WebEach method presented here is in effect a short-cut from which one or more watershed characteristics have been omitted. It is a good practice to consider more than one method, choosing the one that best fits the characteristics of a given watershed. It is not worthwhile averaging estimates made using two or three methods. Instead, the method that WebNRCS, MD November, 2006 Vegetative manipulations to restore plant diversity and provide for wildlife habitat shall be accomplished by mowing, burning, light disking, selective cutting, prescribed grazing, planting of annual food plots, or a combination of these methods, as appropriate.
