By Anthony Anderson, Clinton N. Jenkins

The fragmenting of habitats is endangering animal populations and degrading or destroying many plant populations during the global. to deal with this challenge, conservationists have more and more became to organic corridors, components of land put aside to facilitate the move of species and ecological methods. besides the fact that, whereas thousands of hall tasks are below manner all over the world, there's little sensible details to steer their layout, place, and administration. Applying Nature's Design deals a entire assessment of present wisdom on corridors, their layout, and their implementation. Anthony B. Anderson and Clinton N. Jenkins learn numerous conceptual and useful matters linked to corridors and supply precise case reviews from worldwide. Their paintings considers the right way to deal with and govern corridors, tips to construct help between quite a few curiosity teams for corridors, and the stumbling blocks to implementation. as well as assessing quite a few environmental and ecological demanding situations, the authors are the 1st to think about the significance of socioeconomic and political concerns in growing and protecting corridors.

These would allow all species in an ecosystem to shift their distributions to new, suitable locations. Source: Hobbs and Hopkins 1991. connectivity, and habitat quality (Thorne 1993). Width determines how much of the corridor interior is exposed to disturbances or edge effects, whether natural or human-induced, from the surrounding matrix. Connectivity refers to the degree to which gaps interrupt corridor habitat. Quality depends on both width and connectivity and reflects how closely the corridor approximates pristine habitat.

The diverse values provided by landscape connectivity for conservation of biological diversity, land uses, and aesthetics 22 applying nature’s design are indisputable. Where scientists have disagreed is whether corridors—and in particular relatively small-scale, linear corridors—are the best or even a sound strategy for mitigating the effects of habitat fragmentation (Harrison and Bruna 1999). The debate has focused on the capacity of linear corridors to facilitate animal movement in fragmented landscapes, and the potential role of such corridors in conserving animal populations and their habitat.

While approximately 25 percent of the country’s territory currently is under protection, the government has committed to preserving a minimum of 60 percent under forest cover in perpetuity. The establishment and maintenance of corridors linking existing protected areas would play a key role in achieving this ambitious goal. continued Corridor Design 45 WWF developed a preliminary plan for a national system of corridors in Bhutan. The process of selecting land for corridor designation involved a scoring mechanism in which land was rated for suitability according to specific criteria, including: • • • • • • • abundance of target wildlife or their prey (focal species), width of the narrowest constriction (corridor width), movement of key wildlife species (connectivity), condition of habitat canopy and undergrowth (habitat quality), levels of human disturbance (habitat quality), occurrence of forest fires (habitat quality), and slope of terrain (landscape features).
