Abstract
This experiment produced data on gains and losses during a 4-year period. A high rate of increase (1.9 fawns per adult doe) was found during a 2-year period in a deer population held in an enclosure when natural food was abundant. Following this 2-year period, the area was severely overbrowsed and deer died during the winter from malnutrition. A low rate of increase (.43 fawns per adult doe) was found during a 2-year period after the enclosure was overbrowsed and when just enough natural food was present to sustain the population. The study did not show any specific reason for the low rate of reproduction other than malnutrition resulting from a depleted food supply. The study indicated that mortality among fawns between birth and their first winter was negligible. All data relative to the deer population for all 4 years are given in 3 tables.
