of jumpouts for more than 3 years, the first to account for pseudoreplication, and the first to quantify differences in jumpout use between male and female mule deer. We recommend a jumpout height between 1.75m-2m for mule deer to increase the jumpout success rate. Chapter 3 addresses factors that may affect the use of undercrossings by mule deer and other wildlife. Wildlife crossings combined with wildlife exclusion fencing have been shown to be the most effective method to reduce wildlife-vehicle collisions while maintaining ecological connectivity. Although several studies have quantified wildlife use of undercrossings, very few have exceeded 24 months, and the factors affecting carnivores use of the undercrossings remain unclear. We quantified mule deer, black bear, mountain lion, and bobcat use of 11 undercrossings along Highway 101 near San Luis Obispo, California from 2012-2017. We constructed zero-inflated Poisson general linear models on the monthly activity of our focal species using underpass dimensionality, distance to cover, substrate, human activity, and location relative to the wildlife exclusion fence as predictor variables. We accounted for temporal variation, as well as spatial variation by quantifying the landscape resistance near each undercrossing. We found that deer almost exclusively used the larger underpasses whereas the carnivores were considerably less selective. Bears used undercrossings more that were within the wildlife exclusion fence, whereas mountain lion activity was higher outside the wildlife exclusion fence. Bobcat activity was highest and most widespread, and was negatively associated with distance to cover. Regional connectivity is most important for bear and mountain lion, and the surrounding habitat may be the most important predictor for their use of undercrossings. We recommend placing GPS collars on our focal species to more clearly document fine-scale habitat selection near the highway.

Thesis (MSc)--Stellenbosch University, 2015.ENGLISH ABSTRACT: The ultimate goal of conservation planning is to ensure persistence of biodiversity. Biodiversity patterns and ecological processes are important aspects in conserving biodiversity. Although most researchers in conservation planning have focused on targeting biodiversity patterns, ecological and evolutionary processes can ensure persistence of biodiversity if incorporated into conservation planning. Ecological processes are the main drivers or sustainers of biodiversity. The aim of this research was to identify and map the spatial components of ecological processes in a portion of the Kavango Zambezi Transfrontier Conservation Area to aid in the implementation of biota movement corridors. Different methods have been used to identify suitable corridors but not much has been done on defining and mapping ecological processes that will ensure that the corridors maintain and generate biodiversity. A thorough literature survey was done to make a list of ecological processes that are important in maintaining the biodiversity in the area. Spatial components of ecological processes were mapped as surface elements aligned along linear environmental interfaces or gradients. The last part of the research was to suggest suitable movement corridors based on ecological processes. The results include five spatial components: riverine corridors, areas of high carbon sequestration, edaphic interfaces, upland-lowland interfaces and ecotones. Riverine corridors were mapped using a 1000 m buffer on either side of low lying rivers and 500 m buffer around rivers in the uplands. A map showing the carbon sequestration potential of vegetation in the study area was made using Moderate-Resolution Image Spectroradiometer (MODIS) derived NDVI data and the National Level Carbon Stock dataset done by the Woods Hole Research Center (WHRC) Pantropical. Edaphic interfaces were idenfied using by a 250 m buffer around contrasting soil types. Upland-lowland interfaces identified by a 250 m buffer along upland and lowland habitats. Classification of Landsat 8 was used to identify ecotones in the study area. The results of the spatial components were then compared with the habitat transformation map which shows populated areas.

