Caption: The chart above shows vegetation types and timber size classes by acre of the Horse Creek watershed as derived from a 1994 Landsat image. The Landsat image was classified using the WHR method by the Humboldt State University Spatial Analysis Laboratory then modified for use in KRIS (see Info Links). The predominance of small trees (6-12 inches diameter) and small trees (<6 inches) and shrubs indicates fairly intensive timber management in Horse Creek. Grasslands may be in part natural along upper ridges. Classes are listed below:
Very Large Trees = 36" in diameter or greater,
Large Trees = 24-36" in diameter,
Medium Trees = 11-24" in diameter,
Small Trees = 6-11" in diameter,
Small Trees/Shrubs = Trees 1-6" in diameter and shrubs,
Shrubs,
Grass,
Rock/Soil,
Marsh/Meadow.
