Topic	Land Cover: USFS Veg Size for Point Arena Creek 1994

 

Caption:  This bar chart shows vegetation size classes in the Point Arena Creek Calwater Planning Watershed. This planning watershed had 47% of vegetation in medium-large and greater trees, 27% in small-medium and smaller trees and 26% in non-forest. Non-forest is related to grassy headlands along the 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. Click on the Map tab to see 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.
