There is but little natural vegetation to be seen - ragged yucca trees, many species of agave and cactus, scrubby mesquite bushes, sage bushes and occasional clumps of coarse grasses.

The tree yucca often attains a height of 20 to 25 ft., and a diameter of 1.5 ft.
New Mexico has such a great range of elevations that all four of the zones of vegetation into which the South-West has been divided according to altitude are found within its limits; namely, the zone of cactus, yucca and agave (3000-3500 ft.), where grass is scanty; the zone of greasewood and sage-brush (3500-4900 ft.), where there is little grass, and the cactus species are less numerous; the zone of the cedar (4900-6800 ft.); and the zone of the pine and fir (6800 - 10,800 ft.), in which grass is more abundant.
