We live in a special place! Thetis Island lies within the Coastal Douglas-fir Biogeoclimatic  Zone (CDF) which is one of British Columbia’s smallest, most biodiverse and most at-risk zones. Over half of the area, which encompasses the Gulf Islands and southeast coast of Vancouver Island, has been permanently converted to buildings, roads, parking lots, farms and industrial areas, and less than ten percent of the original forest is left, much of it fragmented by logging roads. Every ecological community in the zone is considered imperilled by the BC Conservation Data Centre.

The CDF is also home to one the  highest number and densities of species in Canada, including rare and endangered species. So far, eighteen terrestrial species at risk have been documented on Thetis Island, including two plants, nine birds, two snails, two lichens, one amphibian and two mammals.  Working with our partner, the Islands Trust Conservancy, we carry out ongoing species at risk surveys in the Nature Reserves.
