The ability of forest shrubs to maintain a dense stable cover, once they are established, has important implications for the development, structure, and species composition of forest stands. However, little work has been done to document how this cover is maintained. A recently retired FRESC scientist co-authored a publication in which the vegetative stem production of salmonberry and salal (two common clonal shrubs in Oregon) were monitored for eight years and five years, respectively. The results show that both salmonberry and salal maintained stem density by annual production of new aerial stems on rhizomes and at the base of older aerial stems. Not many of the stems that were produced survived. However, enough survived to replace old, large stems that died, and thus maintain the shrub cover. Annual stem production occurred in thinned and unthinned stands, in hardwoods, and in stands in both riparian and upland sites. Similar to other studies, no tree regeneration was observed in plots under either salmonberry or salal. Sprouting ability may be reduced if overstory tree density is high or if trees can become established immediately following a treatment and quickly overtop the shrubs.
