Biography
Bret Wallingford is a deer biologist for the Pennsylvania Game Commission's Deer and Elk Management Section in the Bureau of Wildlife Management. His primary responsibilities include population analyses and research of white-tailed deer in PA. Bret attended Penn State University to earn a B.S. degree in Environmental Resource Management. He then attended North Carolina State University and conducted research on white-tailed deer on Remington Farms (now Chesapeake Farms) to earn his M.S. degree in Wildlife Biology. He began his career with the PGC in July 1990, working for 5 years on pheasant research. From 1995 to the present, Bret has worked on white-tailed deer management and research. He organizes the collection of sex-age-kill data for deer harvests, calculates the population estimates, and makes recommendations for antlerless allocations and deer hunting seasons. He also coordinates activities for the Section's research activities, which includes Game Commission technicians and graduate students. Bret is a certified wildlife biologist and a member of the Wildlife Society, and the Northeast Deer Technical Committee. He is married, has two children, and lives in Centre County, Pennsylvania. His time is spent gardening, coaching baseball, cutting firewood, and spending as much time as possible hunting, fishing, and exploring the fields and forests with his children. Bret has been an avid deer hunter for more than 35 years. . Bret's research interests include investig...
