Ponderosa pine
Pinus ponderosa
Ponderosa pine occurs on extremely dry to well-drained, relatively deep, moist soils. It grows in pure, open, park-like groups at lower elevations. At higher elevations it grows with Interior Douglas-fir. A long, deep root allows it to access deeper, moister soil and also makes it quite wind-firm. Lifespan can reach 400 to 500 years.
