This file geodatabase feature class contains attribute information from three mid-level existing vegetation maps (1:100,000) prepared for the Caribou-Targhee National Forest to provide up-to-date and more complete information about vegetative communities, structure, and patterns across the forest. Over 3.1 million acres (including private and state land inholdings) were mapped through a partnership between the Remote Sensing Applications Center (RSAC), the Caribou-Targhee National Forest (CTNF), and the Intermountain Regional Office VCMQ team. The VCMQ team prepared the regional classification system, identified the desired map units (map classes) and provided general project management. RSAC provided expert vegetation mapping support and implemented a field sampling strategy. Integrated Resource Inventory field crews visited the sites and recorded ground-level information. Forest Inventory and Analysis (FIA) personnel supplied supplemental photo-interpreted sites for areas that were difficult for field crews to access. Modeling units (mapping segments) were characterized by vegetation type, tree and shrub canopy cover, and tree size class using the 2011 field data, Landsat and aerial imagery acquired through 2011, and multiple ancillary geospatial data sets. Map features (the final map polygons) were designed to meet a minimum size of 5 acres with the exception of riparian vegetation map units which had a minimum size of 2 acres. All map products were designed according to the Forest Service mid-level vegetation mapping standards in order to be stored in the Forest GIS and National databases. Map units from the Bridger-Teton National Forest Mid-Level Existing Vegetation Maps that occurred along the shared border of the two forests are included in these maps. This was done in an attempt to portray continuity between forest maps.
