Topic USFS Riparian Tree Size Classes: Lower Marshall Cr CalWater 1994
 
Caption:  This bar chart shows vegetation and timber types of the riparian zone of the Lower Marshall Creek Calwater planning watershed. The U.S. Forest Service derived the information from a 1994 Landsat image. This analysis technique calculates averages of vegetation stands at a one-hectare scale. With 66% of the riparian zone composed of stands of trees less than 12 inch diameter there is ample opportunity for stream warming, although this condition may be due to geologic terrain and natural grasslands in some areas. Scroll down for a key to classifications. Vegetation classifications are: Very Large Trees = >40" in diameter Large Trees = Trees 30-39.9" in diameter Medium/Large Trees = 20-29.9" in diameter Small/Medium Trees = 12-19.9" in diameter Small Trees = 5-11.9" in diameter Saplings = Trees less than 5" Non-Forest = No trees, shrubs, grass, bare soil
