Ranches key to conservation in rocky mountains

s that are typical of the local native shrub/grassland habitat, such as green-tailed towhees and vesper sparrows. In contrast, rural developments had higher densities of nest predators, such as the black-billed magpie, and of birds that are usually uncommon to the area, such as Bullock's oriole, a tree-nester that is presumably attracted by the landscaping trees.

Moreover, ranches had more native plant species and fewer non-native plant species than rural developments and reserves. Altogether the ranches had only half as many non-native plant species as the rural developments, and only two-thirds as many as the reserves (11 vs. 23 and 17, respectively). In addition, the coverage of cheatgrass, the most common non-native plant, was lower on ranches than on rural developments or reserves (14%, 18% and 22%, respectively).

"Ranches can be more effective than reserves at maintaining native biotic communities," say Maestas and his colleagues. Reserves may be inadequate because most are in harsher environments with higher elevations and poorer soil. Moreover, the reserves studied have extensive trail systems that could facilitate the spread of non-native plants.
