The Illilouette Creek Basin in Yosemite National Park has experienced a large number of managed wildfires since 1972, when the managed wildfire program in this area began. The 1969 map captures vegetation cover following a period of at least 90 years with no wildfires above 5 ha in size within the watershed. This vegetation map was created in eCognition using aerial imagery provided by the Yosemite National Park archives, taken by Cartwright aerial surveys. Vegetation is divided into the following broad categories: conifer, shrubland, sparse vegetation, and dense meadow.
Vegetation Type Codes
0 - Exposed rock or open water
1 - Conifer (mainly Pinus contorta, Pinus jeffreyi, Abies magnifica, Abies concolor)
2 - Shrubland (mainly Ceanothus cordulatus)
3 - Sparsely Vegetated (but not exposed rock)
4 - Dense Meadow (most of this area is wetland, but not all could be verified as true wetland)
