| Livestock grazing, which continued from the 1880's until 1979, devastated some cactus forests. Seedlings were killed outright by trampling or were tramping or were unable to find suitable places to grow because the ground had been compacted and nurse plants killed. Today, with grazing eliminated, recovery of the saguaro is underway in several areas. Thousands of young saguaros have taken hold, and they are thriving. | |
