Animals are born to roam. So when they find themselves living on small patches of land surrounded by housing developments or cornfields, their movement is unnaturally confined. They may never find that other patch a mile down the road that is full of food, nesting grounds, even mates with differing genes (a very good thing for the health of a species.) What’s more, the plant seeds and pollen that naturally hitchhike with them are also stuck.
But, as conservationists discovered more than 40 years ago, if you connect these fragments with skinny strips of natural land, called “corridors,” plants and animals can more naturally spread. Now, results published online last week in the Proceedings of the National Academy of Sciences suggest the strategy’s benefits for biodiversity may even extend beyond the borders of these linked patches of land.
