Heart Mountain Wyoming big sagebrush steppe. Bird's-foot sagebrush small leaves each with three narrow leaflets, which are arranged like the toes in a bird's foot.
Wyoming big sagebrush was once common in the upland areas of the Crazy D Ranch, as inferred by the abundance of burned sagebrush skeletons in this area, and by the remaining decimated and depauperate populations and individuals. This site lies in the upland pass area in the open arid rangeland of the Crazy D Ranch, southwest of Melville, Sweetgrass County, Montana.
The last photo was taken at the same site during 2023 to illustrate one of the larger skeletons observed in this area of Wyoming big sagebrush.
Basin wildrye at the Cherry River Fishing Access, Bozeman, Montana, appears to limit the growth of smooth brome (Bromus inermis) at the periphery of each bunch. Smooth brome is uniformly with a short stature adjacent to each wildrye bunch and with a distinctly taller stature just a foot away from each wildrye bunch.
Russian or Bozoisky wildrye is bunchgrass with relatively short basal leaf bunches. It is common on converted or highly disturbed open dry rangeland in this area of Sweet Grass County north of Big Timber. This site lies near a calving shed on the Crazy D Ranch, southeast of Melville, Sweet Grass County, Montana. From USDA NRCS plant materials information: 'Bozoisky-Select' Russian wildrye was selected by the USDA Agricultural Research Service (ARS), Logan, Utah, for improved seedling vigor and increased forage.
Little sagebrush replaces black sagebrush in this region at upper elevations, including here on HD Summit (elevation 6280 feet), north of Wells, Elko County, Nevada. Inflorescence spikes bearing tridentate leaves and bracts are in part diagnostic of little sagebrush.
