Topic	USFS VegTypes: May Creek Calwater 1994

 

Caption:  This bar chart shows vegetation class size of the May Creek Calwater planning watershed (upper Prairie Creek). The May Creek Calwater had 84% of the basin in medium large and greater size classes, only 12% in smaller size classes, and 3% 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 May 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.
