Description

Pinus canariensis is a large evergreen tree, growing to 30–40 metres (98–131 feet) tall and 100–120 centimetres (39–47 inches) diameter at breast height, exceptionally up to 60 m (200 ft) tall and 265 cm (104 in) diameter. The green to yellow-green leaves are needle-like, in bundles of three, 20–30 cm (7.9–11.8 in) long, with finely toothed margins and often drooping. A characteristic of the species is the occurrence of glaucous (bluish-green) epicormic shoots growing from the lower trunk, but in its natural area this only occurs as a consequence of fire or other damage. The cones are 10–18 cm (3.9–7.1 in) long, 5 cm (2.0 in) wide, glossy chestnut-brown in colour and frequently remaining closed for several years (serotinous cones). Its closest relatives are the chir pine (P. roxburghii) from the Himalayas, the Mediterranean pines P. pinea, P. halepensis, P. pinaster and P. brutia from the eastern Mediterranean.

Taxonomy

Pinus canariensis was first described in 1825 by Augustin Pyramus de Candolle, who attributed the name to Christen Smith. It has been placed in subsection Pinaster of subgenus Pinus, section Pinus. The other species in the subsection are mainly Mediterranean in distribution, with one species (P. roxburghii) from the Himalayas.

Distribution and habitat

The species is native and endemic to the outer Canary Islands (Gran Canaria, Tenerife, El Hierro and La Palma). It is a subtropical pine and does not tolerate low temperatures or hard frost, surviving temperatures down to about −6 to −10 °C (21 to 14 °F). Within its natural area, it grows under extremely variable rainfall regimes, from less than 300 millimetres (12 in) to several thousands, mostly due to differences in mist-capturing by the foliage. Under warm conditions, this is one of the most drought-tolerant pines, living even with less than 200 mm (7.9 in) of rainfall per year.

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.

Fossil record

Fossils of Pinus canariensis have been described from the fossil flora of Kızılcahamam district in Turkey which is of early Pliocene age. Fossil cones including seeds of Pinus canariensis are known from the late Miocene of Abkhazia, from the Vienna Basin and the Canary Islands. Numerous cone casts including seeds of Pinus canariensis from the early Pleistocene, were recovered on Kallithea, Rhodes.

Ecology

This pine is one of the most fire-resistant conifers in the world, due to several beneficial adaptations.

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.

The aromatic wood, especially the heartwood, is among the finest of pine woods, being hard, strong and durable.

In mainland Spain, South Africa, Sicily and Australia, it has become a naturalized species from original landscape uses.

Pinus canariensis is a popular ornamental tree in warmer climates, such as in private gardens, public landscapes, and as street trees in California.
