Abstract
This report describes options for effectiveness monitoring of long-term status and trends to evaluate the success of the Northwest Forest Plan in maintaining and restoring marbled murrelet nesting habitat and populations on Federal lands. A two-phase approach is described that begins with developing reliable and repeatable processes for identifying nesting habitat and overcoming logistical and statistical problems before habitat and population trends can be accurately assessed. The second phase involves application of these processes to mapping and quantifying nesting habitat, and establishing populations in the Forest Plan area. The potential use of predictive models to evaluate the relation between terrestrial habitat use and conditions and population densities and trends is described along with a process for data analysis and reporting.
