Pinus sylvestris – Scots Pine
Pinus sylvestris commonly known as Scots Pine and HardyScots Pine. It is well known by its pale red bark towards the top of the tree and its contrasting blue-green foliage, is Britain’s and Europe’s only native conifer grown for timber production. The species is mainly found on poorer, sandy soils, rocky outcrops, peat bogs or close to the forest limit. This is a long living tree and lifespan is normally 150–300 years, with the oldest recorded specimens in Lapland, Northern Finland over 760 years. P. sylvestris is an evergreen coniferous tree growing up to 35 m (115 ft) in height and 1 m trunk diameter when mature, exceptionally over 45 m (148 ft) tall.
The buds are reddish-brown, up to 1.5 cm long, narrow and blunt. The young shoots stand upright in May and June like white-green candles, smooth and shiny. Later they lengthen and turn green, becoming greyish or yellowish-brown. The stiff, blue-green needles, about 2.5 to 5 cm or more long, are in pairs, bound together at their base by a grey sheath consisting of membranous scales.

The flowers of both sexes are found on the same tree. The male flowers are small, globose catkins tightly clustered and set some way back from the tips of the twigs; at first dull red, they become golden at pollen time. The tiny female conelets are green with crimson ends to their scales, and appear in May at the very tips of newly expanded shoots. After fertilization they grow during the nest year into small green round structures. Later they become hard, woody, greyish-brown cones which are symmetrical, ‘pointed’, and about 4 cm long; the raised portion of each scale (the umbo) bears a knob. The cones mature in two years, and winged seeds fall in spring. On some trees there will be found not only one year and two year old cones, but also three years old, open and empty.
The bark at the base is fissured, forming irregular, longitudinal plates which are reddish or grayish-brown. The shining orange-red bark of the upper part of the tree is a distinct and warming feature. When young, the tree is conical and well mature, it is usually sparsely branched with a flat or domed crown.
The timber is resinous and has a distinct reddish heartwood surrounded by pale-brown sapwood. Its many uses include telegraph poles, railway sleepers, fencing, construction work, pit-props, boxes, wood wool, paper pulp, and chip-board. Though not naturally durable, it takes preservative well. In the timber trade the wood is often referred to as ‘fir’, ‘deal’ or ‘redwood’, usually qualified in some way.
Scots Pine is now found in its wild state only in Scotland, but has been extensively planted throughout Europe; it grows readily from self-sown seed on heaths in many southern counties. It is most successful in the warmer and drier districts towered the south and east.
As a shelterbelt tree, this pine has proved successful in the south and east and at low elevations elsewhere.

Pinus strobus –  White Pine
Pinus strobus commonly known as Weymouth Pine also known as Eastern White Pine. It’s a vive-needled conifer of the eastern half of North America, now found sparsely throughout Europe, and was introduced in the eighteenth century by Lord Weymouth on his Longleat estate near Bath. It is reputed to have been first grown at Badminton, Gloucestershire, by the Duchess of Beaufort in 1705. It was the first conifer planted in the Forest of Dean. Fine needles and banana-shaped cones make this an interesting tree, but one which is frequently ruined by a rust fungus and by bark aphids.
P. strobus is one of the long living tree. Mature trees are living 200-250 years, sometimes it can lives more than 400 years. It grows approximately 1 M (3.3 ft) yearly between the ages of 15 to 45 years. It is the tallest tree in Easter North America. It grows 50-58 M (168-188 ft) in height. Sometimes it grows up to 70 m (230 ft) tall.
The young shoots are slender and green, later turning greenish-brown becoming roughened by the scars left by fallen needles, but much smoother than two-needle pines. The small resin-coated buds are sharply pointed and greyish-brown. The five pendent needles are thin, 7-13 cm long, blue-green or bluish-grey, and bound together at their base by a sheath consisting of membranous scales.
The flowers of both sexes are found on the same tree. The male catkins are about 1 cm long and are in small clusters, yellow when ripe. The slender female flowers are about 2 cm long, pink with purple scale margins. When young the cones are green, later becoming brown. They are pendent, slightly curved (banana-shaped), up to 15 cm long, their widely separated scales sometimes coated with white blobs of resin. Heavy crops of cones only occur at intervals of from four to seven years.
The bark on young stems is smooth and green or greenish-brown, later becoming dark grey, rough, and deeply fissured into broad, scaly ridges on the lower part of the trunk. The wood is pale brown, light, soft, and fine textured, suitable for joinery and general purposes.
The tree would undoubtedly be a fine timber-producer in southern America and Europe but for the attack of a rust fungus, Cronartium fibicola, which causes ‘blisters’ on the pine shoots and at another stage attacks black-currants and gooseberries. As it is, the tree is now rarely planted.
