Topic	Land Cover: USFS Veg Size in Riparian for Ray Gulch 1994

 

Caption:  This bar chart shows riparian vegetation size classes for the Ray Gulch 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 and only 44% of the riparian in this Calwater was greater than 20 inches in diameter (Medium-Large, Large), which indicates low large woody debris recruitment potential to streams (see Hypothesis #3). Click on Map to see spatial data. 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.
