Pinus mugo
Pinus mugo, known as creeping pine,dwarf mountainpine,mugo pine,mountain pine, scrub mountain pine or Swiss mountain pine, or is a species of conifer, native to high elevation habitats from southwestern to Central Europe.
Distribution
Pinus mugo is native to the Pyrenees, Alps, Erzgebirge, Carpathians, northern Apennines, and higher Balkan Peninsula mountains. It is usually found from 1,000–2,200 m (3,281–7,218 ft), occasionally as low as 200 m (656 ft) in the north of the range in Germany and Poland, and as high as 2,700 m (8,858 ft) in the south of the range in Bulgaria and the Pyrenees.
Subspecies
There are three subspecies:
Pinus mugo subsp. mugo — in the east and south of the range (southern & eastern Alps, Balkan Peninsula), a low, shrubby, often multi-stemmed plant to 3–6 m (10–20 ft) tall with symmetrical cones.
Pinus mugo subsp. uncinata — in the west and north of the range (from the Pyrenees northeast to Poland), a larger, usually single-stemmed tree to 20 m (66 ft) tall with asymmetrical cones (the scales are much thicker on one side of the cone than the other).
Some botanists treat the western subspecies as a separate species, Pinus uncinata, others as only a variety, Pinus mugo var. rostrata. This subspecies in the Pyrenees marks the alpine tree line or timberline, the edge of the habitat at which trees are capable of growing.
