Sierra Aconchi
The Sierra Aconchi is remote and little visited range that reaches elevations that support very small, limited stands of pure pine. Most of the range is oak woodland, with some pine/oak at higher elevations. Interesting species to note are apache pine (Pinus engelmannii), Chihuahua pine (Pinus leiophylla var. chihuahuana), Arizona pine (Pinus arizonica), Quercus coccolobifolia, and Texas madrone (Arbutus xalapensis).
