Techniques to Monitor Relative Abundance of Coyotes in East Tennessee

Scent stations, passive hair-snaggers and howl surveys were evaluated as possible survey methods for monitoring relative abundance of coyotes (Canis latrans) in Great Smoky Mountains National Park (GSMNP) prior to the reintroduction of red wolves (Canis rufus) from January 1990 to April 1991. Scent station nights (N = 198), passive hair-snaggers (N = 70), and howl surveys (N = 197) produced 1 (0.5%), 0 (0.0%), and 35 (17.8%) coyote responses, respectively. Scent stations and hair-snaggers proved ineffective for monitoring coyotes at current population levels. Howl surveys elicited...

Population Characteristics and Harvest Relationships of a Raccoon Population in East Tennessee

Controlled hunting (9-night season) and livetrapping of raccoons (Procyon lotor) on the Chuck Swan Wildlife Management Area was assessed in relation to total harvest, age and sex characteristics, reproductive parameters, and density estimates. From 1976 to 1978 hunting pressure and hunting success remained relatively constant while the total harvest decreased at an average of 23% annually from 175 (1975) to 80 (1978). Seventy-five, 69 and 69% of the 1976, 1977, and 1978 harvests were juveniles suggesting a greater vulnerability compared to adults; this occurrence also may be related to...
