Pinus brutia Seeds | Brutia Pine

Brutia Pine (Pinus brutia) seed
Brutia Pine (Pinus brutia): Pinaceae; genus Pinus , in the two-needled hard pines, native to Eastern Mediterranean — southern Italy and Sicily, Greece, Crete and the Aegean islands, Cyprus, Turkey, western Syria and Lebanon, with outlying stands in the Crimea, the Caucasus and the Eldar plain of Azerbaijan.

LATIN NAME: Pinus brutia

COMMON NAME: Brutia Pine

Plant Profile

From the Aegean coast of Turkey to the hills behind Beirut, the dry lower slopes are governed by one tree, and it is not the familiar Aleppo pine of the western basin. Brutia pine is the eastern vicariant of that species: it takes the hotter and more fire-prone end of the Mediterranean, grows faster and straighter, and forms the extensive coastal forests that give the region its grey-green light.

The needles grow two to a fascicle with a persistent sheath at the base, and they are long and bright green. Cones are carried in whorls of two to four on short stalks, ripening to a glossy brown with a prominent, pyramidal umbo and a small prickle on each scale. The cones sit in tight rings around the stem, so a mature tree is easy to pick out at a distance.

The bark is the tree’s insurance policy. It is thick and deeply fissured, reddish at the base, and insulates the cambium well enough that a moderate fire kills the foliage without killing the trunk, so the tree refoliates from surviving buds rather than starting again from the ground. Where a fire does kill the stand, the tree rebuilds from seed: cones release their winged seed onto bare mineral soil cleared of litter and competitors.

Distilled from the foliage, Brutia pine oil is overwhelmingly monoterpene, with alpha-pinene usually dominant and beta-pinene, myrcene and limonene making up much of the balance, plus the sesquiterpene beta-caryophyllene. The profile shifts with provenance, altitude and season, which makes the oil a useful fingerprint in provenance research as well as a raw material for fragrance work.

Science & Biotechnology

Separation from Aleppo pine rests on small characters: Brutia pine cones are usually sessile and arranged in whorls, its needles are on average longer and stiffer, and its bark fissures deeper. The Eldar variety from the dry eastern end of the range is a narrowly conical tree with shorter needles, and the Crimean form differs again, which is why the group has been split and rejoined several times by taxonomists.

Bark extractives of the Mediterranean pines carry the condensed tannins known as procyanidins, together with diterpene resin acids of the abietane and pimarane classes — abietic acid and pimaric acid among them — and the natural durability of the timber is largely the work of that fraction. Bark removed at sawmills is a research feedstock for tannin extraction and for adhesives.

Uses & Benefits

In Turkey and the Aegean, Brutia pine supports a scale insect, Marchalina hellenica, which feeds in the bark crevices and excretes a sugary honeydew. Bees collect that honeydew and make the dark, resinous pine honey of the eastern Mediterranean, and many pine forests there are managed as much for the honey as for the timber.

The wood is a workable softwood used for construction timber, pallets, crates, particleboard and pulp, and in rural districts it remains a primary fuelwood and charcoal source. The species coppices poorly, so stands are replaced by sowing rather than by cut-and-regrow.

Growing from Seed

Because the species survives drought, shallow limestone soil, salt wind and fire, it has been planted far beyond its native range for shelterbelts and land restoration. Provenance and progeny trials compare seed sources for survival on dry sites, growth form and drought response, which is how the material for coastal planting is chosen.

Brutia pine holds soil on eroding slopes and shelters crops and settlements from salt wind, so it is planted in belts above a shoreline, on terrace edges and on abandoned fields. It tolerates pruning and poor ground, and it grows fast enough on coastal sites to make a visible barrier within a few seasons.

Sow in late winter in a nursery bed of one part sieved loam, one part coarse sand and one part compost, covering the winged seed by a few millimetres. On a slope, sow into small pockets rather than broadcasting, and mulch each spot with a flat stone to hold moisture and reduce weed competition. Plant out at two to three metres along a shelterbelt, wider on a rehabilitation site.

Water only through the first summer, then let the roots find the subsoil; overwatering kills more young pines than drought. Keep a metre-wide weed-free collar around each seedling for the first two seasons, and where a site has been scalped bare, inoculate the planting spot with soil or litter from a healthy pine stand to introduce the ectomycorrhizal fungi that pines need to feed well.

Our Take

Brutia pine is the right tree in the wrong-looking place: a species for exposed coastal ground where more ornamental pines curl up and die. Plant it with other Mediterranean pines that cope with the same summer — the maritime pine, the tolerant black pine, or the high-altitude Bosnian pine for a colder ridge — and you can dress a whole dry hillside with a credible Mediterranean canopy.
