HABITAT TYPES AND PLANT COMMUNITIES : 
In the Southwest junipers (Juniperus spp.) are associated with oaks
(Quercus spp.) and true pinyon (Pinus edulis).  Junipers increase in
dominance over oaks and pinyons on dry sites [14].  Redberry juniper is
common in alligator juniper (J. deppeana)-pinyon woodlands and savannas,
and in areas where its range overlaps with Utah juniper (J.
osteosperma), oneseed juniper (J. monosperma), and Rocky Mountain
juniper (J. scopulorum) [8].  It occurs in evergreen oak woodlands with
Emory oak (Q. emoryi) and Mexican blue oak (Q. oblongifolia) [11].
Redberry juniper is also found in Arizona chaparral woodlands with shrub
live oak (Q. turbinella) and Arizona rosewood (Vauquelinia californica)
[20].  It occurs as scattered individuals in grama (Bouteloua spp.)
grasslands, along with scattered velvet mesquite (Prosopis velutina),
Mexican blue oak, and alligator juniper [14].
