Reproductive Ecology of White-tailed Deer on the Welder Wildlife Foundation, Texas

Long-term reproductive, physiological, and population data are not commonly available for deer herds. In Texas, there is little data on populations that are not commercially hunted. Data were recorded from 943 white-tailed does (Odocoileus virginianus) collected from 1961-1992 on the Welder Wildlife Foundation. Age class, eviscerated carcass weight, kidney fat index, density, and rainfall were correlated with reproductive performance including birth dates, pregnancy rates, and counts of corpora lutea and embryos. Deer densities averaged 33/km2. Mean conception date was 22 November and 75%...

Accuracy and Precision of Line Transect Procedures for White-tailed Deer

White-tailed deer (Odocoileus virginianus) densities and sex ratios were determined during 2 seasons for a semiconfined population. Two drive counts were used to estimate deer densities when an entire area was traversed, once in early winter and once in summer. In addition to the 2 drive counts, 5 random transects, totaling 4.5 km, were walked 6 times (3 times in fall and 3 in summer). Eighteen different density estimators were calculated using the line transect data. Compared to the density estimates derived from drive counts, the Hayne Constant Radius estimator gave the most accurate...
