The native range has been somewhat reduced due to over-cutting so that only the islands of Tenerife, La Palma and Gran Canaria still have large forests. Really big trees are still rare due to past over-cutting. It is the tallest tree in the Canary Islands.

Uses
The tree's extremely long needles make a significant contribution to the islands' water supply, trapping large amounts of condensation from the moist air coming off the Atlantic with the prevailing north eastern wind (locally called "alisios"). The condensation then drops to the ground and is quickly absorbed by the soil, eventually percolating down to the underground aquifers.
