The Determination of Increment in Cut-Over Stands of Western Yellow Pine in the Southwest

The irregular stocking, uneven-aged character and lack of uniformity of size and age classes in western yellow pine stands in the Southwest, make growth data obtained from sample plots unreliable. The author offers a different method based on a representative stand table, data for which must be ample and should be collected on long, narrow strips, and on the periodic remeasurement of only a definite number of trees of each diameter class.
