Sensitive Ecosystems Inventory for East Vancouver Island and Gulf Islands began in 1993 and was redone using air photos taken in 2002. The study area is located in southwestern British Columbia on the eastern coastal lowland of Vancouver Island. It extends approximately 250 km from Campbell River in the north to Sooke in the south, and includes the adjacent Gulf Islands.

The study area is situated in the Nanaimo Lowland (NAL), Southern Gulf Islands (SGI) and Strait of Georgia (SOG) Ecosections and include the Coastal Douglas-fir (CDF) and the Coastal Western Hemlock (CWH) biogeoclimatic zones. The project files available are a project report, two spatial file and a digital map file. Results of this disturbance mapping show a disturbing trend. Over 8,800 ha (11%) of the area occupied by the nine SEI ecosystem types in the early 1990s had been disturbed by 2002. Over 1480 ha of disturbed area had originally been occupied by the seven sensitive ecosystems. Older forests had the highest rate of loss at 8.6% (915 ha) followed by riparian (4.6%), woodland (2.6%) and wetland (2.0%) ecosystems. The largest area of loss was 7,360 ha (16.4%) in the older second growth forest category. Losses due to fragmentation are currently being assessed and will add to these totals.
