Land & Resource Management Plan (L&RMP) Land Suitability Class This is a derived layer of forestland capability, suitability and availability for timber production. Water is assigned census or non-census water using the water bodies layer. Land is assigned to forest or non-forest using existing vegetation. Forestland both capable (productive) and other (non-productive) forestland, as well as non-forest are determined by CALVEG types (TABLE 38). Each CALVEG type is assigned a forest productivity code (TABLE 43). Suitability information is derived from productive forest CALVEG types that are available, minus the unsuitable forestlands (UNSU). Availability (TABLE 11) is derived by determining all forestland from...

The Interagency Vegetation Mapping Project (IVMP) provides maps of existing vegetation, canopy cover, size, and cover type for the entire range of the Northern Spotted Owl using satellite imagery from the Landsat Thematic Mapper (TM). This area is commonly called the FEMAT area, in reference to the area's analysis by the Forest Ecosystem Management Assessment Team. A regression modeling approach was used to predict vegetation characteristics from this Landsat data. This process involved the use of numerous sources of ancillary data, the most crucial being USFS, BLM, and Forest Inventory and Analysis (FIA) plot field data and plot photo interpreted information. This data served as training data in the regression...

The risk mapping effort was initiated in 1995 with the formation of a group of specialists from several disciplines including representatives from state and other federal agencies to map and identify risk to insect caused tree mortality. An area is defined to be at risk if 25% or more tree mortality (beyond the normal level of approximately 0.6% annually) is expected over the next 15 years. This effort developed a statewide insect mortality risk layer based upon rules and statistics developed for the National forests and expanded to cover all state and private forest land. Rule structures were based primarily upon stand density index and also included, precipitation, percent canopy cover of host species, and host...
