Ecologically, Coyotes might just be a key savior in the recovery of our loss of biodiversity (the number of species of plants, animals, and other life forms in a given area). It’s like the story on how the return of the wolves completely transformed Yellowstone. Our natural areas are besieged with plants from other parts of the world (non-native species). You would think adding plants from other parts of the world increases diversity. The opposite is true.
