The Northwest Forest Plan (the Plan) was developed in 1994 to resolve debates over old-growth forests and endangered species on federal forests in the range of the northern spotted owl. In 2005, federal agencies reviewed the first 10 years under the Plan to learn what worked and what did not, what changed, and what new information or surprises might influence these forests in the future. I highlight the monitoring results and new science from that review. Following are some of the key findings. Nearly all existing older forest habitat on federal land was protected from timber harvest. Older forest on federal land had a net increase of over 1 million acres in the first 10 years of the Plan. Despite protection of northern spotted owl habitat on federal land, spotted owl populations declined at a greater rate than expected in the northern half of their range, likely because of barred owl competition, climate, and the changing condition of historical habitat. Watershed condition improved slightly, because of reduced harvest in riparian areas, tree growth, and increased emphasis on restoration. Federal timber harvest in the Plan area averaged only 54 percent of Plan goals. In spite of mitigation measures, some local communities near federal lands had job losses and other adverse effects. State, federal, and tribal governments worked together on forest issues better than they ever had before. Increased collaboration with communities changed how the agencies get work done.

The fate of much of the world's terrestrial biodiversity depends upon our ability to improve the management of forest ecosystems that have already been substantially modified by humans. Monitoring is an essential ingredient in meeting this challenge, allowing us to measure the impact of different human activities on biodiversity and identify more responsible ways of managing the environment. Nevertheless many biodiversity monitoring programs are criticised as being little more than 'tick the box' compliance exercises that waste precious resources and erode the credibility of science in the eyes of decision makers and conservation investors. The purpose of this book is to examine the factors that make biodiversity monitoring programs fail or succeed. The first two sections lay out the context and importance of biodiversity monitoring, and shed light on some of the key challenges that have confounded many efforts to date. The third and main section presents an operational framework for developing monitoring programs that have the potential to make a meaningful contribution to forest management. Discussion covers the scoping, design and implementation stages of a forest biodiversity monitoring program, including defining the purpose, goals and objectives of monitoring, indicator selection, and the process of data collection, analysis and interpretation. Underpinning the book is the belief that biodiversity monitoring should be viewed not as a stand-alone exercise in surveillance but rather as an explicit mechanism for learning about how to improve opportunities for conservation. To be successful in this task, monitoring needs to be grounded in clear goals and objectives, effective in generating reliable assessments of changes in biodiversity and realistic in light of real-world financial, logistical and social constraints.
