throughout the Great Plains.  It is distributed from Canada to Mexico,
and from California eastward to the Atlantic Coast [24].  Blue grama has
been introduced in many locations in the eastern United States [24].

HABITAT TYPES AND PLANT COMMUNITIES : 
Blue grama is a climax indicator in many grassland, sagebrush, desert
shrub, pinyon-juniper, and ponderosa pine communities and habitat types.
It is associated with a variety of species including one-seed juniper
(Juniperus monosperma), big sagebrush (Artemisia tridentata), broom
snakeweed (Gutierrezia sarothrae), galleta (Hilaria jamesii), dropseed
(Sporobolus spp.), western wheatgrass (Pascopyrum smithii), bluebunch
wheatgrass (Pseudoroegneria spicata), buffalo grass (Buchloe
dactyloides), needle-and-thread (Stipa comata), sand bluestem
(Andropogon gerardii var. paucipilus), and big bluestem (Andropogon
gerardi var. gerardii).
