Galleta is widespread throughout
southern California to the desert mountains of Nevada,
Arizona, New Mexico,
Utah, Colorado, Wyoming and western Texas [40,46,47]. Galleta is also found in the panhandle
of Oklahoma and extreme southwest Kansas [46]. The PLANTS database
shows the distribution of galleta.
In the Southwest galleta is a member of pinyon-juniper (Pinus-Juniperus) and ponderosa pine (P. ponderosa)
habitat types [89,94] and an important component of plains grasslands [12]. Galleta is also a member of northern desert-shrub
communities of California, Nevada, Utah and Colorado [15].
Galleta is an important understory component in northern regions of the southwestern pinyon-juniper
ecosystem [66,72], and in the conifer woodland-grassland transition zones [11].
Galleta is a member of tallgrass communities along the New Mexico-Colorado
border in association with little bluestem (Schizachyrium scoparium), western wheatgrass (Pascopyrum smithii), needle-and-thread (Hesperostipa comata), purple threeawn (Aristida purpurea),
and sand dropseed (Sporobolus cryptandrus) [12].
In Arizona galleta occurs in pinyon-juniper, shortgrass, and
sagebrush plant communities [75]. In Utah, galleta occurs in salt desert shrub, creosote bush (Larrea tridentata),
desert shrub, sagebrush, pinyon-juniper [92], and blackbrush (Coleogyne ramosissima) communities [88]. In the central portion of the Great Basin (Nevada), galleta forms a habitat type with big sagebrush (Artemisia tridentata) [84].
Common plant associates:
Grasses: black grama (Bouteloua eriopoda) [22,35], blue grama
(Bouteloua gracilis) [8,22,75], little bluestem, needle-and-thread [12],
Indian ricegrass (Achnatherum hymenoides) [7], desert needlegrass (A
speciosum) [85], bottlebrush squirreltail (Elymus elymoides), Sandberg bluegrass (Poa secunda) [8], alkali sacaton (Sporobolus airoides), sand dropseed [8,30,31], gyp dropseed (S. nealleyi), spike dropseed (S. contractus) [31], Fendler threeawn (Aristida purpurea var. fendleriana) [35], and
western wheatgrass [75],
