HABITAT TYPES AND PLANT COMMUNITIES : 
Great Basin bristlecone pine usually occurs in almost pure stands and
reaches its greatest density on north-facing dolomitic slopes.  On
sandstone substrates limber pine (Pinus flexilis) is a codominant, but
on granitic substrates, Breat Basin bristlecone pine dominates [13].

Other species associated with the Great Basin bristlecone include white
fir (Abies concolor), Engelmann spruce (Picea engelmannii), and
ponderosa pine (Pinus ponderosa), and pinyon pine (P. edulis).  In
the mountains of central and southern Utah, bristlecones are associated
with quaking aspen (Populus tremuloides) and Rocky Mountain juniper
(Juniperus scopulorum) [1].
