Pinus flexilis occurs in limited numbers on northwest-facing slopes at an elevation of 6600 to 6800 ft (2002 to 2065 m) in the granitic region of the Black Hills of South Dakota. This is the eastern extension of a species more common at high elevations in western North America. Associated conifers are Pinus ponderosa and Picea glauca. The understory is dominated by Juniperus communis on lower, less steep slopes and by grasses, forbs, and cryptogams on the upper, steeper slopes. Soils are relatively deep, with developed profiles containing B2t horizons.
