Plains Grassland




The Plains Grassland in Arizona is an extension of the Great Plains that extend throughout much of central North America. The plains are dominated by grasses and can be divided into subregions based upon the height of the dominant grass species. Our subset of the Plains Grassland is dominated by little bluestem, (Schizachyrium scoparium), big bluestem, (Andropogon gerardii), buffalograss (Buchloe dactyloides), and sideoats grama grass (Bouteloua curtipendula). Shrubs are usually low growing and often associated with rock ledges. Some common shrubs are little sagebrush (Artemisia arbuscula) and whipple's cholla (Cylindropuntia whipplei). In overgrazed areas, snakeweed (Gutierrezia sarothrae) and russian thistle (Salsoa tragus), are common.
