Sitka Spruce (Picea sitchensis) NON-NATIVE
This tallest of all the spruces
(up to 60-90 metres high in its native habitat) was introduced to Britain
from North America in 1831 and has become the most widely planted commercial
forest tree in the UK.
Over 45% of woodlands in Scotland consist of Sitka Spruce.
It is an evergreen, coniferous
tree which grows up to 45 metres in height. It is conical in shape, with the
upper
branches ascending, while lower branches drooping and heavier. It has smooth
bark which peels off in rounded flakes.
It is widely planted for commercial forestry and on a wide range of soils.
Male and female flowers are in seperate clusters towards the tips of branches near the top of the same tree.
Needles are sharp and stiff.
Woody, light brown, cylindrical cones are 5-8cm long, have crinkled scales and hang downwards.
USES:
Pale timber, which is fast growing, used
in the construction industry, packaging, pallets and paper making (pulp).
