Native grasslands adjacent to crested wheatgrass fields were mixed-grass prairie dominated by Agropyron smithii, Agropyron dasystachyum, Stipa comata, Poo secunda and Bouteloua gracilis
. Wyoming big sagebrush (Artemisia tridentata ssp.
All roadsides contained dense grasses of various species and heights, including Johnsongrass (Sorghum halepense), blue grama (Bouteloua gracilis
), little bluestem (Schizachyrium scoparium), and sprangletop (Leptochloa fusca), as well as some forbs including burningbush (Bassia scoparia).
Structure--For microphyllous scrub and areas with livestock, we registered a high dominance of creosote bush (Larrea tridentata; 16.6%), and blue grama (Bouteloua gracilis
Common grasses included western wheatgrass (Pascopyrum smithii), blue grama (Bouteloua gracilis
), needle and thread (Stipa comata), prairie junegrass (Koeleria pyramidata) and threadleaf sedge (Carex filifolia).
santaclarensis, bosques mixtos de encino, bosque espinoso, pastizal de Bouteloua gracilis
y matorral desertico; Rzedowski (1978) ubica cuatro tipos de vegetacion para el estado: matorral xerofilo, pastizal, bosque de coniferas y encinos y bosque tropical caducifolio.
(1980) showed Bouteloua gracilis
distributed photosyntetically fixed [C.sup.14] toward the roots, promoting fast adventitious root growth three weeks after the simulation of root herbivory.
Cactus is often found growing amongst prairie grasses such as Spear Grass (Stipa comata Trim & Rupr.) and Blue Grama (Bouteloua gracilis
El C17 se constituyo por 13 sitios y por 6 especies: Prosopis glandulosa, Aloysia gratissima, Acacia constricta, Bouteloua gracilis
, Larrea tridentata y Acacia greggii.
(19 % cover) and Carex filifolia (15 % cover) were the dominant graminoids at the site, while Yucca glauca (1% cover) and Artemisia frigida (1% cover) were the most frequent forbs.
Endowed with sandy soils derived from the nearby North Canadian River, the range is host to native plants--mostly sand sage (Artemisia filifolia) and grasses such as sand bluestem (Andropogon hallii), little bluestem (Schizachyrium scoparium), sand dropseed (Sporobolus cryptandrus), and blue grama (Bouteloua gracilis
This research was conducted to (1) quantify C[O.sub.2] respired by soil microbes inhabiting the soil beneath Artemisia tridentata, Bouteloua gracilis
, and bare ground in grazed and ungrazed rangeland, which is an indirect measure of microbial biomass, (2) to determine percent carbon, percent nitrogen, and organic matter content of the soil, and (3) determine the correlation between 1 and 2.
