Other "Aegilops" are weeds of rangeland and wildland habitat. These techniques must be linked with good grazing practices in rangeland areas. "Artemisia frigida" is also used in landscaping and for erosion control and revegetation of rangeland. Today, land use is a mixture of rangeland, pastures, and farmland. Overgrowth of the plant is sometimes an indicator of overgrazing on rangeland. Land use through the region atop the Edwards aquifer varies between rangeland, agricultural and residential/urban. Downstream it flows through "Bob Creek Wildland Park" and "Black Creek Heritage Rangeland". Enterprises where livestock are raised on rangeland are called "ranches". It is both an agronomic and rangeland weed. There are also limited amounts of chaparral, brush and grass/rangeland within the basin. In the 1870s, cattlemen began to discover their potential as rangeland for Longhorn cattle. Gideon Kressel has proposed a brand of pastoralism that preserves open spaces for rangeland herding. Rangeland assessments show that the heritability of aggressiveness in cattle is around 0.36. Holistic management has been likened to "a permaculture approach to rangeland management". The American Indians used fire to maintain such areas as rangeland.
