Effects of Short Duration Grazing on Deer Home Ranges

Twenty-three white-tailed deer (Odocoileus virginianus) were radio-tracked from February 1984 to February 1985 on adjacent south Texas areas subjected to short duration (SDG) and continuous (CG) cattle grazing. Deer that ranged between the 2 grazing treatments were termed border deer. There were no (P > 0.05) differences in home range size by grazing treatment or sex, but variability was high. Home ranges were similar for deer on the SDG vs. CG area in spite of a 62% greater stocking rate under short duration for 9 of 12 study months. During the last 3 months, stocking rate in the SDG area was 16% less than in CG.
