Caption: The chart above shows vegetation types and timber size classes by acre of the Beaver 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 Beaver Creek as well as fire history. Haystack Fire in 1955 converted vegetation in much of the watershed to chaparral. Grasslands may be in part natural along upper ridges. See Info Links for more information. Classes include: 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,
