We are monitoring (a) potential associations between forest road conditions and downstream sediment conditions, (b) the locations of road-stream sediment delivery, with detailed estimates of the quantity of sediment delivered to streams from each source, and (c) long-term changes in aquatic conditions associated with terrestrial restoration treatments in watersheds. We are using two tools: 1) Geomorphic Road Analysis and Inventory Program (GRAIP) and 2) PACFISH-INFISH Biological Opinion (PIBO) monitoring tools. GRAIP is a road inventory procedure that records drainage locations, landslides, and gullies and provides erosion rates based on installed sediment traps. PIBO tools measure in-stream sediment.
