Abstract: A trade-off between forage acquisition and predation avoidance often drives space use by prey herbivores. We tested the effects of manipulating forage production and residual forest cover on white-tailed deer (Odocoileus virginianus) space use and vulnerability to hunting on Anticosti Island. Our results demonstrated that deer space use and deer vulnerability to hunting could be modified by different structural components of the habitat. Forage productivity led to higher deer use of managed habitats, whereas decreased residual forest cover increased deer vulnerability to hunting. These results provide useful insights for wildlife managers who have to deal with conflicting goals such as maintaining hunter satisfaction with increased observations of deer while reducing deer densities which are undesirable in many economic and ecological aspects.
