Land Cover: USFS Veg Size in Lagunitas Creek Riparian Zones 1994 |
|
Caption: This chart shows vegetation size classes in 90-m riparian buffers in the Lagunitas Creek sub-basin, derived from a 1994 Landsat image by the U.S. Forest Service. Forested areas are dominated by small/medium trees. Kent Lake, San Geronimo and Upper Lagunitas have the highest large tree components in their riparian zones. Nicasio has the largest component of Non Forest, with the landscape in grasslands mostly used for pasture. The vegetation classification is accurate at a one-hectare scale and is suitable for stand classification. 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. See Map for the USFS Landsat riparian vegetation GIS layer and Info Links for more information.
