Abstract:

At two sites in southwestern Oregon, stands of tanoak (Lithocarpus densiflorus) were thinned in the second year after sprouting (1983) to create relative covers of 25, 50, or 100% of that for unthinned stands. At one site, relative covers were replicated with and without suppression of understory vegetation. Height, crown width and dominant-stem diameter were measured annually on each of 135 sprout clumps of tanoak from 1983-1988. Reductions in relative cover caused a proportionate increase in mean relative growth rate (RGR) of tanoak; however, the effect of understory suppression was not consistent. Increases in RGR of individual clumps from thinning were considerably greater for crown width (73% and 43% for large and small clumps, respectively) than for height (28% and 22%). Predicted crown width of tanoak 6 yr after thinning and understory suppression was up to 46% greater than that of clumps in untreated stands. West. J. Appl. For. 9(4):101-105.
