What is the CDF

What is the Coastal Douglas-fir Biogeoclimatic Zone?

The Coastal Douglas-fir Biogeoclimatic Zone is a unique set of associated ecosystems that occurs on a narrow strip of south-east Vancouver Island, Gulf Islands, and the Sunshine Coast.  In this region, in the rainshadow of Vancouver Island and the Olympic Mountains, a Mediterranean-like climate exists, and allows for a rich flora and fauna to thrive.  It is important to understand that the Coastal Douglas-fir includes far more than just Douglas-fir forests.  In addition to those forests, the zone includes a wide variety of ecosystems, including Garry Oak ecosystems, wetlands, and shorelines. 

A more detailed description of the Coastal Douglas-fir Biogeoclimatic Zone can be found in the Ecosystems of British Columbia: Chapter 5 Coastal Douglas-fir Zone. (pdf)



What additional ecosystems are part of the CDFCP?

In addition to the Coastal Douglas-fir Biogeoclimatic Zone, the CDFCP has chosen to include the Coastal Western Hemlock, very dry maritime variant (CWHxm). The CWHxm has many rare ecosystem types, similar to the CDF. Additionally, some areas outside of the CDF and CWHxm have been included in the area of interest because of their integral position within the CDFCP planning area. These areas include components of watersheds and island that are related to CDF and CWHxm ecosystems.
