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

 

Caption:  This bar chart shows vegetation size classes in the riparian zone of the Lower Brush Creek Calwater Planning Watershed. The riparian zone encompasses a distance of 90 meters (292.5 feet) on either side of the stream channel. This planning watershed had 24% of the riparian in medium-large and greater trees, 41% in small-medium and smaller trees and 35% in non-forest. The non-forest is largely owing to grassy headlands and farm country adjacent to the Mendocino Coast. 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, Non-Forest = No trees, shrubs, grass, bare soil.
