Distribution

Pinus brutia, commonly known as the Turkish pine and Calabrian pine, is a species of pine native to the eastern Mediterranean region. The bulk of its range is in Turkey, but certain varieties are naturalized as far east as Afghanistan.[2] It is also known as East Mediterranean pine, Afghan pine, and Brutia pine. The name "Calabrian pine" comes from an introduced grove in the Calabria region of southern Italy; historically this region was called Bruttium, which is likely where the specific epithet "brutia" comes from.[2] Pinus brutia bears many similarities with other, closely related species such as Pinus halepensis and Pinus canariensis. Turkish pine forms a species complex with the former.[3]

Description

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 1⁄2 ft), exceptionally 2 m (6 1⁄2 ft). The young bark is thin and red-orange, maturing to grey-brown to orange in color, fissured to flaky in texture. The leaves are needle-like, slender, 10–16 centimetres (4–6 1⁄4 inches) long, dark green to yellow-green.[2][4] The needles come in fascicles of two and rarely three,[2][5] the latter specimens showing similarities in cone structure to the related Pinus canariensis.[5]

The male cones are squat, 15–20 mm (0.59–0.79 in) long.[4][6] The female cones are short, with rigid, woody scales, 5–10 cm (2.0–3.9 in) long, 5–7 cm (2.0–2.8 in) broad, maturing from green to red-orange.[6][5] They most often appear in whorls of 3 to 4, and generally open within two years of fertilization.[2][6] The seeds are usually wind dispersed, dropping from the cones after they open, but some trees have been observed with cones that do not open enough to facilitate wind dispersal. Frankis believes Krüper's nuthatch assists these trees in dispersal.[2]

Varieties

Pinus brutia is closely related to Pinus halepensis, and female P. brutia cones have been shown to accept and hybridize with P. halepensis pollen. In the past it has been considered a variety or subspecies of P. halepensis.[5] The species is now treated as distinct, and forms a species complex across the Mediterranean with P. halepensis.[3]

  • Pinus brutia var. brutia: Typical form, with longer needles, 10–18 cm (3.9–7.1 in). Found across Eastern Mediterranean.[6]
  • Pinus brutia var. pityusa: Found in smaller stands along the eastern Black Sea coast, near Pitsunda. Very similar to var. brutia.[5][6]
  • Pinus brutia var. pendulifolia: Muğla, Turkey.[6] Exceptionally long needles, 24–29 cm (9.4–11.4 in), that hang in pendules similar to P. canariensis.[2]
  • Pinus brutia var. eldarica, Afghan Pine: native to Azerbaijan and Georgia and naturalized in Afghanistan and Pakistan.[2] Smaller cones, 5–8 cm (2.0–3.1 in).[6][7] Sometimes treated as a subspecies of P. brutia or a species of its own. Due to its tolerance of drought and poor soil, it is widely planted as an ornamental in both southwestern US and Europe.[6][8]

Taxonomy

Italian botanist Michele Tenore described the species in 1811. While Tenore did not provide an explanation for the specific epithet, Frankis believes Tenore named it after the historical region of Brutium, now Calabria, where an introduced population has become naturalized.[2]

Distribution and habitat

Pinus brutia on the coast of Thasos, Greece

The bulk of its range is in Turkey, but it also extends to southeasternmost Bulgaria,[9] the East Aegean Islands of Aegean Sea, Crete, Crimea, Iran, Georgia, Azerbaijan, northern Iraq, western Syria, Lebanon and Cyprus.[10] 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.[citation needed]

Ecology

Pinus brutia is a diagnostic species of the vegetation class Pinetea halepensis.[11]

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.[citation needed]

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.[12] It forms ectomycorrhizal associations with numerous species of fungi, and its logs and branches are excellent substrates for many kinds of decomposing organisms.

Uses

Honey

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

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.[13]

Forestry

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.[14] 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

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).[15]
