    For instance, Ryan and Reinhardt found that the probability of fire-caused mortality in Douglas-fir with 1-cm-thick bark was if 10% of crown volume was scorched by fire, and if 30% was scorched; tree survivorship increased by 40% and %, respectively, for a tree with 3-cm-thick bark.

Tree ages are also variable in old-growth Douglas-fir for-ests in the western Cascades (Franklin and Waring ; Means ). For example, Means () found two dry-site Douglas-fir stands with trees ranging in age from 80 to years. He concluded that the broad range of ages was the result of periodic fires that killed only some of the.

It discusses the biological importance, social significance, and management of old-growth as well as late-succession forests. This volume will be of interest to public officials, policymakers, the forest products industry, environmental advocates, researchers, and concerned residents.

We characterized the structure of 91 old-growth forests dominated by Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), using inventory data from recent (a??) old-growth timber sales in western Oregon.

The data were complete counts (i.e., censuses) of all live trees >20 cm diameter at breast height (dbh, measured at m above the ground) over a mean area of ha at each site. Douglas-fir basal area levels and trends were similar between models. Goslin also found good agreement between simulated and actual basal area levels of Douglas-fir over the first years of stand development.

The simulationsCited by: Tree population dynamics, growth, and mortality were determined in old-growth forested watersheds in the Hoh River valley, Olympic Peninsula, Washington: West Twin Creek (elevation – m) and Hoh Lake (elevation – m). Principal tree species at West Twin Creek are Douglas-fir (Pseudotsugamenziesii (Mirb.)Cited by: (A.

Old-growth Douglas-fir (Pseudotsuga menziesii) trees are a significant though minor component of most old-growth redwood (Sequoia sempervirens) forests in the Santa Cruz Mountains, sharing the canopy with redwoods.

Unlike redwood, they succumb readily to such tree-damaging agents as disease, insects, windfall, and wildfire. generally leave remnant old-growth trees, damaged trees, and large or rare hardwoods.

JDSF is 20, ha of primarily second and third-growth redwood and Douglas-fir forests. Under a new management plan, old-growth reserves and individual old-growth trees (trees present before the. The Douglas fir (Pseudotsuga menisci) is an ornamental tree that is also widely utilized as a Christmas tree.

It claims a medium rate of growth; a medium growth rate, according to the Arbor Day Foundation, signifies a tree that grows between 13 and 24 inches in height annually. ~~,~, Forest Ecology ~,~ ~,~ and ~;~ ~,~.II~.~Y~' ~ Management E LS EV I ER Forest Ecology and Management 70 () Branch mortality and potential litterfall from Douglas-fir trees in stands of varying density Douglas A.