Alhoewel die meeste navorsers in bewaringsbeplanning fokus op teiken biodiversiteitspatrone, kan die voortbestaan van ekologiese en evolusionêre prosesse van biodiversiteit verseker word deur insluiting in bewaringsbeplanning. Ekologiese prosesse is die belangrikste drywers, of onderhouers, van biodiversiteit. Die doel van hierdie navorsing was dus om die ruimtelike komponente van ekologiese prosesse in 'n gedeelte van die Kavango Zambezi oorgrensbewaringsgebied te identifiseer en te karteer om te help met implementering van biota bewegingsdeurlope. Verskillende metodes is al gebruik om gepaste deurlope te identifiseer, maar min navorsing is gedoen oor definisie en kartering van ekologiese prosesse om te verseker dat die deurlope biodiversiteit sal onderhou en genereer. 'n Deeglike literatuurstudie is gedoen om 'n lys op te stel van ekologiese prosesse wat belangrik is in die handhawing van biodiversiteit in die gebied. Ruimtelike komponente van ekologiese prosesse is gekarteer as oppervlak elemente gebonde aan lineêre omgewingskoppelvlakke of gradiënte. Die laaste deel van die navorsing was om geskikte bewegingsdeurlope, gebaseer op ekologiese prosesse, voor te stel. Die resultate sluit vyf ruimtelike komponente in: rivierdeurlope, gebiede van hoë koolstofsekwestrasie, edafiese koppelvlakke, hoogland-Laeveld koppelvlakke en grensekotone. Rivierdeurlope is gekarteer met behulp van 'n 1000 meter buffer aan weerskante van laagliggende riviere en 500 meter buffer rondom riviere in die hooglande. ‘n Kaart wat die koolstofsekwestrasiepotensiaal van plantegroei in die studie area toon is gemaak met behulp van Moderate-Resolution Image Spectroradiometer (MODIS) afgeleide NDVI data en ʼn koolstofvoorraaddatastel (National Level Carbon Stock dataset) voorsien deur die Woods Hole Research Center (WHRC). Pantropiese edafiese koppelvlakke is geïdentifiseer met behulp van 'n 250 meter buffer rondom kontrasterende grondtipes. Hoogland-Laeveld koppelvlakke is geïdentifiseer deur 'n 250 meter buffer langs die berg en laagland habitatte. Klassifikasie van Landsat 8 data is gebruik om ekotone in die studie area te identifiseer. Die resultate van die ruimtelike komponente is vergelyk met die habitattransformasiekaart wat bevolkte gebiede toon.

O presente trabalho objetivou na avaliação da sustentabilidade do Plano de Gestão do Corredor Ecológico Araguaia - Bananal, inserido na região do Médio Araguaia, entre os Estados de Goiás, Mato Grosso, Pará e Tocantins, cujo cenário de atuação compreende os domínios dos biomas Cerrado e Amazônia. Como instrumentos de avaliação, foram adotados os procedimentos metodológicos da Avaliação Ambiental Estratégica (AAE) proposto pelo Ministério do Meio Ambiente, por este permitir uma análise ampla e sistêmica da ação de Políticas-Planos-Programas (PPP) sobre uma determinada região ou enfoque setorial. Suas etapas de avaliação compreendem as fases descritas a seguir: Screening (Início – Sondagem), cuja função consistiu na exposição do plano, por meio da confirmação da possibilidade e da necessidade em se aplicar a AAE ao plano de gestão do corredor ecológico, em virtude do plano estar inserido em uma, região de grande relevância a conservação da biodiversidade, e por se tratar de uma ação de significativa intervenção regional. O seu grau estratégico conferiu-se neste caso em um plano regional de gestão territorial, onde sua atuação compreende principalmente o mosaico de Unidades de Conservação e as comunidades sob a influência da região. Foram expostas as principais forças motrizes que influenciam os impactos ao ambiente, caracterizadas pelas atividades agropecuárias, pela expansão populacional dos centros urbanos decorrente da concentração fundiária e êxodo rural, dos projetos de desenvolvimento para a logística de transporte e geração energética, e a pressão exercida pela reforma agrária. A etapa seguinte consistiu na definição do escopo (Scoping), cuja função inicial correspondeu na exposição do propósito do plano de gestão do corredor ecológico Araguaia - Bananal, sequenciado pela apresentação dos seus objetivos, os quais após uma análise de compatibilidade confirmaram o seu direcionamento com os objetivos de preconizados pela AGENDA 21 brasileira. Na identificação das Políticas, Planos e Programas (PPP), foram selecionados as que exercem influência na região do corredor ecológico, cujos objetivos passaram pela avaliação de compatibilidade frente os objetivos do plano de gestão, verificando-se a existência de diversos pontos conflitantes, em especial aos que estimulam o desenvolvimento agropecuário e ao setor de infraestrutura. Foram estabelecidos os principais indicadores de sustentabilidade e produção, totalizando 40 indicadores, que auxiliaram no processo de avaliação ambiental e desenvolvimento dos cenários, apoiado pelo modelo de fluxo causal DPSIR (Driving Forces – Pressures – State – Impacts - Response), permitindo identificar simultaneamente a presença de sete forças motrizes e 71 impactos ambientais. A conclusão obtida por