Plant communities of Yellowstone National Park were classified by their development since the last major disturbance into units called cover types. Following a major disturbance such as fire, vegetation progresses through a series of plant communities (seral communities) toward the climax community. This process (succession) can be divided into the following classes called cover types: recently disturbed, early, mid , late and climax stages. To date, only the cover types of forested vegetation have been worked out. Therefore, this vector map shows the forested cover types of the Yellowstone National Park area. Aerial photographs of 1:15840 nominal scale from before the 1988 fires were interpreted with the help of ground truth transects throughout the park. A classified satellite image of October 2, 1988 identifying burn classes was used to modify the pre 1988 cover type map to reflect fires. As changes were noted on aerial photography of 1991 they were incorporated into the map. These were mostly areas that died after 1988 from surface burn that did not show on the satellite image.
