Topic	USFS Riparian Veg Types: Sub-Basin Summaries

 

Caption:  This bar chart shows 90-meter wide riparian zone vegetation size classes for Redwood Creek sub-basins. Note the vegetation size difference between the sub-basins: Prairie Creek sub-basin has the greatest extent of large trees, Lower Redwood sub-basin has the greatest diversity of tree class sizes, Middle Redwood sub-basin is skewed towards medium and smaller sized trees, and Upper Redwood sub-basin has the greatest extent of small trees. The information was derived from a 1994 Landsat image by the U.S. Forest Service. This analysis technique calculates averages of vegetation stands and is accurate at the tree stand level. 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, prairie, and/or bare soil.
