HABITAT TYPES AND PLANT COMMUNITIES : 
Torrey wolfberry is characteristic of mesquite (Prosopis
glandulosa)-fourwing saltbush (Atriplex canescens) vegetation in the
Chihuahuan Desert on deep, fine alluvium near shallow arroyos and on
alluvial fans and bajadas.  Other associated species include
creosotebush (Larrea tridentata), tarbush (Flourensia cernua), prickly
pear and cholla (Opuntia spp.), and agave (Agave scabra).  Torrey
wolfberry is also found in alkali sacaton (Sporobolus airoides)
grasslands in deep, calcareous alluvial deposits near arroyos and in
intermontane habitats along the margins of mesquite communities [8].
