A
wildlife corridor,
habitat corridor, or
green corridor is an area of
habitat connecting
wildlife populations separated by human activities or structures (such as roads, development, or logging). This allows an exchange of individuals between populations, which may help prevent the negative effects of
inbreeding and reduced genetic diversity (via
genetic drift) that often occur within isolated populations. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to
random events (such as fires or disease).
