Pinus nigra
Ecology
P. nigra is found in plantations, shelter-belts, parks, churchyards and large gardens, locally becoming naturalised on heaths and sand dunes. Subsp. nigra prefers light soils; subsp. laricio tolerates a wider range of soils. Regeneration from seed is frequent. Lowland.
Status
Trends
Subsp. laricio was introduced in 1814, subsp. nigra in 1835; the former was known in the wild by 1905 and the latter by 1951. P. nigra is preferred to P. sylvestris for forestry in S. Britain, where it has become widespread on heaths.
World Distribution
The species is a native of S. Europe, N. Africa and S.W. Asia. Subsp. nigra occurs in Austria, Italy and the Balkans and subsp. laricio in Corsica, S. Italy and Sicily.