este estudo aponta, para um plano de gestão que apresenta objetivos e ações que poderiam ter efetividade na sua aplicação, caso os indicadores levantados e seus cenários, não apontassem para uma realidade desfavorável, expressa pelo baixo grau de desenvolvimento socioeconômico da região, e ausência de conectividade nas ações da esfera pública, ocasionando a individualização da responsabilidade na solução da problemática de desenvolvimento social e da agenda ambiental.The present study aimed at assessing the sustainability of the Management Plan of the Ecological Corridor Araguaia - Banana plantation, inserted in the Middle Araguaia, between the states of Goiás, Mato Grosso, Pará and Tocantins, whose field of action covers the areas of the Cerrado and Amazon. Evaluation tools, we adopted the methodological procedures of Strategic Environmental Assessment (SEA) proposed by the Ministry of the Environment, by this permit analysis of broad and systemic action policies-Plans-Programs (PPP) over a particular region or sector focus. Their evaluation stages comprise the phases described below: Screening, whose function consisted in the exhibition of the plan, through the confirmation of the possibility and necessity to apply the SEA management plan ecological corridor, under plan to be inserted into a region of great importance to biodiversity conservation, and because it is an action of significant regional intervention. The degree conferred strategy in this case in a regional plan for land management, where its operations mainly comprises the mosaic of protected areas and communities under the influence of the region. Exposed were the main driving forces that influence the impacts to the environment, characterized by agricultural activities, the expansion of the urban population due to land concentration and rural exodus, development projects for the transportation logistics and power generation, and pressure for reform agrarian. The following stage consisted of the definition of Scoping, whose initial function ended up exposing the intention of the ecological corridor management plan Araguaia-Bananal, in its goals identification, which later confirmed to be compatible with the sustainable development goals praised by the Brazilian AGENDA 21. In the politics-plans–programs (PPP) identification, those that apply influence towards performance forces in the ecological corridor region had been chosen, whose goals had passed by the compatibility evaluation with the management plan goals, verifying itself the diverse conflicting points evaluation, in special to those that stimulate the farming development and the infrastructure sector. The main indicators of sustaintability and production had been established, totalizing 40 indicators, that had assisted the ambient evaluation process, where the adopted procedure used the causal flow DPSIR model, allowing simultaneously to identify the 7 driving forces performance and 71 environment impacts. The conclusion obtained by this study indicates to a management plan that has goals and actions that would be effective in its application, if the indicators surveyed and their scenarios, it pointed to a reality unfavorable expressed by the low level of socioeconomic development of the region and lack of connectivity in the actions of the public sphere, leading to the individualization of responsibility in solving the problems of social and environmental agenda.

Full textAbstract:
L’urbanisation est l’un des phénomènes majeurs qui impactent la biodiversité à l’échelle mondiale. Les nombreuses contraintes associées au milieu urbain (perte d’habitat, changement des ressources, pollutions chimique, lumineuse et sonore, etc.) modifient la diversité et la répartition des espèces animales, et peuvent avoir de lourdes conséquences à l’échelle individuelle. Or, le développement constant du milieu urbain nécessite de mettre à jour les études sur les effets de ce milieu sur les espèces animales, et en particulier sur les oiseaux, qui rendent de nombreux services écosystémiques à l’homme. Dans ce contexte, nous avons cherché à étudier les bénéfices et contraintes du milieu urbain chez les oiseaux, en se plaçant à trois échelles différentes : biodiversité, population et individu. Dans un premier temps, nous avons réalisé une étude spatiale de la biodiversité aviaire à Niort. Nous avons pu mettre en évidence l’importance de maintenir des infrastructures vertes et connectées en ville, pour favoriser la présence des espèces communes comme celles moins adaptées au milieu urbain. Dans un deuxième temps, nous avons cherché à évaluer l’état des populations de moineaux domestiques en ville, ceux-ci étant en fort déclin dans les grandes villes européennes. À l’aide d’une étude corrélative, nous avons démontré que le milieu urbain est particulièrement stressant pour les moineaux en développement. Également, l’analyse d’un stress hydrique en conditions expérimentales nous a permis de constater que les moineaux adultes sont également très sensibles aux