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, parts of land put aside to facilitate the move of species and ecological procedures. despite the fact that, whereas thousands of hall tasks are below approach around the globe, there's little sensible details to steer their layout, place, and administration. Applying Nature's Design deals a accomplished review of present wisdom on corridors, their layout, and their implementation. Anthony B. Anderson and Clinton N. Jenkins study various conceptual and functional concerns linked to corridors and supply unique case stories from around the globe. Their paintings considers how one can deal with and govern corridors, find out how to construct help between a variety of curiosity teams for corridors, and the hindrances to implementation. as well as assessing quite a few environmental and ecological demanding situations, the authors are the 1st to contemplate the significance of socioeconomic and political matters in growing and retaining corridors.

Example text

Much of the early debate on corridors focused on either theoretical considerations or empirical observations showing (or failing to show) animal movement through habitat corridors (Noss 1987, Simberloff and Cox 1987, Hobbs 1992, Simberloff et al. 1992). With growing interest in the potential conservation values of corridors (probably sparked by this debate), scientists have carried out more research on corridor functions in recent years. Yet a review of thirty-two such studies revealed that only twelve allow meaningful inferences about corridor functions.

The sources where reproduction of such species takes place are likewise unknown, although ocean currents probably determine the route over which dispersal occurs. These issues raise special challenges for corridor design in marine environments. Since the source and the precise route of dispersal are in most cases unknown, patterns of ocean currents provide the best criterion for continued Corridor Design 35 defining linkages within marine systems, and between those systems and adjacent freshwater and terrestrial habitats.

The reverse of this critique may also be valid. Rather than making a case against corridors, the scarcity of scientific data in fact justifies more and better research (Hobbs 1992). In the meantime, the following factors merit consideration (Bennett 1999): • Currently there is no evidence that corridors have negative impacts on plant or animal populations, communities, or ecosystems (Beier and Noss 1998). 24 • • • applying nature’s design In the absence of complete information, it is safer to assume that the natural condition (a connected landscape) is preferable to an artificial condition (a fragmented landscape) (Saunders and Hobbs 1991a, Harris and Scheck 1991, Beier and Noss 1998).
