Rare and Sensitive Ecosystem Inventory Pilot Project - Weyerhaeuser, West Island Timberlands SEI Home Page

This project presents Sensitive Ecosystems Inventory (SEI) for Weyerhauser’s West Island Timberlands on TFL 44. It covers all of TFL 44 (over 277,000 ha) on Vancouver Island (47 mapsheets).

The project was funded by Weyerhauser as part of their CSA Certification.

A combination of SEI categories and at-risk ecological communities tracked by the BC Conservation Data Centre (Red and Blue list) were mapped using existing GIS layers such as Terrestrial Ecosystem Mapping (TEM) and forest cover.

This project was completed before the Standard for Mapping Ecosystems at Risk in British Columbia (RISC 2006) was released.

Field inspections were completed in 2003 on four 1:20 000 scale map sheets (Survey Intensity Level 4). Results were then used to revise the GIS model and to update specific map units. The remaining map sheets were then completed. Mapping is at 1:20,000 scale.
