Scots Pine
Family:
Pinaceae (Pine family).
Scots Pine is the only native British Pine.
Habitat:
This tree may be one of the most common trees in the Taiga or Northern
Hemisphere Forest since it ranges, at all altitudes, all the way to East Siberia
and goes down south as far as the Balkans and the Black Sea.
Scots Pine is a pioneer species and has the ability to regenerate and thrive in
poor soils. Planted specimens can be found throughout Britain, but the last small remnants
(about 1% old growth) of the once great Caledonian Pine Forest are found in
Scotland. There has been a growing trend in Scottish Forestry to allow Scots
pine regeneration and also to plant it in conjunction with deciduous native
species such as Birch. Natural stands of Scots pine can also be found in the
heath lands of Southern England.
Characteristics:
The young trees have a more narrow conical outline. As the trees grow, they
loose their lower branches and the crowns becomes flatter with wide spreading
branches. Against the horizon the crowns can look like small dark green clouds
floating around the tops of the tree. Height up to 120 ft or 36m. Maximum girth
in a mature tree can be up to just over 8 ft or 2.5m
The upper bark is a warm orange-red colour and the lower bark is usually deeply
fissured in older trees. The blue-green needles are usually twisted. They grow
in pairs and are 5-8 cm long.
The small pointed hanging cones are greyish-brown with woody scales and produce
winged seeds when the scales are opened. You can see cones in various stages on
the branches. The ones nearest the tip are the most recently fertilised flowers,
then there is a pair of two year old cones maturing further down and a bit
further along again you find the lowest cones, which are three years old. These
last cones are ripe and will probably have opened scales.
The life-span of Scots Pines is about 250-300 years, although older specimens
have been found, including a 520 year old tree.
Cultivation:
Propagation is usually by seed. Collect cones in winter or early spring. Let the
cones dry. Extract the seeds and put in a cold store. It will remain viable for
several years.
Growth: 40 ft in 20 years
Can be very susceptible to dry rot fungus.
Wood:
The timber of Scots pine is also known as "red deal". Although it is a soft
wood, it is strong and easy to work. These qualities have made it a popular
choice for a great variety of uses.
When untreated it is not naturally durable wood, but it takes preservatives very
well.
In the past it was used for building purposes, ships masts and as a major source
for turpentine, resin, and tar. It was also used for making charcoal and flaming
torches.
Nowadays its main uses are for building wood, pit-props, telegraph poles,
fencing, furniture, boxes, chipboard and paper pulp.
