The Gulf Islands are home to one of the last remaining pockets of Garry oak ecosystems. Only about five percent of Garry oak ecosystems remain in their natural state, landing 91 of the approximately 350 species it supports on the province's list of species at risk. The unique Mediterranean characteristics of the islands' climate supports the Garry oak ecosystem. Garry oak ecosystems are home to more plant species, such as the camas, than any other terrestrial ecosystem in coastal B.C. and are one of Canada's most at-risk natural habitats.
