Area	Lower Trinity/Basin-wide
Topic	Map: 1G. USFS Riparian Vegetation Size, Trinity Basin

 

	This is a map of 1999 USFS Landsat vegetation size data within 90-meter riparian buffer zones in the Trinity basin. Not surprisingly, reaches of streams flowing through grasslands often have Non-Forest riparian zones. This may be partially due to timber harvest, grazing and agricultural management practices. Data provided by the U.S. Forest Service Spatial Analysis Lab in Sacramento, CA. The vegetation classification is accurate at a one-hectare scale (approximately 11 pixels) and is suitable for stand classification.
