DISTRIBUTION AND OCCURRENCE
SPECIES: Atriplex canescens | Fourwing Saltbush 



GENERAL DISTRIBUTION : 
Fourwing saltbush is widely distributed throughout the western United
States from the Pacific Coast Ranges to the Great Plains [25].  It
extends from northern Mexico to southern Canada [36].

Diploids occur most commonly in Mexico, New Mexico, and southern
Arizona, with an isolated population in the Little Sahara Sand Dunes of
central Utah [53].  Tetraploids are widely distributed and hexaploids
reach greatest abundance in Nevada [53].  Decaploids and 12ploids grow
in southern California, Baja California, and northwestern Mexico [53].

HABITAT TYPES AND PLANT COMMUNITIES : 
Fourwing saltbush occurs as an understory species in many Great Basin
conifer forests, pinyon (Pinus spp.)-juniper (Juniperus spp.) woodlands,
northern and southern desert shrublands, Mohave and Sonoran desert
scrub, and salt desert scrub communities [29,56,62].  It is seldom found
in pure stands, but grows as a dominant or codominant species in a
number of saltbush-grassland communities.  Common codominants or
associates include blue grama (Bouteloua gracilis), black grama (B.
eriopoda), galleta (Hilaria jamesii), alkali sacaton (Sporobolus
airoides) and other dropseeds (Sporobolus spp.), bottlebrush
squirreltail (Elymus elymoides), western wheatgrass (Pascopyrum
smithii), Indian ricegrass (Oryzopsis hymenoides), rubber rabbitbrush
(Chrysothamnus nauseosus), black greasewood (Sarcobatus vermiculatus),
black sagebrush (Artemisia nova), and broom snakeweed (Gutierrezia
sarothrae) [14,59,62].  Fourwing saltbush is listed as a dominant or
indicator species in the following publications:

Phyto-edaphic communities of the Upper Rio Puerco Watershed, New Mexico [10]

  Wyoming, South Dakota, Nebraska, Colorado, and Kansas [17]
