,The Forest Practice Watershed Mapper shows Anadromous Salmonid Protection status of planning watersheds as required of every timber operation, and provides data on the cumulative impact of timber harvest.,The Anadromous Salmonid Protection (ASP) Rules require that every timber operation contribute to salmonid habitat restoration.,The Forest Practice Watershed Mapper displays timber harvesting activities at the planning watershed level to provide information on past and present timber harvesting activities.,You can find your area of interest using a Calwater Planning Watershed number, a THP, WFMP, or NTMP number, or by Township, Range, and Section. You may also pan and zoom to the area of interest, interactively with the map.,Navigation and query tools allow users to focus on specific areas of the State, while a selection of base layers, including imagery and topographic maps, provide geographic context for the areas of interest.,

RdNBR is a remotely sensed index of the pre- to post-fire change in vegetation greenness, in this case the growing seasons in the year prior to and the year after the year in which the fire occurred. The mean composite scene selection method utilizes all valid pixels in all Landsat scenes over a specified date range to calculate the fire severity index. The CBI is a standardized field measure of vegetation burn severity (Key and Benson 2006), which here is predicted from a remotely sensed fire severity index using regression equations developed between CBI field plot data and the remote index, RBR (Parks et al 2019). The dataset featured provides an estimation of fire severity of past fires, with fire severity defined here as fire-induced change to vegetation. The dataset is limited to fires included in CAL FIRE’s Historic Wildland Fire Perimeters database and therefore is subject to the same limitations in terms of missing or erroneous data.,
