||USFS Tree Size Classes: Grasshopper Cr CalWater 1994
||Caption: This bar chart shows vegetation and timber types of the Grasshopper Creek Calwater planning watershed. The U.S. Forest Service derived the information from a 1994 Landsat image. This analysis technique calculates averages of vegetation stands at a one-hectare scale. The high occurrence of Non-Forest and Saplings in this Calwater is indicative of very active timber harvest just prior to 1994. The 36% of the watershed in trees less than 12 inches in diameter suggests a watershed over thresholds for disturbance likely to exhibit cumulative watershed effects. See Info Links for more information. Vegetation classifications are:
Very Large Trees = >40" in diameter Large Trees = Trees 30-39.9" in diameter
Medium/Large Trees = 20-29.9" in diameter Small/Medium Trees = 12-19.9" diameter
Small Trees = 5-11.9" in diameter Saplings = Trees less than 5"
Non-Forest = No trees, shrubs, grass, bare soil
