Pinus nigra maritima – Corsican Pine
Pinus nigra maritima commonly known as Corsican Pine is native to North America and Europe. It is fast-growing and lightly branched conifer. It is moderately fast growing tree, at about 30-70 cm (12-28 inch) per year.Also it is a large evergreen tree, growing to 20-55 meters (66-180 ft) high at maturity and spreading to 6-12 (20-40 ft) wide. The young twigs are yellowish-brown and ridged. Later they become much roughened by the persistent needle bases. The light brown, resinous buds are up to 2.5 cm long, and are broad at their base, suddenly tapering to a sharp point. The young shoots stand upright in May and June like white-green candles. The needles are grayish-green or sage-green, 8-13 cm long, in pairs, bound together at their base by a grey sheath consisting of membranous scales. They are often twisted and are stout and densely arranged on the shoots.
The flowers of both sexes are found on the same tree. The male catkin-like flowers lie at the base of the young shoot and are yellow at the time of pollination. The red females at the tips of new shoots are minute cone-lets which later expand to asymmetrical cones 3-5 cm in length, becoming shiny, hard and mid-brown; the raised portion of each scale (the umbo) bears a knob. The cones open in the spring or summer of the second year after fertilization and release winged seeds.
The rough, grayish to dark brown bark is fissure and flakes off. The branches are whorled, often at wide intervals. The wood is resinous and has reddish heartwood surrounded by pale brown sapwood. It is adjudged to be inferior to that of Scots Pine, but can be used for similar purposes. Though not naturally durable, it takes preservative well.
Silviculturists know the tree as a wind-farm, fast grower and heavy volume producer in Europe. It is one of the most productive species on the sandy soils in the north-west Europe. Only strains Corsica are recommended today.
Austrian Pine, P. nigra Arnold, has a more coarse, rugged, less straight appearance than Corsican Pine. Its timber is coarse, knotty and usually valueless, but as the tree is hardy and wind-firm it is useful as a shelter belt, especially along the coast. 
The Corsican Pine is also planted as a street tree, and as an ornamental tree in gardens and parks in USA, Canada, Europe, Australia and many more countries.

Pinus Contorta commonly known as Lodgepole Pine is native to North America. It’s a two-needled conifer. The name ‘Lodgepole’ is derived from its use by Indians as poles to support their wigwams or lodges.

The twigs are orange-brown to black wrinkled when young. The long buds are cylindrical, resinous and blunt. The young shoots stand upright in May and June like emerald candles. The needles are stiff and in pairs, bound together at their base by a sheath consisting of membranous scales.
They are of similar length about 2-5 cm to those of Scots Pine but are stouter slightly twisted and yellowish-green or mid-green. The foliage tends to be dense with much overlapping of needles in trees of American costal provenances.
The flowers of both sexes are found on the same tree and they are produced from the second year of life. The males are rather dense clusters of yellow to orange globules and the females (terminal on new shoots) are small and crimson, soon becoming reddish-purple, plum-colored and spiky cone-lets. The cones on inland and northern provenances of Lodgepole Pine are often at a node two-third of the way up the year’s shoot; but the coastal provenances are rarely bi-nodal in growth. The cone points down the shoot, is somewhat egg-shaped, about 4 cm in length and the raised portion of each scale (the umbo) bears a small sharp prickle.
The bark is rather odd, being a dull brownish-black and broken into small squarish plates divided by shallow furrows, or closely scaly. The heartwood is a pale straw color and there is very little contrast between heartwood and sapwood. The timber has proved a satisfactory alternative to Scots Pine for roofing, flooring, interior framing, and other joinery. Thinnings are used for paper pulp, chipboard, poles and pit-props.

In the last twenty years Lodgepole Pine has been planted on an ever-increasing scale in Scotland and North Wales because of its remarkable tolerance of poor soils, including the peaty moorlands of the wetter and cloudier western districts. Under comparable conditions it grows significantly faster than does Scots Pine and leading shoots of 5 feet may be seen.