changements des conditions de l’environnement. Dans un troisième temps, l’application d’une contrainte du milieu urbain (pollution lumineuse) sur les moineaux au cours de la reproduction a permis de mettre en évidence des changements rapides du comportement individuel en réponse à cette contrainte. Les résultats de ces différentes approches démontrent que les effets de l’urbanisation sur les oiseaux sont complexes, et que les suivis démographiques doivent être associés à des études précises de l’habitat urbain et des contraintes associées pour mieux comprendre l’évolution des populations d’oiseaux en villeUrbanization is one of major phenomena that impact biodiversity in the world. Numerous constraints associated with urban environment (habitat loss, changes in resources, chemical, light and noise pollutions, etc.) modify wildlife diversity and species distribution, and can have detrimental consequences on individuals. However, constant development of urbanization implies to update studies on the effects of urban environment on animal species, and particularly on birds, as they fulfill numerous ecosystem services for humans. In that context, we studied the benefits and costs of urban life for birds, working at three different levels: biodiversity, population and individual. First, we realized a spatial study on avian biodiversity in Niort (France). We highlighted the need to maintain green and connected infrastructures in cities, to favor common species as less adapted species to urban environment. Second, we evaluated the population state of house sparrows in cities, as they are strongly declining in large European cities. With the use of a correlative study, we showed that urban environment is very stressful for developing sparrows. Moreover, the analysis of osmotic stress in experimental conditions allowed to find that adult sparrows are also sensitive to changes of environmental conditions. Third, the application of a constraint of urban environment (light pollution) on house sparrows during reproduction revealed rapid changes in individual behavior in response to this constraint. Finally, results of these different approaches show that the effects of urbanization on birds are complex, and that demographic surveys need to be coupled with precise studies of urban habitat and associated constraints to better understand the evolution of bird populations in cities

Previous issue date: 2011-06-09The human pressures on natural environments generate fragmentation and loss of habitat, one of the main threats to biodiversity. Using the terrestrial mammals as indicators, it were evaluated the ecological corridor Embrapa- Fazenda Engenho Velho (Old Mill Farm) and a silvopastoral system to determine if they actually mitigate the negative impacts of local farming. Four linear transects were laid in two fragments of semideciduous forest in the ecological corridor that connects them and made 24 observations, including the branch tunnels (one with 0.9 m in diameter and another with 2.5 x2m) under the highway Guilherme Scatena (that divides the ecological corridor) and its coasting. With the data was constructed a dendrogram of similarity (Jaccard coefficient). In the silvopastoral system and conventional grazing, were placed four cages (15x15x40cm) in each and 20 observations were made. The results demonstrate the presence of 27 species in the fragments, seven of which use the corridor and only two uses the tunnel passage. The similarity between the fragments is high (65%), but decays over the corridor (44%) and the tunnel passage (19%), which shows that the ecological corridor is not fulfilling its role of facilitating the exchange of individuals among the fragments for greater genetic variability in local populations. Furthermore, the coasting had 11 species (45% similarity with fragments), but no individual was found run over, suggesting that in this case, the speed bumps installed on the highway are the most effective tools for conservation than the actual tunnel passage. The largest tunnel presented seven species, but lacks the vegetation in the surroundings unlike smaller tunnel, suggesting that for the branch tunnels, it is extremely important to their size. In the silvopastoral system were found four individuals from three genera (Calomys, Akodon and Oligorizomys) and in the common grazing, eight individuals of the genus Calomys, suggesting that silvopastoral systems are better to maintain species richness. We conclude that there are viable alternatives to improve production and maintain biodiversity, native vegetation with the best connection, but the deployments must be accomplished effectively and not only for law enforcement, without ever having a monitoring of its function, as occurs in most rural areas of the country subjected to this type of activity. Also we can t think that the mere fact of clearing vegetation and deploy these systems are solutions to the environmental crisis, but to optimize the use of land already cleared for such deployment.
