Description: This feature class contains attribute information from four mid-level existing vegetation maps (1:100,000) prepared for the Chugach National Forest, Kenai Wildlife Refuge, and Alaska Fish and Game to provide up-to-date and more complete information about vegetative communities, structure, and patterns across the Forest. Over 5.7 million acres (including other federal, state, native, and private land inholdings) were mapped through a partnership between the Geospatial Technology and Applications Center (GTAC), Chugach National Forest, Alaska Regional Office, State of Alaska, Kenai National Wildlife Refuge, Kenai Burough, and National Park Service. The Chugach National Forest and their partners prepared the regional classification system, identified the desired map units (map classes) and provided general project management. GTAC provided project support and expertise in vegetation mapping. A combination of ground and helicopter reference data was used to inform the classification models that output the final maps. Federal and State field personnel collected plot data on the ground, while Ducks Unlimited and GTAC personnel collected the helicopter data. Classification models were used to characterize modeling units (mapping polygons) with the following vegetation attributes: 1) dominance type; 2) tree canopy cover; 3) tree size; and 4) tall shrub canopy cover. The minimum map feature depicted on the map is 0.25 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. This map product was generated using imagery primarily acquired in 2016 and 2017. The field data used as reference information for this mapping project was collected in the summer of 2017. Therefore, the final map can be considered indicative of the existing vegetation conditions found on the Kenai Peninsula in 2017.
