Proceedings of the Vertebrate Pest Conference

Information regarding the demographics and physical condition of mountain lions (Felis concolor) killed during damage control efforts in Nevada was gathered and compared to sport harvested mountain lions. The average age of depredating male lions was 4.92 years of age compared to 4.95 years for sport harvested males. Depredating female lions were older than sport harvested females averaging 5.09 years compared to 4.44 years. Older age class mountain lions of both sexes were more likely to commit depredations than expected. Male lions were involved in depredations 45% more often than females. Domestic sheep comprise more than 90% of depredation events in Nevada.
