USFS Riparian VegTypes: Redwood Creek Estuary 1994 |
|
Caption: This bar chart shows riparian vegetation size classes for Redwood Creek Estuary and Skunk Cabbage Creek (Skunk Cabbage Creek Calwater planning watershed). Riparian vegetation is considered to be 90-meters (300 feet) on either side of the channel. This planning watershed had only 11% of the riparian in medium-large and greater trees, 31% in small-medium and smaller trees and 58% in non-forest as of 1994. Click on Picture to see an ArcView screen print of the Skunk Cabbage Creek Calwater planning watershed showing riparian vegetation class size. The information was derived from a 1994 Landsat image by the U.S. Forest Service. 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.
This analysis technique calculates averages of vegetation stands and more accurate at the stand rather than tree level. See Info Links for more information.
