The Idaho Department of Fish and Game (IDF&G); Montana Fish, Wildlife, and Parks (MFWP); and the University of Montana (UM) are teaming up to test using camera traps to monitor white-tailed deer, mule deer, elk, and moose populations in Idaho and northwest Montana. This cooperative study builds on the work of UM graduate student Anna Moeller and Professor Paul Lukacs who developed three new, unbiased methods to estimate abundance using photos from trail cameras. In addition to abundance, the joint project will evaluate the use of remote camera data to monitor population composition and survival. IDF&G and MFWP are exploring this approach in response to the high cost, logistic challenges, and risk associated with aerial surveys, as well as the need to monitor populations in forested habitats where animals cannot be counted effectively from the air. This project is funded with state license revenue, Federal Aid in Wildlife Restoration funding, and contributions from the Rocky Mountain Elk Foundation and the Mule Deer Foundation.
