   Caption:  This bar chart shows riparian tree size class of the Bridge Creek Calwater planning watershed.  The U.S. Forest Service derived the information from a 1994 Landsat image.  This analysis technique is accurate at the stand rather than individual tree level.  Scroll down for a key to classifications.  Click on Picture to see an ArcView screen capture of the Bridge Creek Calwater planning watershed showing vegetation types.  Vegetation is classified according to diameter at breast height (DBH):
Giant = >50" DBH,  V Large = 40-50" DBH, Large = 30-40" DBH,  Medium/Large = 20-30" DBH,  Small/Medium = 12-20" DBH,  Small = 5-12" DBH, Non-Forest = No trees, shrubs, grass, bare soil.
