Juniperus tibetica (Tibetan juniper) is a species of juniper, native to western China in southern Gansu, southeastern Qinghai, Sichuan, and Tibet, where it grows at high to very high altitudes of 2,600–4,800 metres (8,500–15,700 ft).
It is an evergreen coniferous shrub or small to medium-sized tree growing to 5–15 metres (16–49 ft) (rarely 30 metres (98 ft)) tall, with a trunk up to 2 metres (6 ft 7 in) diameter. The leaves are of two forms, juvenile needle-like leaves 5 millimetres (0.20 in) long on seedlings and occasionally (regrowth after browsing damage) on adult plants, and adult scale-leaves 1.5–3 millimetres (0.059–0.118 in) long on older plants; they are arranged in decussate opposite pairs or whorls of three. The cones are ovoid, berry-like, 9–16 millimetres (0.35–0.63 in) long and 7–13 millimetres (0.28–0.51 in) diameter, Blue-black, and contain a single seed; they are mature in about 18 months. The male cones are 1.5–2 millimetres (0.059–0.079 in) long, and shed their pollen in spring. It is usually monoecious (male and female cones on the same plant), but occasionally dioecious (male and female cones on separate plants).
Conservation and Uses
It is the only woody plant occurring over large areas of high altitude Tibet, and grows very slowly in the harsh climatic conditions there. The wood is therefore of major importance to local communities for building construction and fuel, and is also burnt for incense. The foliage is also heavily browsed by domestic goats and other livestock. Both uses have resulted in a significant decline in the species' abundance; formerly listed (1998) as not threatened, it has more recently (2005) been re-categorised as Near Threatened.
From Wikipedia, the free encyclopedia
Does anyone know if this species is being grown anywhere in the US? I am seeking seeds or plants. I see that specimens exist in the UK so they are being grown at low altitudes.
