Distribution

Pinus brutia, commonly known as the Turkish pine, is a species of pine native to the eastern Mediterranean region. The bulk of its range is in Turkey.

Turkish pine is also known by several other common names: Calabrian pine (from a naturalised population of the pine in Calabria in southern Italy, from where the pine was first botanically described), East Mediterranean pine, and Brutia pine.

Description[edit]

Pinus brutia is a medium-size tree, reaching 20–35 metres (66–115 feet) tall with a trunk diameter of up to 1 m (3+12 ft), exceptionally 2 m (6+12 ft). The bark is orange-red, thick and deeply fissured at the base of the trunk, and thin and flaky in the upper crown. The leaves (needles) are in pairs, slender, mostly 10–16 centimetres (4–6+14 inches) long, bright green to slightly yellowish green.

The cones are stout, heavy and hard, 6–11 cm (2+144+14 in) long and 4–5 cm (1+12–2 in) broad at the base when closed, green at first, ripening glossy red-brown when 24 months old. They open slowly over the next year or two to release the seeds, opening to 5–8 cm (2–3+14 in) broad. The seeds are 7–8 millimetres (1438 in) long, with a 15–20 mm (5834 in) wing, and are mainly wind-dispersed.

Varieties[edit]

Turkish pine is closely related to Aleppo pine, Canary Island pine, and Maritime pine, which all share many features with it. Some authors have treated it as a subspecies of Aleppo pine, but it is usually regarded as a distinct species. It is a moderately variable species, and the following subspecies and varieties are named:

  • Pinus brutia var. brutia (typical form; most of the range)
  • Pinus brutia var. pityusa (Georgia, adjacent Russian Black Sea coast, and Crimea; barely distinct from the type)
  • Pinus brutia var. pendulifolia (southern coastal Turkey; needles 20–29 cm or 7+3411+12 in, pendulous)
  • Pinus brutia var. eldarica (Afghan pine); Azerbaijan; Georgia; needles 8–14 cm or 3+145+12 in, cones 5–9 cm or 2–3+12 in).

The Eldar pine is treated as a species (Pinus eldarica) by some authors; it is adapted to a drier climate with a summer rainfall peak, whereas var. brutia, var. pityusa, and var. pendulifolia are adapted to a climate with mainly winter rainfall.

Taxonomy[edit]

Italian botanist Michele Tenore described the species in 1811.

Distribution and habitat[edit]

The bulk of its range is in Turkey, but it also extends to southeasternmost Bulgaria,[2] the East Aegean Islands of Aegean Sea, Crete, Crimea, Iran, Georgia, Azerbaijan, northern Iraq, western Syria, Lebanon and Cyprus.[3] It generally occurs at low altitudes, mostly from sea level to 600 m (2,000 ft), up to 1,200 m (3,900 ft) in the south of its range.

Ecology[edit]

Pinus brutia is a diagnostic species of the vegetation class Pinetea halepensis.[4]

The Krüper's nuthatch, a rare nuthatch, is largely restricted to forests of Turkish pine and depends heavily on it for feeding; the ranges of the two species are largely coincident.

P. brutia is resistant to the Israeli pine bast scale insect Matsucoccus josephi and is a major host for Thaumetopoea caterpillars.

The species covers 175,000 hectares (430,000 acres) in Cyprus, roughly ~90% of all woodland coverage on the island.[5] It forms ectomycorrhizal associations with numerous species of fungi, and its logs and branches are excellent substrates for many kinds of decomposing organisms.

Uses[edit]

Pinus brutia on the mountains near Aleppo

Honey[edit]

Turkish pine is host to a sap-sucking aphid Marchalina hellenica. Under normal circumstances, this insect does no significant damage to the pine, but is of great importance for the excess sugar it secretes. This sugar, "honeydew", is collected by honey bees which make it into a richly flavoured and valuable honey, "pine honey" (Turkish, çam balı), with reputed medicinal benefits.

Landmark[edit]

The "Lone Pine", a prominent landmark tree at an ANZAC First World War battle at Gallipoli, was this species. Cones from the battlefield were taken home to Australia, and plants sourced from the seeds were planted as living memorials.

"Lone Pine" memorials, based on cones brought back from Gallipoli, may use this species or Aleppo pine. Some memorials utilise other species altogether.[6]

Forestry[edit]

It is widely planted for timber, both in its native area (it is the most important tree in forestry in Turkey and Cyprus) and elsewhere in the Mediterranean region east to Pakistan. The timber is used for many purposes including carpentry, industry, general constructions, firewood and pulp.[7] In Israel it is sometimes preferred to the wider-used Pinus halepensis (Aleppo pine) because of its resistance to Matsucoccus josephi. It is also known for being well suited to recreational sites.

Cultivation[edit]

Pinus brutia is a popular ornamental tree, extensively planted in parks and gardens in hot dry areas (such as southern California, Utah, New Mexico and Nevada, as well as throughout Arizona and central Texas in the United States), where its considerable heat and drought tolerance is highly valued. The subspecies eldarica is the most drought tolerant form, used in Afghanistan, Iran and more recently in the Southwestern United States. In this region, P. brutia subsp. eldarica is referred to as "Eldarica pine", "Afghan pine" or "Mondell pine" (after Mondell Bennett, a commercial tree grower in New Mexico who popularized the species starting in 1969).[8]
