Wildlife corridors — strips of habitat connecting isolated patches — are essential for animal movement, genetic exchange and the ability to respond to climate change.
Habitat fragmentation forces animals to attempt road crossings in search of mates, food and territory — causing millions of road casualties annually. Animals trapped in isolated habitat patches face inbreeding depression, resource depletion and inability to disperse. The welfare impacts of corridor provision are indirect but profound: connected populations maintain social structures, allow young animals to disperse normally, and provide refugia during extreme weather. Animals experiencing landscape-scale connectivity can live more complete, behaviourally natural lives than those confined to ever-shrinking habitat islands.