As pressões antrópicas geram fragmentação nos ambientes naturais e consequente perda de habitat, uma das principais ameaças à biodiversidade. Utilizando a mastofauna terrestre como indicadores, foram avaliados o corredor ecológico Embrapa-Fazenda Engenho Velho e um sistema silvipastoril, para detectar se realmente mitigam os impactos negativos da agropecuária local. Foram dispostos quatro transectos lineares em dois fragmentos de floresta estacional semidecídua, no corredor ecológico que os conecta e feitas 24 observações, incluindo nos túneis de passagem (um de 0,9m de diâmetro e outro de 2,5x2m) sob a rodovia Guilherme Scatena (divide o corredor ecológico) e seu acostamento. Com os dados construiuse um dendrograma de similaridade (coeficiente de Jaccard). No sistema silvipastoril e em pastagem convencional foram dispostas quatro gaiolas (15x15x40cm) cada e foram feitas 20 observações. Os resultados demonstram a presença de 27 espécies nos fragmentos, das quais sete usam o corredor e somente duas o túnel de passagem. A similaridade entre os fragmentos é alta (65%), mas decai em relação os corredor (44%) e ao túnel de passagem (19%), o que demonstra que o corredor ecológico não está cumprindo seu papel de facilitar a permuta de indivíduos entre os fragmentos para que haja maior variabilidade genética nas populações locais. Além disso, o acostamento apresentou 11 espécies (45% de similaridade com os fragmentos), mas nenhum indivíduo foi encontrado atropelado, sugerindo que, neste caso, os redutores de velocidade instalados na rodovia são ferramentas mais eficazes para conservação do que o próprio túnel de passagem. O túnel maior apresentou sete espécies, mas não possui a vegetação no entorno como o túnel menor possui, sugerindo que, para túneis de passagem, é extremamente importante o seu tamanho. No sistema silvipastoril foram encontrados quatro indivíduos de três gêneros (Calomys, Akodon e Oligorizomys) e na pastagem comum, oito indivíduos do gênero Calomys, sugerindo que sistemas silvipastoris mantêm melhor a riqueza de espécies. Conclui-se que há alternativas viáveis para melhorar a produção e manter a biodiversidade, com a vegetação nativa melhor conectada, porém as implantações devem ser efetuadas de modo efetivo e não apenas para o cumprimento das leis, sem sequer haver um monitoramento de sua função, como ocorre na maioria das áreas rurais do país submetidas a esse tipo de atividade. Também não se deve pensar que o simples fato de desmatar e implantar esses sistemas são soluções para a crise ambiental, mas sim otimizar o uso de terras já desmatadas para tal implantação.

AbstractBiodiversity on Earth is rapidly decreasing and the situation in the Netherlands is in that perspective a textbook example. The main causes for species extinction are habitat loss, landscape degradation and overuse. Conservation efforts should focus more on the level of viable ecosystems. A strategic plan to do so is called Cores, Corridors and Carnivores (rewilding’s three C’s). This requires strong Cores of nature, mutually connected via robust Corridors. Based on island biogeography theory it can be calculated that if we want to conserve roughly 85% of the current biodiversity, 50% of the Earth’s surface needs to be protected, ‘Nature needs half’. For healthy ecosystems we need to get top-down forcing by apex consumers back in ecosystems. These apex consumers are mainly large Carnivores, and bringing them back asks for coexistence. If we want to keep our living conditions on planet Earth healthy we have to change our unsustainable way of living and change our way of thinking with respect to nature, natural processes and our relation with other species. The loss of biodiversity can only be halted or reversed if we save more space for nature and natural processes including top-down forcing and last but not least, find a way of coexistence with our fellow creatures.

