Pseudotsuga Menziesii – Douglas Fir
Pseudotsuga Menziesii commonly known as Douglas Fir. It is a magnificent, large and important tree of western North America, was discovered by Archibald Menzies, a Scottish botanist, in 1791 on the west coast of Vancouver Island. David Douglas another Scottish botanist, sent seeds to England in 1822, and the tree now ranks as a major species in British forestry, particularly so far as speed and quantity of growth, and strength of wood are concerned. The tree is not a true fir: its cones are pendent whereas those of true firs stand erect.
P. menziesii is medium-size to extremely large evergreen trees, 20–100 m (70–330 ft) in height.
The young shoots are yellowish-green (some dark pink, briefly), turning grey as they age. The brown papery buds are shiny, long and spindle-shaped, and always non-resinous. The needles are soft, disposed on a flat plane, and are deep green on top, with a groove; underneath they show two grey bands of stomata on either side of a prominent midrib. They taper towards the apex, and when pulled away from, the twig they leave a smooth round scar, not a peg. The soft new pale green needles which appear in June fringe the edges of all the branches, giving the tree its best appearance.
Both sexes of flowers are found on the same tree. The male catkins are mostly pendulous and in groups; they are brownish or dull red at first, turning yellow at pollen time. The female flowers are at first erect, with soft green scales and long pointed bracts, which are usually crimson or pink. They hang down when developing into the 5 – 8 cm cones which become pale-brown, with papery three-pronged bracts peering out from each scale. Winged seeds fall in mid-autumn.
The bark is at first greyish-black and smooth, with some blisters holding fragrant resin, but eventually becomes reddish-brown, thick and corky, deeply ridged and fissured, with orange-brown tints in the cracks. The sapwood is pale creamy-brown and heartwood pinkish-brown, darkening with age. The wood is coarse in texture, fairly hard, straight-grained, resinous, strong and heavy, providing an excellent constructional, flooring, and joinery timber, as well as one having many ther uses which include fencing, pit-props, paper pulp, and telegraph poles.

Silviclturists appreciate Douglas Fir’s quick growth and heavy volume, but take care not to plant it on infertile ground or where wind blow may result. It is only seen at its best on deep well-drained soils in fairly sheltered situations. A specimen at Powis Castle near Welshpool in Mont-gomeryshire rises about 180 feet – one of the tallest trees in Britain.
The Colorado or ‘Blue’ Douglas Fir, P. menziesii glauca Franco, is a smaller and slower growing tree with bluish foliage that smells of turpentine when crushed. This species is not satisfactory in Europe, and is planted only as a slow-growing ornamental tree.

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.
