Topic	Land Cover: USFS Veg Size for Ray Gulch 1994

 

Caption:  This bar chart shows vegetation size classes in the Ray Gulch Calwater Planning Watershed, derived from a 1994 Landsat image by the U.S. Forest Service. This planning watershed had 36% of vegetation in medium-large and greater trees, 52% in small-medium and smaller trees and 12% in non-forest. Small diameter trees in this Calwater are due in part to recent timber harvests, but some of the Non-Forest component is due to grasslands along Navarro Ridge to the west. The vegetation classification is accurate at a one hectare scale and is suitable for stand classification. Click on Map to see vegetation size classes in the Calwater Planning Watershed. Vegetation is classified according to diameter at breast height (DBH): Very Large = 40-50" DBH, Large = 30-39.9" DBH, Medium/Large = 20-29.9" DBH, Small/Medium = 12-19.9" DBH, Small = 5-11.9" DBH, Saplings = 1-4.9" DBH, Non-Forest = No trees, shrubs, grass, bare soil.
