    Picea sitchensis is often found on moist well-drained sites such as alluvial floodplains, marine terraces, and headlands (Pojar & MacKinnon ). This species prefers full sun and is intolerant of shade and atmospheric pollution. Sitka spruce grows in pure stands, more often mixed with western hemlock, Douglas fir, western redcedar, yellow cedar, grand fir, red alder, and black cottonwood. Sitka spruce is the glory of sound board wood, which is why Brent's products are in demand by everyone from big names like Gibson to independent string-instrument crafters across the globe. To demonstrate the quality of this wood for sound production, Annette pinched a ‘½ sound board set' between her thumb and forefinger and let the wood hang.

The amount of stem decay in live trees is correlated with tree age for both Sitka spruce and western hemlock in southeast Alaska (Figure 3) (Kimmey, ).

The high level of stem decay can be attributed to the abundance of old trees that grow in these forests which are not affected by fire and infrequently experience stand-replacing by: title = {Site index and height growth curves for unmanaged even-aged stands of western hemlock and sitka spruce in southeast Alaska / }, volume = {no}, copyright = {Not provided.

In the larger size classes, between m and m, however, the age ranges in each size class were more variable in general, especially for hemlock.

For example, ages of western hemlock in size class 6 ranged from 14 to years, whereas ages for Sitka spruce ranged from 8 to 31 years (table 4).

Mill lengths were and feet for Sitka spruce and and feet for western hemlock, which included a 6-inch trim allowance. A total of 1, mill-length logs were produced from the trees selected, an average of about 5 mill-length logs per tree.

The effects of partial cutting on tree size structure and stand growth were evaluated in 52 plots in 13 stands in southeast Alaska that were partially harvested 53–96 years ago and compared with year-old even-aged stands that developed after clearcutting.

The net basal-area growth was greater in the partially cut plots than in the uncut plots, and basal-area growth generally increased Cited by: 7. The effects of partial cutting on species composition, new and residual-tree cohorts, tree size distribution, and tree growth was evaluated on 73 plots in 18 stands throughout southeast Alaska.

Tsuga heterophylla and Picea sitchensis were felled in sixty-seven 1/5-acre plots and tree volume and extent of internal decay were determined. Regression analysis was used to predict % decay in standing trees from external indicators, tree characteristics and environmental variables.

Lumber sawn from young-growth Sitka spruce and western hemlock in southeast Alaska appears to be best suited for structural light framing or molding and millwork based on visual grading rules and mechanical properties observed.

In this study, which applied export standards, more than 90 percent of the lumber was graded as No. 2 or better. Mountain hemlock communities in the western Cascades of Oregon and Washington commonly have a mixture of other tree species; estimated productivity ranges from to m³/ha (54 to ft³/acre) per year (8,38).
