Abstract: The objective of this study was to assess the long-term effects of browsing by White-tailed deer on plant communities on Anticosti Island. We compared the vegetation on Anticosti and in the archipelago of Mingan that was used as a control without deer. We described the vegetation in terms of height, cover, and species composition in 4 different habitats and in exclosures protected from browsing for 5 years on Anticosti. The total number of species present in each habitat type did not differ between Anticosti and Mingan. However, we found differences between the two sites in terms of species composition. The age structure of fir stands has been particularily modified on Anticosti due to the absence of fir regeneration. However, many species associated to fir stands recovered when protected from deer browsing in exclosures. Browsing by white-tailed deer severely influenced the composition and structure of the vegetation on Anticosti and modified the natural succession.
