Topic	Land Cover: USFS Veg Size for Lower Brush Creek 1994

 

Caption:  This bar chart shows vegetation size classes in the Lower Brush Creek Calwater Planning Watershed. This planning watershed had 23% of vegetation in medium-large and greater trees, 31% in small-medium and smaller trees and 46% in non-forest. Much of the non-forest condition in this watershed results from natural grasslands, agricultural areas and pasture along the coast, although early seral conditions may also be somewhat owing to recent timber harvest. The information was derived from a 1994 Landsat image by the U.S. Forest Service. This analysis technique calculates averages of vegetation stands at a one-hectare scale, and therefore is accurate at the stand rather than individual tree level. Click on InfoLinks for more information. See the Map tab for spatial data. 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.
