HABITAT TYPES AND PLANT COMMUNITIES : 
White burrobrush is commonly found in creosotebush (Larrea tridentata),
shadscale (Atriplex confertifolia), and saltbush (Atriplex spp.) scrub,
Joshua tree (Yucca brevifolia) woodlands, and pinyon-juniper woodlands
[27,36,30].  Johnson [15] describes a white burrobrush community type in
the desert washes of the Mojave Desert characterized by white
burrobrush, desert saltbush (Atriplex polycarpa), desert rabbitbrush
(Chrysothamnus paniculatus), and catclaw acacia (Acacia greggii).  Hanley
and Brady [14] describe a paloverde (Cercidium spp.)-white burrobrush
community type in Sonoran Desert washes.

In addition to the above mentioned species, white burrobrush is commonly
associated with smoke tree (Dalea spinosa), white bursage (Ambrosia
dumosa), brittle bush (Encelia farinosa), jojoba (Simmondsia chinensis),
sweetbush (Bebbia juncea), desert agave (Agave deserti), ocotillo
(Fouquieria splendens), range ratany (Kramerica parvifolia), teddybear
cholla (Opuntia bigelovii), desert willow (Chilopsis linearis), and
rubber rabbitbrush (Chrysothamnus nauseosus) [42,44,45].

wash communities is listed below:
