Evaluation of Population Estimates of White-tailed Deer from Camera Survey

SEAFWA Journal Volume 1, March 2014

Use of trail cameras to make population estimates of white-tailed deer (Odocoileus virginianus) has increased since an estimator was developed by Jacobson et al. (1997). We evaluated the accuracy of the camera estimator in six 81-ha enclosures with varying densities of deer replicated on two study areas. Baited camera surveys were conducted for 14 days in autumn and winter. We also tested the finding from previous studies that the probability of sighting bucks and does in photographs was equal. Finally, we conducted an open range test by comparing a camera survey to a helicopter survey....

Does Supplemental Feeding of Deer Degrade Vegetation? A Literature Review

Artificially feeding deer is controversial, particularly in North America. Our objective was to determine if published literature supports the hypothesis that supplemental feeding of deer leads to overuse of palatable plants and vegetation degradation. We found 16 papers regarding the feeding of deer through a search of the literature since 1989. Recent studies have not provided conclusive evidence that supplemental feeding of deer enables herbivores to concentrate feeding on the most palatable native foods in their environment or that it results in degradation of vegetation within the...
