Terrestrial Ecosystem Mapping was completed for 143 hectares on the Saanich Peninsula on Vancouver Island, in the CDFmm biogeoclimatic subzone. The study area is home to rare and sensitive sand dune and estuarine ecosystems. Sixteen natural ecosystems and four anthropogenic units are mapped. Eight of the natural ecosystems are red-or blue-listed in BC. Mapping follows 1998 TEM standards in most aspects, with an Ecosystem Survey Intensity Level 3 and a Terrain Survey Intensity Level C.

Terrestrial Ecosystem Mapping of TIXEN/Cordova Spit was completed for 143 hectares on the eastern coast of the Saanich Peninsula on Vancouver Island, in the Coastal Douglas-fir Moist Maritime (CDFmm) biogeoclimatic subzone. The study area is home to rare and sensitive sand dune and estuarine ecosystems. The area falls under the jurisdiction of several groups. TEM was completed to inform a multi-jurisdictional conservation plan. The TIXEN landscape has evolved since the last glaciations. Glacial deposition, sea level change, climate change, long shore drift, erosion and deposition of sediments by wind and water, and human activities have contributed to the current ecological state of the area. Twenty one map units are mapped including sixteen natural ecosystems and four anthropogenic units. Eight of the natural ecosystems are red-or blue-listed in BC. Although approximately eighty-six percent of the study area is natural ecosystems, various disturbances are common in the study area. The TEM identifies sixty-one polygons. Twenty-one were field inspected for an ecosystem survey intensity level (ESIL) of 3 and a terrain survey intensity level (TSIL) of C. Anthropogenic influences that continue to threaten the natural ecosystems include introduced plant invasion, altered drainage, development, recreational activities and shore line stabilization. An overarching multi-jurisdictional management plan is required to manage the varied interests on the land. The Coast Information Team responsible for ecosystem based management (EBM) on the north and central coast of BC produced a framework that can provide a starting point for the creation (or enhancement) of a management plan in TIXEN.
