Inexpensive camera systems for detecting martens, fishers, and other animals: guidelines for use and standardization.

Inexpensive camera systems have been successfully used to detect the occurrence of martens, fishers, and other wildlife species. The use of cameras is becoming widespread, and we give suggestions for standardizing techniques so that comparisons of data can occur across the geographic range of the target species. Details are given on equipment needs, setting up the stations, checking and recording, summarizing data, and research needs.
