ATBI Mammal Investigation

Linzey, Donald

The researcher has been trapping to attempt detection of a least weasel (Mustela nivalis) in the park without success. The only area of promise is around Roaring Fork, as this species has been found outside the park in this watershed, but 500 trap nights in 2009, 3206 trap nights in 2010, and 200 trap nights in 2012 caught none. A previously unknown population of hispid cotton rat (Sigmodon hispidus) was discovered along Copeland Creek. Between one and three infrared remote heat-sensing cameras were in operation during most of the year in an attempt to capture a photograph of a cougar (Puma concolor) and rubbing pads were set out in an attempt to collect cougar hair samples. Photographs were obtained of coyotes, bears, deer, turkeys, opossums, and shrews but not of any cougar. Hair snares were set out over several years and samples collected were of bobcat, coyote, red fox, black bear. Trails were searched for scat, but only bobcat and coyote were detected. Over 20 reported cougar sightings were investigated, including damage to three horses in Cades Cove in 2010, but no positive evidence has been found. Eight scat samples were collected in 2012 for DNA analysis as possibly from mountain lion. Six reports were followed up in 2014. Researcher has trapped for small mammals at Tremont, Ramsey Cascades, Twentymile and Andrews Bald and in 2008 began to examine coyote stomach contents and scat to determine eating habits. PI is working on a paper with co-PI Alex Kumar on bait preference for small mammals in the park.
