HABITAT TYPES AND PLANT COMMUNITIES : 
Whitethorn acacia is generally not a dominant plant but occurs as
scattered individuals in many plant communities.  Within Sonoran Desert
uplands, it attains its highest densities in washes [11].  It sometimes
codominates desert shrub types in the Chihuahuan Desert with
creosotebush (Larea tridentata) on gravelly loam [8].  Whitethorn acacia
is not listed as a dominant plant or habitat type indicator in any
published classifications.
