We examined the effects of cumulative winter climate on acorn yield and body weight of immature white-tailed deer (Odocoileus virginianus) the following autumn, and spring population density of deer on Land Between the Lakes (LBL), Tennessee. Body weights of male and female fawns and yearlings were positively correlated with acorn yield the previous autumn and inversely correlated with estimated spring population density of deer. Acorn yield was positively related, and spring population density of deer inversely related, with the cumulative number of days with >0.25 cm of precipitation during the previous 3 and 4 winters. Acorn yield and associated body weights were not related to total amount of precipitation, presumably because of the topography of the study area. Cumulative effects of winter climate should be considered in deer population models.
