The Hispaniola pine is endemic to the Dominican Republic and Haiti and currently listed as an endangered species.

Gregg's pine is nearly threatened and can be found scattered across the Sierra Madre Oriental in Mexico. It usually associated with other pine species.

While the main extent of this species range is along the Sierra Madre Occidental into southern Mexico, it can also be found growing in SE Arizona and SW New Mexico.

Not to be confused with another conifer, the Douglas fir,  Pseudotsuga menziesii - the Douglas pine is exclusively found in Mexico. 

This species thrives in areas of extremely high elevations, between 8,000 and 13,000 feet.

These pines are completely dependent on four bird species to disseminate their seeds: the Mexican jay (Aphelocoma ultramarina), pinon jay (Gymnorhinus cyanocephalus), Stellar's jay (Cyanocitta stelleri), and Clark's nutcracker (Nucifraga columbiana).

The wood of the pitch pine was used for decorative carvings as well as canoes by the Cherokee.
