Ponderosa pine is native to western North America.
Identification: Trees are 60-130' (18-39 m) tall, to a maximum of 260' (79 m). Trunks measure 31-47" (80-120 cm) in diameter (max 8' (2.5 m)). Twigs are orange-brown, rough, and springy. Needles occur in groups of 2-5, with three most common. Each needle is 2½-10" (7-25 cm) × ¹/₃₂" (1.5 mm), deep yellow-green, and slightly twisted. Cones are about 4½" (11 cm) long, oval to cylindrical when immature, maturing to be more egg-shaped.
