To describe the growth of whiteleaf manzanita (Arctostaphylos viscida Parry) on a variety of sites, stem-analysis techniques commonly used to analyze height growth of trees were applied to 47 open-grown shrubs in southwestern Oregon. Present crown dimensions were measured, and past stem lengths for each year of growth were determined by dissecting the longest stem. A model was fit to describe stem length as a function of plant age and stem length at age 10. Stem height, crown area, and crown volume were then related to length of the longest stem. The resulting equations can be used to predict the growing space that will be occupied by open-grown shrubs at any time through age 20. FOR. SCI. 34(4):1094-1100.
