The following estimates were used to model impacts and represent the best information available at the time the impact assessment was completed and should not be used as policy direction. Not all Identified Wildlife are included in this table. Only those species that have a timber impact and whose number of occurrences are expected to increase were included. For some species the number of occurrences is known or was roughly estimated (i.e., Vancouver Island marmot, grizzly bear, white-headed woodpecker, sandhill crane and the four plant communities). For example, the total impact attributed to grizzly bears was based on an estimate of 3000 WHAs over the short term (10 years). The complete impact assessment is available through the MELP, Wildlife Branch, Identified Wildlife internet home page.
