Daily Activity Patterns

Unexploited populations of bobcats (Felis rufus) and coyotes (Canis latrans) were studied in the Elliott State Forest, Douglas and Coos counties, Oregon, from September 1981 to July 1982. A total of 633 radio locations of six bobcats and five coyotes were used to determine home ranges, activity, and habitat-use patterns. Twenty-five prey items were identified in bobcat and coyote scats. Diets of the two species were similar (overlap values were greater than 0.92 for all seasons). Mountain beaver (Aplodontia rufa) remains occurred in over 70% of the scats from both species. Home ranges for radio-collared animals averaged 14 km2 for male coyotes, 12 km2 for female coyotes, 11 km2 for one male bobcat, and 2 km2 for female bobcats. Bobcat and coyote home ranges overlapped in time as well as space. Radio-collared bobcats were detected on occasion within the same clear-cut sites concurrently with radio-collared coyotes, and daily activity patterns were nearly identical between the two predators. Bobcats and coyotes used open areas during nightly hunting activities and retired to forested areas during the day. Coyotes used grassy, more open clearings whereas bobcats favored brushy sites.

Species Specific

Abstract Timber resources are a vital part of the economy in the Pacific Northwest, yet reforestation efforts are often hampered by animal damage. Understanding the factors that influence seedling damage can assist managers in implementing appropriate techniques to reduce species-specific damage. I radio-collared and monitored mountain beavers (Aplodontia rufa) from preharvest to seedling planting to determine the impacts of forest management practices on demographics. In addition, I monitored Douglas-fir (Pseudotsuga menziesii) seedlings on 28 plots on two harvest units (Vesta and Schoolhouse) to determine the effects of chemical site preparation on mountain beaver foraging and subsequent seedling damage. Mountain beaver densities differed between silvicultural treatments (F3,39 = 3.58, P < 0.02), although reproductive success did not (χ2 = 0.14, df = 1, P = 0.70). Larger mountain beaver home ranges were documented in the mature timber compared with those following harvest. Home ranges were also larger in the chemical site preparation portion of the unit (mean = 3.37 ± 0.9 ha) than in the nontreated portion of the unit (mean = 0.82 ± 0.17 ha) on Vesta. Herbicide treatment did not promote seedling damage on either unit. Vegetation does not appear to be the only factor influencing mountain beaver movements and seedling damage. Availability of water is very important for mountain beavers and may also influence their foraging choice, as well as contributing to their increased movements in mature timber (reduced groundwater) versus clearcut areas. Understanding the effects of vegetation on population demographics and subsequent seedling damage may allow for initiating a nonlethal management method using alternative forage.
