Breeding Bird Surveys on the Southwest Coast of British Columbia: 2000-2007 Project Summary
Preston, Michael I.
This monitoring program began in 1999 when MacMillan-Bloedel Ltd., under the Coast Forest Strategy, adopted an adaptive management framework to address public and customer concerns over old-growth conservation and clearcut logging (Bunnell et al. 2003). The framework provides specific objectives that define goals for sustaining ecological values and allowing economic viability (Bunnell et al. 2003). One of those goals is to "sustain biodiversity" (native species richness and its associated values), which for practical application requires monitoring to assess effectiveness. Bunnell et al. (2003) and Kremsater et al. (2003) developed a set of indicators that encompass the complexity of biodiversity. The indicators include: 1) ecosystem representation; 2) habitat and structure representation; and 3) species' abundance, distribution, and reproductive success. Through the adaptive management framework it is intended that each of these indicators would be sustained, and that changes in one may reflect changes in another. For example, if significant declines in cavity nesting birds are observed over time, then it may be a reflection of a decrease in snag availability. Thus, prescribing minimum post-harvest snag densities may form part of the adaptive framework to mitigate against declines in cavity nesting species. Subsequent monitoring will assist in evaluating the effectiveness of such strategies.
