A wildlife corridor or green corridor1 is a strip 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 fragmentation2.
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 may be controversial if they interfere with human activities. However, they are potentially important for large species requiring large ranges.
