Pinus leiophylla, commonly known as Chihuahua pine, smooth-leaf pine, and yellow pine
Habitat and ecology
This species often grows in mixed in stands with several other pines and/or junipers, in Arizona most often with Apache Pine and Alligator Juniper, but also grows in pure stands. Its habitat is prone to wildfire, and the species shows some adaptations unusual among pines to cope with this; if the crown is destroyed by fire, the trunk, protected by its thick bark, will send out new shoots to re-grow a new crown. The only other pines to do this are Pitch Pine (P. rigida) and Canary Island Pine (P. canariensis). As none of these are species particularly closely related to each other, the adaptation has probably arisen independently in each, an example of convergent evolution.
Cultivation and uses
The wood of the Pinus leiophylla is hard, dense and strong. It is used for construction, firewood, and railroad ties. In South Africa and Queensland, Australia there are big extensions of this tree planted. It is planted commercially in Kenya, Malawi, Zimbabwe, Zambia at high altitudes.
