Seeds are dispersed by mammals and birds.
Rabbits can carry seed up to one mile.
Germination of Pinchot juniper seeds declines with a decrease in moisture availability. Pinchot juniper occurs on open flats, on dry hillsides, in canyons, caprock regions, and talus slopes. Following top removal, Pinchot juniper sprouts are only slightly affected by competition from herbaceous species in terms of reproductive succcess, growth rate, and survival. The maintenance of continuous Pinchot juniper stands depends on at least 2 consecutive years of cooler and wetter than average weather occurring during the lifespan of the trees in a stand.
