    National Interagency Canada Lynx Detection Survey in Minnesota, Wisconsin, and Michigan

    A variety of non-invasive techniques including hair snagging, snow-tracking, and remote cameras can be used to monitor mammalian carnivores. The National Interagency Canada Lynx Detection Survey (NLDS) was a survey designed to detect lynx with a hair-snagging protocol applied throughout the conterminous U.S. range of the lynx. Hare-snagging stations consisted of a scent lure, a carpet piece with nails to snag hair, and a pie tin to attract the cat’s attention. We applied the NLDS protocol in the Superior and Chippewa National Forests in Minnesota, the Chequamegon and Nicolet National Forests in Wisconsin, and the Ottawa National Forest in Michigan. Mammalian species detected included black bears (Ursus americanus), bobcats (Lynx rufus), coyotes (Canis latrans), ungulates, and other canids. The NLDS did not detect lynx in the Great Lakes Geographic Area (GLGA) despite their likely presence on some of the Minnesota NLDS grids. We also opportunistically set up hair snagging stations in areas in Minnesota where we knew lynx were present to further test the efficacy of hair-snagging stations. We had limited success using hair snares to selectively sample for lynx despite placing snares in areas regularly used by lynx. We suspect the detection probability for lynx hair-snagging surveys in the GLGA may be low and other survey techniques may prove more useful, particularly for localized selective sampling for lynx presence.
