The goal of the regional monitoring program is to evaluate the effectiveness of the Northwest Forest Plan in achieving its management objectives on federal lands in the planning area. Monitoring focuses on important regional scale questions about older forests, populations and habitat of northern spotted owls and marbled murrelets, watershed health, federal agency relationships with Indian tribes, and socioeconomic conditions in communities closely tied to federal lands.
