DISTRIBUTION AND OCCURRENCE
SPECIES: Sarcobatus vermiculatus | Black Greasewood 



GENERAL DISTRIBUTION : 
Black greasewood is widely distributed from the northern desert ranges
of Canada to Mexico [39].  It occurs in Washington and Oregon east of
the Cascades to southeastern California east of the Sierras [21].  Black
greasewood extends eastward to the Dakotas, Wyoming, and Colorado, and
southward into northwestern New Mexico and Texas [21].  It is a dominant
species throughout much of the Great Basin [50].

HABITAT TYPES AND PLANT COMMUNITIES : 
Black greasewood is an indicator of nonclimatic (physiographic, edaphic,
or biotic) climax in a number of saltbush (Atriplex spp.), sagebrush
(Artemisia spp.), and sagebrush-grassland communities.  It occurs as a
codominant with western wheatgrass (Pascopyrum smithii), basin wildrye
(Leymus cinereus), bottlebrush squirreltail (Elymus elymoides),
saltgrass (Distichlis spicata), ricegrass (Oryzopsis spp.), big
sagebrush (Artemisia tridentata), budsage (A. spinescens), rubber
rabbitbrush (Chrysothamnus nauseosus), and shadscale (Atriplex
confertifolia).  Published classifications listing black greasewood as a
plant community dominant or indicator are:

Plant associates:  Other plants commonly occurring with black greasewood
include black sagebrush (A. nova), Nevada ephedra (Ephedra nevadensis),
Nuttall's saltbush (Atriplex nuttallii), fourwing saltbush (A.
canescens), green rabbitbrush (C. visicidiflorus), Russian-thistle
(Salsola kali), spiny hopsage (Grayia spinosa), alkali sacton
(Sporobolus airoides), cheatgrass (Bromus tectorum), and pickleweed
(Allenrolfea occidentalis) [13,29].  Understory vegetation is often
sparse in black greasewood communities.  Bare soil may represent a
fairly large percentage of the cover and plants are often widely spaced.
In a western Utah study, greasewood averaged 13 individuals per square
rod [13].
