An Analysis of Scent Station Response in Louisiana

An annual scent station survey was conducted in Louisiana from 1978 through 1982 to determine relative abundance of bobcats (Felis rufus) and relate indices to geographical regions and habitat types. A total of 29 lines each with 50 stations per line was proportionally divided into 5 regions. The use of fatty acid scent resulted in an average visitation rate of 4.6% for bobcats, 9.7% for coyotes (Canis latrans), 7.3% for fox (Vulpes vulpes and Urocyon cinereoargenteus), 7.2% for raccoon (Procyon lotor), 11:8% for opossum (Didelphis virginiana) and 7.1% for skunk (Mephitis mephitis). Significant differences were detected among years, regions and habitats for bobcat (P < 0.01). Regional visitation rates varied for coyotes with current harvest data supporting survey results (P < 0.01). Significant differences occurred among years and regions for fox (P < 0.01). For raccoon, significant differences were detected among regions, among years within 4 regions, and among habitat types in 4 regions (P < 0.01). Visitation rates for opossum varied among years, regions, years within 4 regions, and by habitat within 4 regions. Significant differences were detected for skunks between years, regions, years within 2 regions, and between habitats within 3 regions.
