The often steep and rugged lower slopes of the mountains are dominated by cacti, agaves, yuccas, and thorn-bearing shrubs. |
In summer months they eat cacti, sagebrush, mesquite, alfalfa, clover, other grasses, and herbaceous vegetation. |
In addition, few cacti should show extensive surface injuries if saguaros live for long time periods. |
Ms Lloyd said cacti could injure livestock and working dogs and contaminate wool. |
The bark on saguaros and many other species of columnar cacti is usually a dark brown to black color. |
As we began descending from mountains into the desert, I saw agaves, cacti, and ocotillo thriving on the dry, rugged slopes. |
