ABSTRACT: White-tailed deer (Odocoileus virginianus) found at the mouth of the Mississippi River are of historical significance as they represent one major source used for restocking in Louisiana. Concerns over potential population declines led the Louisiana Department of Wildlife and Fisheries to initiate a study to gather demographic data on white-tailed deer on the 46,540 ha Pass-A-Loutre Wildlife Management Area. We captured and individually marked 57 deer on Pass-a-Loutre Wildlife Management Area (PALWMA). We monitored travel corridors using un-baited trail cameras and recorded all sightings of marked and unmarked individuals between 2007–2014. We collected photographic observations of 4,325 individual white-tailed, however the observation frequency of tagged individuals was low (n= 340; 7%). Based on the resighting data apparent annual survival for female and male white-tailed deer was 0.48 (SE = 0.07) and 0.78 (SE = 0.06), respectively and recapture probability was significantly higher for tagged males (0.81 (SE = 0.11)) than females (0.54 (SE = 0.08)). Overall, our estimates of female annual survival were low relative to estimates from other population studies from the southeastern United States. As coastal marsh habitats represent an important component of the statewide harvest in Louisiana, and as coastal habitats are slowly degrading in Louisiana, our results suggest that additional focus on white-tailed deer demography and harvest rates are likely necessary in coastal regions of the southeast.
