Large Wood in Streams

The importance of large wood in aquatic and riparian ecosystems is well recognized. To improve our understanding of wood dynamics in streams, we constructed wood budgets to identify the primary controls on recruitment, transport, and storage of wood along 100 km of northern California streams. The large data set shows that reach scale variability in wood storage and recruitment is the rule, driven by variation in rates of bank erosion, forest mortality, and mass wasting. The recruitment processes are controlled by changes in watershed structure including the location of canyons, floodplains, and tributary confluences, types of geology and topography, and forest types and management history. The findings were used to improve protection of riparian wood sources and inform spatially explicit riparian management.
