Economic view

Corsican and Calabrian pines are the third most frequently-used species for reforestation in France.  They have a number of qualities for ecosystems and for industry.

They are appreciated for plantation in natural zones as they provide a habitat for certain bird species. This is why the Corsican pine is described as a species with heritage value.

The acquisition of a Corsican pine wood can therefore be a worthwhile investment: evidently for environmental reasons, but also because its timber has some remarkable qualities, appreciated in the sector.

It is used for carpentry, veneer, wood panels, cabinetwork and for pallets, and its essential oil is used as a natural antiseptic.

Finally, Corsican pine grows rapidly and produces quality wood.
