HABITAT TYPES AND PLANT COMMUNITIES : 
New Mexico locust grows in pure stands or as an understory species [26].
New Mexico locust is an understory dominant or codominant with Gambel
oak (Quercus gambelii) under spruce-fir (Picea engelmannii-Abies
lasiocarpa), white fir (A. concolor), and mixed-conifer forests
[1,16,20,24,37,40].  It is a minor component in most riparian forest and
scrubland community types within its range, and in one chaparral
association (Arizona oak-yellowleaf silktassel-Emory oak [Q.
arizonica-Garrya flavescens-Q. emoryi]) [8,51,52].
