Spruce continues to maintain height growth longer than hemlock and lives longer. Few hemlock live more than 500 years; Sitka spruce may live to 700 or 800 years. Very old spruces eventually assume a dominant position in old-growth hemlock-spruce stands. Sitka …

2023年10月18日 · From spreading monoculture plantations across the wilds of Scotland to clear-felling ever scarcer old growth forests in North America, Sitka sits in the eye of the storm of differing demands and perspectives about forests.

Thin panels of slow-growth Sitka spruce are highly resonant, making them desirable for piano sounding boards. Wood from young, managed stands generally lacks the knot-free, slow-growth characteristics of old-growth trees. Experience from the United Kingdom, where Sitka spruce has been extensively planted, shows that the
