Distribution and Ecology

Morocco & Algeria: the Atlas and Riff Mountains, 1000-2000 m, where it forms monspecific stands (Vidakovic 1991). Hardy to Zone 7 (cold hardiness limit between -17.7°C and -12.2°C) (Bannister and Neuner 2001).

Big tree

A specimen 382 cm dbh and 30 m tall is recorded in Parco Castello, Piemonte, Montalenghe, TO, Italy. Another, 181 cm dbh and 40 m tall, grows in parco Sella, Piemonte, Mosso Santa Mar, VC, Italy (Alberi Monumentali d'Italia, a listing of big trees in Italy).

Oldest

Dendrochronology

Numerous collections by Charles Stockton, working in Morocco ca. 1984-1989. The climate-ring width relationship is explored by Till (1987). Further work can be located at the Bibliography of Dendrochronology.

Ethnobotany

"It is a light-demanding tree which succeeds on basic soils, and it is quite hardy. A fast growing species, it is cultivated for ornamental purposes in parks and avenues, and may be used for afforestation of the Mediterranean and sub-Mediterranean barren lands.

"Wood is durable and used in building and for furniture" (Vidakovic 1991).
