| Topic | VegType: Bluff Creek Watershed 1994 |
| Caption: The chart above shows vegetation types and timber size classes by acre of the Bluff 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 high small tree component (6-11" diameter) in Bluff Creek is in part a result of serpentine soils in the upper watershed that result in stunted vegetation. Many timber harvests in the 1960's and 1970's in Bluff Creek have not shown vigorous growth, possibly because of constraining soil types. This adds to the small tree component. See Info Links for more information. See below for classes: 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. | |
