Understanding Deer, Bear, and Forest Trends in the North Georgia Mountains: The Value of Long-term Data

Wildlife Outstanding Technical Paper
SEAFWA Journal Volume 5, March 2018

Most state wildlife agencies collect harvest data to inform management decisions. However, these data are typically considered across relatively short time periods and are rarely revisited. We present a case study using historical records to investigate potential agents (i.e., harvest, predation, and forest change) influencing the declining white-tailed deer (Odocoileus virginianus) population in the north Georgia mountains. We used long-term black bear (Ursus americanus) and deer harvest data, and indices of forest stand conditions from 1979-2015 on eight Wildlife Management Areas (WMAs)...

Survival and Cause-Specific Mortality of White-tailed Deer in Southeastern Kentucky

SEAFWA Journal Volume 5, March 2018

White-tailed deer (Odocoileus virginanus) are the most sought after game species in Kentucky. Deer numbers in southeast Kentucky are relatively low compared to other areas of the state, even after a decade of restrictive doe harvest and prior population supplementation. We estimated survival and assessed cause-specific mortality of a representative deer population in this low-density area within or near the Redbird District of the Daniel Boone National Forest in southeastern Kentucky from January 2014-January 2017. Estimated annual survival for does averaged 0.89 and was relatively high...

Population Growth and Mortality Sources of the Black Bear Population in Northern Georgia

SEAFWA Journal Volume 4, March 2017

An understanding of black bear (Ursus americanus) population trends and cause-specific mortality is needed to direct management decisions in northern Georgia given an increasing human population. Therefore, we evaluated black bear population trends and mortality sources across 26 counties and 18 Wildlife Management Areas in northern Georgia from 1979-2014. We collected harvest data from 6,433 individuals during the study period. Using age-at-harvest data, population reconstruction illustrated an increasing trend in the bear population for both males (λ = 1.113) and females (λ = 1.108)....
