Topic	USFS VegTypes - Calwater Area: Thompson Creek 1994

 

Caption:  This bar chart shows vegetation class size of the Thompson Creek Calwater planning watershed. The Thompson Creek Calwater had 27% of the basin in medium- large and greater trees, only 38% in small trees and 5% 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.