Full textAbstract:
“Sustainable Development” is now a widely accepted concept, yet there are surprisingly few concrete examples of it in practice. The pipeline industry operates at broad landscape and regional levels, and now has the opportunity to provide a strong lead in showcasing how society can benefit from major new energy pipelines while not significantly compromising natural and cultural values. To achieve this requires adoption of a fundamental proactive, ecosystem-based principle — the “Conservation First Principle”. In Canada this principle, first stated by Hummel [1], is that “there should be no new or expanded large-scale industrial development until a network of protected areas is reserved which adequately represents the natural region(s) affected by that development”. This approach is not new (e.g., the 1992 commitment by all levels of Canada’s governments to complete such protected areas networks), but it is more urgently needed now in an energy-rich frontier nation like Canada to truly safeguard our natural and cultural values while developing new energy corridors. It is a precautionary approach, akin to an insurance policy we would all be familiar with at a personal level. By identifying key natural habitats in each natural region (areas of similar bio-physical characteristics — there are 486 terrestrial natural regions in Canada), and using sophisticated GIS-based gap analysis, working with local communities, industry and governments, a network of protected areas can be identified and then reserved for legal protection. This network then adequately protects a representative sample of habitats, biodiversity and ecosystem processes in each natural region before or simultaneous with development proposals and approvals. The development of natural gas reserves in the Mackenzie Valley provides all stakeholders with a timely high-profile opportunity to showcase this balanced approach. The NWT’s Protected Areas Strategy provides the widely-supported community-led process to identify and then reserve key cultural and ecological areas in tandem with gas pipeline development. Investors, industry, governments, local communities and the general public all seek the greater certainty and security that such advance planning and balancing provides. The knowledge that certain key areas are off-limits to future development, and that other areas (the largest portion of each natural region) are assigned for sensitive industrial development, sets the stage for a more secure, stable future, in which all values are accommodated satisfactorily. In the push for greater energy security, the pipeline and oil and gas industry should now embrace the Conservation First Principle in energy developments across Canada’s lands and oceans, most immediately as it plans for a major gas pipeline in the Mackenzie Valley.

Perkins, Dustin. Invasive exotic plant monitoring at Dinosaur National Monument: Results of the 2019 field season on the Green River, and the third completed monitoring rotation. Edited by Alice Wondrak Biel. National Park Service, December 2021. http://dx.doi.org/10.36967/nrr-2284627.
Full textAbstract:
Invasive exotic plant (IEP) species are a significant threat to natural ecosystem integrity and biodiversity, and controlling them is a high priority for the National Park Service. The Northern Colorado Plateau Network (NCPN) selected the early detection of IEPs as one of 11 monitoring protocols to be implemented as part of its long-term monitoring program. We also calculated a patch management index (PMI) to quantify the extent and density of invasive patches into a single value that helps identify the scale of the problem. Park managers can use this tool to help prioritize IEP treatment. At Dinosaur National Monument, the NCPN monitors IEPs in the Green and Yampa river corridors. This report summarizes data from monitoring on the Green River in 2019, and monitoring on the Yampa River in 2017, to represent the completion of the third monitoring rotation of the entire river corridor (2002–2005, 2010–2011, 2017–2019). During surveys conducted from June 26 to July 2, 2019, NCPN staff detected 12 priority IEP species and two non-priority species in a 84.6-hectare (209-acre) area along 74.4 kilometers of the Green River above (“upper”) and below (“low-er”) its confluence with the Yampa. A total of 2,535 IEP patches were detected. Of those patches, 24.2% and 15.6% were smaller than 40 m2 on the upper and lower Green River reaches, respectively. The patch management index (PMI) was low or very low for 95.7% of patches on the upper Green River and 90.9% of patches on the lower Green River. Tamarisk (Tamarix sp.), broad-leaf pepperwort (Lepidium latifolium), and yellow sweetclover (Meli-lotus officinalis) were the most widespread species. For the first time, NCPN monitoring detected teasel (Dipsacus sylvestris) on the upper Green River. Yellow sweetclover has increased on all three river reaches during the survey years. Musk thistle (Carduus nutans) was found at considerably lower levels than yellow sweetclover but has also increased on all three river reaches. Leafy spurge is increasing on the lower Green River and Yampa River. Cheatgrass was not monitored in the first rotation, but increased substantially in cover and percent frequency on all three river sections from 2010–2011 to 2017–2019. This increase may be due to a lack of recent high-flow scouring events. The highly regulated upper Green River generally has the highest number of IEPs, while the lower Green River has a moderate amount of IEPs. The largely unregulated flows of the Yampa River continue to result in a lower number of patches per kilometer, lower percent cover, and lower percent frequency than the upper or lower Green River. Network staff will return to the monument in 2022 to begin the fourth monitoring rotation.
