Land Cover: USFS Veg Size in Riparian for Rolling Brook 1994 |
|
Caption: This bar chart shows vegetation size classes in the riparian zone of the Rolling Brook Calwater Planning Watershed. The riparian zone encompasses a distance of 90 meters (300 feet) on either side of the stream channel. This planning watershed had 46% of the riparian in medium-large and greater trees, 51% in small-medium and smaller trees and 3% in non-forest. Rolling Brook has the highest number of larger trees of any of the Calwaters in the Middle Garcia sub-basin. 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. 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.
