Rank Reasons
Southwestern Oregon to northern Baja California (Mexico), in scattered localities. In Mexico, it is quite rare in Mexico, where it is one of three pine species native to Baja California. Small populations near Ensenada should be protected and could serve as a source of seed for test plantings in the state of Baja California Norte. In the U.S. it occurs primarily in SW Oregon, with small populations in California.
Ecology & Habitat

Habitat

On Sierra Juárez it grows at 250-1200 m altitude, rocky, gravelly-sandy soil, with winter anual rainfall of 600 mm aprox. Hot temperatures in the summer and snow and frezzing in the winter.
