Illilouette Creek Basin Vegetation Maps

These vegetation maps were created in order to assess the changes in land cover caused by 40 years of managed wildfire within the Illilouette Creek Basin of Yosemite National Park. Between 1980 and 1973, only 8ha are known to have burned within the watershed. Since 1973, over half of the watershed has burned at least once (including 75% of the vegetated area). Vegetation was divided into the following categories using eCognition software and the best available aerial imagery: conifer forest, shrubland, sparse vegetation, dense meadow, and aspen.
