This indicator provides a surrogate measure of intensive human uses of rangeland through the use of road density measures and housing densities. Many intensive uses of rangeland are often not represented in land cover maps because of their small individual spatial extents. Examples of these types of land uses of rangeland include low-density rural housing developments, power lines, off-road vehicle (ORV) uses, mines, and oil and gas wells, along with their associated transportation infrastructure. The potential ecological impacts of intensive human uses of rangeland include loss and fragmentation of rangeland, rangeland plant communities, and open space, reduced primary and secondary productivity and biodiversity, increased soil disturbance and susceptibility to wind and water erosion, disruption of material flows and ecological processes in the landscape (e.g., groundwater flow), fire spread, and enhanced opportunities for successful establishment of invasive plants and animals.
