Livestock guarding dogs

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.

Sam Linhart worked as a biologist in the predator control research section at the Denver Wildlife Research Center from 1964 to 1990. This collection contains materials from his studies related to predator control. Research records on electric fencing, leghold traps, the electronic guard, the 1080 toxic collar, livestock protection dogs, the M-44, and tranquilizer tabs for wild carnivore traps are included. This collection also contains images related to Linhart’s research.
