Over the years, the Mammal Damage Unit of the DWRC/NWRC conducted research on coyote predation on livestock; rodent damage to crops, rangeland, and buried cables; and damage to timber production and reforestation efforts caused by deer, bear, and rodents, particularly pocket gophers. The Unit also studied the use of pesticides as well as methods to identify and develop non-lethal or non-chemical alternative management methods for specific wildlife problems.
