Fort Rodd Hill and Fisgard Lighthouse National Historic Sites of Canada and Garry Oak Ecosystems
What are Garry oak ecosystems?
Garry oak ecosystems are ecosystems where Garry oak trees naturally occur. Climate, soil type and depth, slope, aspect, disturbance history, and other factors have created many different habitats within Garry oak ecosystems. These ecosystems consist of a mosaic of open and closed woodlands, moist flat meadows and grasslands, scattered stands of transitional forests and dry rocky outcrops with shallow soils.
These ecosystems are important not only for their great beauty, but also for their biological diversity. Together, Garry oak and associated ecosystems are home to more plant species than any other terrestrial ecosystem in coastal British Columbia , many of which occur no where else in Canada !
Where are the Garry oak ecosystems found?
Globally, Garry oak ecosystems have an extensive north-south range, from southwest British Columbia to southern California . In Canada , Garry oak ecosystems are found only in British Columbia - almost exclusively along the coast of southeast Vancouver Island , as well as in the nearby Gulf Islands and in two small stands in the Fraser River Valley . A significant amount of Canadian Garry oak ecosystems are found in Fort Rodd Hill and Fisgard Lighthouse National Historic Sites and Gulf Islands National Park Reserve.
