Where and how does the Sitka Spruce grow?

0

This conifer naturally grows on the west coast of North America . It has a very fast growth rate compared to some other trees. This means it can yield high volumes of timber in a comparatively short time. Foresters have developed models for growth or yield. The “yield class” figure is the mean cubic metres growth, for each hectare of tree species for each years growth. Sitka spruce has a yield class of 14 (14 cubic metres per hectare per year); Oak can be as low as 4. In terms of time, a Sitka spruce only needs to grow for 40 -60 years to reach its maximum timber potential. An oak can take up to and over 150 years. The Sitka Spruce has been grown commercially for timber especially in upland locations. Deep, moist and well drained soils are best for growth and so it flourishes in the North and West of the country on damper and elevated sites. Seeds dropped naturally from this conifer grow extremely well and at enormous rates; this “natural regeneration” is encouraged in many Forest site
