Topic	USFS Riparian VegTypes: Twin Lakes Creek 1994

 

Caption:  This bar chart shows riparian vegetation size classes for Twin Lakes Creek Calwater in the Upper Redwood Creek sub-basin. Riparian vegetation is defined here as 90-meters (300 feet) on either side of the channel. This planning watershed had 18 percent of the riparian in medium-large and greater trees, 70 percent in small-medium and smaller trees, and 12 percent in non-forest as of 1994. Click on Picture to see an ArcView screen print of the 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.
