Topic	Land Cover: USFS Veg Size for North Fork Alder Creek 1994

 

Caption:  This bar chart shows vegetation size classes in the North Fork Alder Creek Calwater Planning Watershed. This planning watershed had 42% of vegetation in medium-large and greater trees, 48% in small-medium and smaller trees and 10% in non-forest, which reflects riparian stand conditions that are insufficient for optimal large wood recruitment. 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.
