Abstract:

Pen bioassays were conducted to evaluate the effectiveness of predator fecal odors as deer repellents. Aqueous extracts from predator feces were more effective than BGR (4.9% egg solids) and as effective as BGR-P (36% egg solids). In Test I, browsing reductions for the predator feces tested were: bobcat (Felis rufus)--51%; mountain lion (F. concolor)--27%; wolf (Canis lupus)--17%; and coyote (C. latrans)--8%. The efficacy of fecal extracts in Test I correlated with the concentration of predator feces in initial formulations (5, 10, and 20% by weight). In Test II, increasing the concentration of feces to 30% for bobcat and mountain lion did not increase their repellency. Fecal odors of predators significantly suppressed the feeding activities of black-tailed deer (Odocoileus hemionus columbianus); however, additional laboratory and fieldwork are needed before predator odors can be used operationally.
