The fragmenting of habitats is endangering animal populations and degrading or destroying many plant populations in the course of the international. to deal with this challenge, conservationists have more and more grew to become to organic corridors, parts of land put aside to facilitate the move of species and ecological procedures. although, whereas thousands of hall projects are less than means around the globe, there's little useful info to steer their layout, position, and administration. Applying Nature's Design deals a entire review of present wisdom on corridors, their layout, and their implementation. Anthony B. Anderson and Clinton N. Jenkins study quite a few conceptual and functional concerns linked to corridors and supply targeted case reports from all over the world. Their paintings considers easy methods to deal with and govern corridors, find out how to construct help between numerous curiosity teams for corridors, and the hindrances to implementation. as well as assessing a number of environmental and ecological demanding situations, the authors are the 1st to contemplate the significance of socioeconomic and political concerns in growing and keeping corridors.

Sample text

A Beier (1993) suggests that the cougar is a particularly useful focal species because its extensive nightly movements allow corridor routes to be mapped relatively quickly. b Protecting Communities and Ecosystems While corridor design often revolves around focal species, it is important to understand that this approach does not guarantee protection of the full range of species and habitats of conservation interest. For example, in the Y2Y Corridor scientists found that corridors designed to serve grizzly bears in the Swan Valley of Montana would fail to protect key habitat for endangered bull trout (Wuethrich 2000).

Ecoregions provide a useful conceptual framework and scale for identifying priorities for biodiversity conservation, defining appropriate interventions, and monitoring their impact. In contrast, corridors represent one kind of conservation intervention. In practice, corridors are generally smaller than ecoregions, although in some cases—such as the Yellowstone to Yukon (Y2Y) Corridor and the Mesoamerican Biological Corridor—landscape corridors may exceed ecoregions in extent. 1 summarizes the definitions, objectives, and approaches to implementation of linear and landscape corridors and gives examples of each.

2. a continued Corridor Design 33 • To determine a minimum corridor width for maintaining connectivity between upland and lowland habitats in the Usambara Mountains of Tanzania, managers used the minimum distance from the corridor’s edge needed to find the most edge-sensitive bird species present (Newmark 1993). • To estimate forest corridor widths for North American songbirds, practitioners have used the distance into the forest at which nest predation and parasitism become negligible (Newmark 1993).
