||USFS Riparian Tree Size Classes: Robinson Creek CalWater 1994
||Caption: This bar chart shows vegetation and timber types of the riparian zone of the Robinson 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. Scroll down for a key to classifications. The Robinson Creek riparian zone was very similar to that of Doty Creek. It had no Non-Forest component but trees under 12" in diameter comprised 25% of the riparian area. The largest vegetation type component is Medium-Large Trees (20-29.9"), which was 47%, and Small-Medium Trees (12-19.9" diameter) made up 26% of the riparian. 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" in diameter
Small Trees = 5-11.9" in diameter Saplings = Trees less than 5"
Non-Forest = No trees, shrubs, grass, bare soil
