Thin out the population or relocate some of coyotes to another reserve. That's my best guess.
As the manager of reserve the species of coyote can be protected from other population by protecting the ranchers. Fencing is technique by which we can protect the ranchers from being killed. There are some other damage control methods that can help solving this problem. This includes traps, guarding animals etc. The fencing technique is very economical and can be easily done to protect the other animals.
