Overabundance and associated impacts of deer on mainland forests of the United States have been topics of extensive investigation and management discussion. Conversely, deer populations on barrier islands have been less studied with few investigations of their impacts on maritime evergreen forest. We investigated how deer influenced understory vegetation and oak seedling survival following culling of deer. In 2007 twenty 10 m × 10 m paired exclosure and control plots were established within a 77.3 ha protected area on Bald Head Island, North Carolina. Vegetation was sampled in 2011. We determined deer did not affect understory vegetation and oak survival was low and not influenced by deer. Chronic over-browsing (i.e., ‘ghost of herbivory past’) was unlikely because deer were not abundant on Bald Head Island until the 1990s, oak seedlings were observed where light was abundant, and deer were observed using other cover types on the island. Continued monitoring of the forest understory and maintenance of deer at the current population level will help conserve maritime forest on Bald Head Island.
