Description: The estimation of herbage production and· utilization in browse plants has been a problem for many years. Most range technicians have simply estimated the average length of twigs or leaders. then expressed use by deer and livestock as a percentage thereof based on the estimated average length left after grazing. Riordan used this method on mountain mahogany (Cercocarpus montanus Raf.) and service berry (Amelanchier utahensis Koehne) and found that reliable estimates were virtually impossible. Measurements of 10,000 to 20,000 twigs or leaders were necessary with these two species for a reliable estimate of average length.
