Imagine a vast agricultural field, endless rows of soy or corn running for acres in every direction. Now imagine that this field grows where a mighty forest once stood. The forest, long since chopped down by human hands and machines, now exists in just a handful of pockets, a few spots here and there where the original trees — and their inhabitants — still live.
It shouldn’t be a hard image to visualize. We’ve all seen it: the lonely patches of forest, grassland or other natural systems squeezed between farmland, buildings or highways.
