Pinus luchuensis, commonly called Luchu pine [2] or Okinawa pine, [2] is a species of conifer in the family Pinaceae endemic to, and locally abundant in the Ryukyu Islands of Japan. [1] [2] It was once threatened by habitat loss in the wild, where it can be found growing in small stands near windy ocean shores. [1] Having been harvested widely since the Second World War, the remaining stands are no longer commercially viable, [1] except when cultivated for ornamental use. [2]

<i>Pinus sylvestris</i> Species of conifer in the family Pinaceae

Pinus sylvestris, Scots pine (UK), Scotch pine (US), European red pine, or Baltic pine is a species of tree in the pine family Pinaceae that is native to Eurasia, ranging from Western Europe to Eastern Siberia, south to the Caucasus Mountains and Anatolia, and north to well inside the Arctic Circle in Fennoscandia. In the north of its range, it occurs from sea level to 1,000 m (3,300 ft), while in the south of its range it is a mountain tree, growing at 1,200–2,600 m (3,900–8,500 ft) altitude. It is readily identified by its combination of fairly short, blue-green leaves and orange-red bark.

<i>Pinus peuce</i> Species of plant

Pinus peuce is a species of pine native to the mountains of Macedonia, Bulgaria, Albania, Montenegro, Kosovo, the extreme southwest of Serbia, and the extreme north of Greece, growing typically at (600-) 1,000-2,200 (-2,300) m altitude. It often reaches the alpine tree line in this area. The mature size is up to 35–40 m height, and 1.5 m trunk diameter. However, the height of the tree diminishes strongly near the upper forest limit and may even obtain shrub sizes.

<i>Pinus contorta</i> Species of plant

Pinus contorta, with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines, it is an evergreen conifer.

<i>Pinus taiwanensis</i> Species of conifer

Pinus taiwanensis, the Taiwan red pine, is a species of conifer in the family Pinaceae. It is found only in Taiwan. It is a close relative of Pinus luchuensis of Japan and Pinus hwangshanensis of China, sometimes considered as a subspecies of the former. Sometimes Pinus hwangshanensis from China are also referred to as P. taiwanensis. Pinus taiwanensis var.fragilissima and P.taiwanensis var.taiwanensis are the two varieties of this species. Taiwan red pine is a large tree, with a straight trunk up to 35 m (115 ft) tall and 80 cm (2.6 ft) in diameter. Needles are in bundles of two. Cones are 6–7 cm (2.4–2.8 in) long.
