Lebanese cedar

Description

Cedrus libani, the cedar of Lebanon or Lebanese cedar, is a species of tree in the pine family, native to the mountains of the Eastern Mediterranean basin. It is a large evergreen conifer that has great religious and historical significance in the cultures of the Middle East, and is referenced many times in the literature of ancient civilisations. It is the national emblem of Lebanon and is widely used as an ornamental tree in parks and gardens. Cedrus libani can reach 40 m (130 ft) in height, with a massive monopodial columnar trunk up to 2.5 m (8 ft 2 in) in diameter. The trunks of old trees ordinarily fork into several large, erect branches.The rough and scaly bark is dark grey to blackish brown, and is run through by deep, horizontal fissures that peel in small chips. The first-order branches are ascending in young trees; they grow to a massive size and take on a horizontal, wide-spreading disposition. Second-order branches are dense and grow in a horizontal plane. The crown is conical when young, becoming broadly tabular with age with fairly level branches; trees growing in dense forests maintain more pyramidal shapes. C. libani var. libani is endemic to elevated mountains around the Eastern Mediterranean in Lebanon, Syria, and Turkey. The tree grows in well-drained calcareous lithosols on rocky, north- and west-facing slopes and ridges and thrives in rich loam or a sandy clay in full sun. Its natural habitat is characterized by warm, dry summers and cool, moist winters with an annual precipitation of 1,000 to 1,500 mm (39 to 59 in); the trees are blanketed by a heavy snow cover at the higher altitudes. In Lebanon and Turkey, it occurs most abundantly at altitudes of 1,300 to 3,000 m (4,300 to 9,800 ft), where it forms pure forests or mixed forests with Cilician fir (Abies cilicica), European black pine (Pinus nigra), Turkish pine (Pinus brutia), and several juniper species. In Turkey, it can occur as low as 500 m (1,600 ft).
