Estimating White-tailed Deer Populations at the Wilds
Ryan BurkeApril 21, 2014
Biology Department
Deer population through
time 2008
What Changed? Habitat
Absence of predators
Hunting regulations
Protected areas
Significance Habitat
› Anderson 1997; › Fowler et. al., 2007
Agriculture› Rooney et al., 2010
Songbirds and small mammals› Ballard et. al., 2003; McShea & Rappole 1999› Bynam 2011
Disease› Bolzoni et. al., 2012; Duffy et. al., 2002
Objectives Determine if deer population is above
~ 25 individuals per square kilometer
Determine if areas at the Wilds have higher densities than other areas
Determine if there are more bucks than does or vice versa, or if both sexes are represented equally
