Topic	USFS VegTypes - Riparian Strips: Thompson Creek 1994

 

Caption:  This bar chart shows riparian tree size class of the Thompson Creek Calwater planning watershed. The Thompson Creek Calwater had less than 1% of the 90 meter riparian zones in large, 31% in small trees and 5.4% in non-forest as of 1994. The U.S. Forest Service derived the information from a 1994 Landsat image. This analysis technique is accurate at the stand rather than individual tree level. Scroll down for a key to classifications. Click on Picture to see an ArcView screen capture of the Thompson Creek Calwater planning watershed showing vegetation types. Vegetation is classified according to diameter at breast height (DBH): Giant = >50" DBH, V Large = 40-50" DBH, Large = 30-40" DBH, Medium/Large = 20-30" DBH, Small/Medium = 12-20" DBH, Small = 5-12" DBH, Non-Forest = No trees, shrubs, grass, bare soil.
