Rate of Change in Population of White Tailed Deer

APES-FVX1FF

On a small island in Maine, the population of white tailed deer, Odocoileus virginanus, was estimated to be 320 in 2009. During that year, 100 were reported by hunters at tagging stations and researchers estimate 25 births on the island. The proximity to the mainland has allowed for 11 immigrants during an early spring bloom.
