Abstract

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 2012 map captures vegetation after 40 years of managed wildfire, 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 from the National Agriculture Imagery Project. Vegetation is divided into the following broad categories: conifer, shrubland, sparse vegetation, dense meadow, and aspen.

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)
5 - Aspen
