Estimating Age and Antler Traits of Photographed Male White-tailed Deer

SEAFWA Journal Volume 2, March 2015
Wildlife Outstanding Technical Paper

Antler measurements are used to set harvest restrictions for male white-tailed deer (Odocoileus virginianus) and to evaluate response to management. Remotely-triggered trail cameras are popular research and management tools, but have not been used to estimate antler size or age. We developed methods to estimate antler measurements and age of male deer â?¥ 1 year old from photographs. We developed predictive equations for individual antler measurements using photographs of mounted deer heads, and evaluated five anatomical features for potential use as a known-sized scaling reference in...

Effects of Six Disking Regimens on Quail Foods in Fallowed Fields

The effect of disking fallowed agricultural fields was studied in the Piedmont and Coastal Plain of South Carolina. Six combinations of disking frequency and time-of-year and a control were tested. Although plant communities responded by returning to an earlier serai stage, well-established perennials prevented a complete return to Stage 1 succession. The effect of disking frequency proved more influential than that of time-of-year. Treatments were evaluated for their ability to produce food plants for northern bobwhite (Colinus virginianus). In the Piedmont, food values were found to have...
