A wildlife corridor, habitat corridor, or green corridor[1] is an area of habitat connecting wildlife populations separated by human activities or structures (such as development, roads, or land clearings). It allows for the movement of individuals between populations, that may help prevent negative effects of inbreeding and reduced genetic diversity (via genetic drift) that can occur within isolated populations. Corridors also help facilitate the re-establishment of populations that have been reduced or eliminated due to random events (such as fires or disease) and may moderate some of the worst effects of habitat fragmentation,[2] through urbanization that splits up habitat areas, causing animals to lose both their natural habitat and the ability to move between regions to access resources. Habitat fragmentation due to human development is an ever-increasing threat to biodiversity,[3] and habitat corridors serve to reduce its harmful effects.[4]
