||USFS Riparian Tree Size Classes: Stewarts Creek CalWater 1994
||Caption: This bar chart shows vegetation and timber types of the riparian zone of the Stewarts 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 Stewarts Creek riparian zone had a low amount of Non-Forest (1%). The largest vegetation type component is Medium-Large Trees (20-29.9") which were 51% of the riparian area. Small-Medium Trees (12-19.9" diameter) made up 13% of the riparian but trees less than 12" made up 45% of the riparian which would make this reach subject to warming. 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
