This project, a part of the Columbia Habitat Monitoring Program (CHaMP), looked at wood loads, and the hydrogeomorphic and ecological factors that correspond to them in seven CHaMP-monitored watersheds. Historically, models of wood have been site specific, providing detailed inference into the processes that shape wood recruitment, transport, and storage at a single reach or a few reaches. In contrast, watershed managers, including habitat restoration biologists and stream restoration practitioners, often need to know what processes or pattern correspond to a given habitat attribute at broad scales. In the Pacific Northwest of the continental United States, numerous sub-basins are monitored for trends in their condition over time. Because wood may be the primary element shaping aquatic habitats in small streams, reaches or entire watersheds, areas that lack wood should be identified for restoration. More importantly, areas that are inherently wood-limited by the processes that grow trees, recruit them to the channel, and move them throughout a stream network should be identified. By identifying these patterns, basin-specific hypotheses (and models) can be constructed
