“…In sharp contrast, the USFWS at the STRC has a clear plan to establish five wildlife corridors with viable connections of key protected habitats in the United States and Mexico. Well-defined goals of corridors need to be expressed in the context of six ecological functions that can be very species specific; a corridor can represent a conduit, a habitat, a filter, a barrier, a source, and (or) a sink, or a combination depending on its dimensions, location, and habitat quality (Hess and Fischer, 2001). A recent meta-analysis of 35 studies demonstrated that movement of organisms increased about 50 percent between habitats connected by corridors; movements were more evident for plants, invertebrates, and nonbird vertebrates than for bird species (Gilbert-Norton and others, 2010).…”

AbstractThe Lower Rio Grande Valley (LRGV) of southern Texas is located on the United States-Mexico borderland and represents a 240-kilometer (150-mile) linear stretch that ends at the Gulf of Mexico. The LRGV represents a unique transition between temperate and tropical conditions and,

“…Son intérêt vient: (a) de l'impossibilité d'étendre le système de grands parcs à tout le territoire, (b) de la pertinence d'établir des réseaux écologiques qui permettent la complémentarité des écosystèmes différents (Forman & Godron, 1986;Hess & Fischer, 2001), (c) de la réduction de la vulnérabilité des différentes réserves du réseau aux catastrophes naturelles (Carrière et al, 2008). Plus précisément, cette stratégie tient compte du fait que: (a) certaines espèces ne peuvent survivre que dans une seule et importante réserve dont la fragmentation réduirait fortement leur potentiel d'adaptation, (b) un réseau d'habitat permettrait atténuer l'extinction des espèces en permettant de recoloniser des parcelles vides par la migration (Hess & Fischer, 2001;Ovaskainen, 2002 (Carrière et al, 2008, p. 102-103).…”

La place de la biodiversité dans les documents de planification urbaine en France

Resumé La prise de conscience par les acteurs sociaux et politiques des enjeux environnementaux et de la nécessité de conservation de la biodiversité va conduire à de nouvelles politiques et à l'utilisation d’outils de planification territoriale novateurs comme le Schéma de Cohérence Territorial (SCoT). Le SCoT est l’instrument central de l’aménagement communautaire urbain français, qui associe le rôle d’assemblage de plusieurs politiques sectorielles et de coordination multi-scalaire aux objectifs de conception de villes durables. Il est donc souhaité que les SCoTs soient capables: (a) d’améliorer les procédures d’aménagement par l’instauration de territoires de planification mieux adaptés aux enjeux, (b) d’élargir le dialogue entre acteurs et société civile et (c) d’agir pour la “soutenabilité” des villes. Nous nous interrogeons ici sur la prise en compte de la biodiversité dans les stratégies et prescriptions mises en place par les SCoTs de la Communauté d’Agglomération de Montpellier et de la Région Urbaine Grenobloise. A partir d’une analyse empirique, nous prétendons identifier les stratégies prescrites et les limites de ces documents d’urbanisme en ce qui concerne ces stratégies et leur application, la pertinence des périmètres de projet et d’action.

“…In addition, surrounding landscape structure, such as the presence of forest patches and isolated trees, can promote the arrival of seeds in hedgerows (Harvey 2000). Hess & Fischer (2001) have suggested that corridors can serve as conduits, barriers, or habitats, among other functions. Propagules of some animal-dispersed species may be deposited in the corridor, indicating that seed dispersal may not reach the ends of long corridors; thus such plant species must establish and reproduce within the corridor to complete dispersal in subsequent generations (Beier & Loe 1992).…”

Plant diversity in hedgerows amidst Atlantic Forest fragments

et al. 2015

View full text Add to dashboard Cite

Hedgerows are linear structures found in agricultural landscapes that may facilitate dispersal of plants and animals and also serve as habitat. The aim of this study was to investigate the relationships among diversity and ecological traits of woody plants, hedgerow characteristics (size, age, and origin), and the structure of the surrounding Atlantic Forest landscape. Field data were collected from 14 hedgerows, and landscape metrics from 1000-m buffers surrounding hedgerows were recorded from a thematic map. In all sampled hedgerows, arboreal species were predominantly zoochoric and early-succession species, and hedgerow width was an important factor explaining the richness and abundance of this group of species. Connection with forest vegetation did not explain richness and abundance of animal-dispersed species, but richness of non-zoochoric species increased in more connected hedgerows. These results suggest that hedgerows are probably colonized by species arriving from nearby early-succession sites, forest fragment edges, and isolated trees in the matrix. Nonetheless, hedgerows provide resources for frugivorous animals and influence landscape connectivity, highlighting the importance of these elements in the conservation of biodiversity in fragmented and rural landscapes.
