This report describes options for effectiveness monitoring of long-term status and trends of the northern spotted owl to evaluate the success of the Northwest Forest Plan in arresting downward population trends, and in maintaining and restoring the habitat conditions necessary to support viable owl populations on Federal lands. It describes options to address monitoring questions, profiles population and habitat status, and points out areas of progress and concern. How population and habitat data from demographic studies would be integrated in the development of predictive models is described. A process to report status and trend results is presented that could provide a reference document for decisionmakers during periodic land use plan reviews.
