What Aleppo Pine actually is#
Pinus halepensis is the pine you have seen on every dry Mediterranean hillside, from Spain and southern France across Italy, Greece and the Balkans to North Africa and the Levant. It tolerates drought and thin limestone soils better than any other pine in this catalogue, which is why it dominates degraded coastal landscapes and is planted heavily for erosion control.
That toughness in the field translates into an awkward timber. Growing under water stress produces irregular ring width, frequently wavy grain, and a lot of knots. It is a rougher and more variable wood than the northern pines, and it should be chosen for what it looks like rather than in spite of it.
What the numbers do and do not cover#
This species has partial data, and the gaps are worth explaining.
Density is listed at 540 kg per cubic metre, which sits between Maritime Pine at 500 and Scots Pine at 550. Modulus of rupture and shrinkage are also listed. All of these come from a single peer-reviewed study of Algerian material, cited on the species record.
There is no Janka hardness value and no elastic modulus. The general reference works do not publish a Janka figure for this species, and the study that measured stiffness did so under EN 310, a panel testing standard whose results are not comparable to the clear-wood values published for the other species here. Presenting 17.5 GPa next to Scots Pine at 10.08 GPa would imply a stiffness ranking that the test basis does not support, so the field is left empty rather than filled misleadingly.
There is also no durability rating, which matters practically: it means there is no sourced basis for recommending this wood outdoors.
The shrinkage figure is the interesting one#
The cited study measured volumetric shrinkage at around 8.3 percent, radial at 3.8 percent and tangential at 4.8 percent. That volumetric figure is the lowest in the entire KORENA catalogue, well below Maritime Pine at 14.4 percent.
More important than the headline number is the gap between radial and tangential. Cupping in a flatsawn board is driven by the difference between those two, and most species here run a ratio close to two to one. Aleppo Pine at 3.8 against 4.8 is far closer to one to one, which predicts unusually good behaviour across a wide flatsawn face.
Two caveats. The values come from Algerian material and this species varies widely across a very large range. And low shrinkage does not compensate for irregular grain, which causes its own distortion on drying regardless of how little the wood shrinks overall.
At the bench#
Expect tear-out. The wavy and irregular grain reverses direction within a single pass more often than in a northern pine, and a heavy cut will lift fibres wherever it does.
The working method that suits this wood is light cuts, sharp tooling, and a final surface produced with a card scraper or a high angle plane rather than by machining flat in one go. A helical cutterhead earns its cost here.
Resin loads blades and abrasives at roughly the level of Maritime Pine, which is to say constantly. Clean blades between operations and treat sandpaper as consumable. Wipe joint faces with acetone before glue-up, because resin on a jointed surface will compromise the bond.
Finishing#
Solvent wipe first, as with the other resinous Mediterranean pines: denatured alcohol or acetone, allowed to flash off, before any oil goes on. Skipping it produces patchy curing that only becomes visible after the work is finished.
Pigment stains blotch, so use a dye or leave it clear. Seal every knot with shellac before a painted finish. The orange tint in the heartwood deepens with light exposure.
Where Aleppo Pine is the right answer#
Rustic furniture, panelling, carcass work, shelving and decorative slabs where the irregular figure and knot pattern are wanted, and where the excellent flatsawn stability is useful.
It is the wrong answer for fine work, for anything requiring a calculated load path given the missing stiffness data, and for exterior use, where no durability rating exists to support the decision.
Sourcing and EUDR#
Not listed in the CITES Appendices. Supply is not constrained: the species is abundant across the Mediterranean and planted extensively on degraded land. Fire is the dominant pressure on these forests, and large burn events regularly push salvage volumes into regional markets. Aleppo Pine is fire adapted and regenerates readily, so salvage material is legitimate, but it should be identified rather than discovered. KORENA listings record the originating yard and region.
