The browsed-class method has been developed to measure shrub utilization based on total weight of the plant. It uses growth form to place grazed shrubs into 6 browsed-classes. The method is fast, statistically sound, relatively free from personal bias, easy to learn and use, and can be used in research or land management. In a 10-year case study to determine proper use of hairy mountain-mahogany, plants were clipped initially and then reclipped once each year in the fall or winter over a 7-year period at 0, 10, 30, 50, 70 and 90% levels based on total weight of the plant. This was followed by a 2-year recovery study. Parameters studied were numbers, length, and production of twigs; area of live and dead crown cover; and general vigor and seed production. All criteria, except area of live crown cover, indicated that 50% of total weight was proper use of hairy mountain-mahogany.
