Land Cover: USFS Veg Size in Riparian for John Smith Creek 1994 |
|
Caption: This bar chart shows riparian vegetation size classes for the John Smith Creek Calwater Planning Watershed, derived from a 1994 Landsat image by the U.S. Forest Service. Riparian vegetation is defined here as 90 meters (292.5 feet) on either side of the channel. This planning watershed had 35% of the riparian in medium-large and greater trees, 62% in small-medium and smaller trees and 3% in non-forest. The vegetation classification is accurate at a one hectare scale and is suitable for stand classification. Click on Map to see riparian vegetation size classes in the Calwater Planning Watershed. Vegetation is classified according to diameter at breast height (DBH):
Giant = >50" DBH, V 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.
