A wildlife corridor or green corridor[1] is an area of habitat connecting wildlife populations separated by human activities (such as roads, development, or logging). This allows an exchange of individuals between populations, lowering inbreeding within populations, so increasing effective population size, and facilitating re-establishment of populations that have been decimated or eliminated due to random events. This may potentially moderate some of the worst effects of habitat fragmentation[2].
Wildlife corridors are susceptible to edge effects; habitat quality along the edge of a habitat fragment is often much lower than in areas further from the habitat edge. Wildlife corridors are important for large species requiring significant sized ranges; however, they are also vital as connection corridors for smaller animals and plants as well as ecological connectors to provide a rescue effect.
