6 Answer Key Western Juniper Bluebunch wheatgrass Cheatgrass Big Sagebrush Medusahead 1. a 2. d 3. b 4. c 5. d 6. c 7. b 8. c 9. b 10. d Rangelands are any landscape in which grasses are a dominate plant species. They can be open rangelands and grasslands which have no shrubs or trees, to ponderosa or juniper forest with grasses in the understory. Grasslands cover vast areas of North America. The sagebrush steppe ecosystem main characteristics are an arid land with generally high elevation. The dominant plant species are shrubs and perennial grasses, such as sagebrush and bunchgrasses. Judge student answers. These ecosystems are being taken over by invasive annual grasses and other weed species. These invasive plants generally outcompete native perennial grasses and thus decrease biodiversity. The invasive are less forgeable to grazing animals from livestock to deer and antelope.
