The Audit of Selected Polygons of the Sensitive Ecosystems Inventory of East Vancouver Island and the Gulf Islands, 1999-2001 (the audit) was designed to document disturbances due to land development to sites identified in the original SEI. Areas showing a high degree of urban and rural growth were selected for review, as the focus of the study was on changes to the urban/rural landscape rather than areas whose primary land use is forestry.
This report correlated these disturbances to the SEI Ecosystems within broad land use categories.
Between 1993 and 1997, the Ministry of Environment, Lands and Parks and Environment Canada conducted the Sensitive Ecosystems Inventory of East Vancouver Island and Gulf
Islands (SEI). The SEI identified and mapped the larger remaining areas of rare and/or sensitive ecosystems using aerial photographs primarily from1991-1993. Seven Sensitive Ecosystems and two Other Important Ecosystems were identified and mapped as polygons. The SEI showed that only 7.9% of the study area contained Sensitive Ecosystems. The Other Important Ecosystems accounted for another 11.6% of the land
base. For this report, the nine ecosystem types are collectively referred to as SEI Ecosystems.
