| Distribution of Canada lynx in Yellowstone National Park | |
| 2006 Northwest Science (80): 199-206 | |
Little is known about Canada lynx in Yellowstone National Park, except that the species was present at the park's inception in1872 and may have persisted to the present. The lack of basic information in the park and this species' listing as threatened in the contiguous U.S. by the Fish and Wildlife Service prompted our 2001-2004 survey of lynx presence and distribution. We traversed track detection transects during winter and used hair snares in summer to detect lynx in select habitats. Using DNA extracted from hair or fecal samples, we confirmed the presence of a female (unknown age), an adult female with a male kitten, and an adult male, each detected in a different year in the eastern portion of the park. Eight other unconfirmed lynx snow trails were also identified, including three from the central portion. Cumulatively, our detections represented at least three individuals, including two kittens born in different years. A male we identified in 2004 was detected 76 km south the following year in the Bridger-Teton National Forest, demonstrating that significant movement of lynx occurs within the Yellowstone Ecosystem. Reproduction that we and others documented, in addition to immigrants from peripheral populations, may contribute to lynx presence in the ecosystem. |
