Juniperus osteosperma (Utah juniper; syn. J. utahensis) is a shrub or small tree native to the southwestern United States. Description The plant reaches , rarely to 9 m, tall. The shoots are fairly thick compared to most junipers, in diameter. The leaves are arranged in opposite decussate pairs or whorls of three; the adult leaves are scale-like, 1–2 mm long (to 5 mm on lead shoots) and 1–1.5 mm broad. The juvenile leaves (on young seedlings only) are needle-like, long. The cones are berry-like, in diameter, blue-brown with a whitish waxy bloom, and contain a single seed (rarely two); they mature in about 18 months and are eaten by birds and small mammals. The male cones are 2–4 mm long, and shed their pollen in early spring. It is largely monoecious with both sexes on the same plant, but around 10% of plants are dioecious, producing cones of only one sex. The plants frequently bear numerous galls caused by the juniper tip midge Oligotrophus betheli (Bibionomorpha: Cecidomyiidae); these are conspicuous pale violet-purple, produced in clusters of 5–20 together, each gall in diameter, with dense modified spreading scale-leaves long and 2–3 mm broad at the base. Distribution and habitat The species is native to the southwestern United States, in Utah, Nevada, Arizona, western New Mexico, western Colorado, Wyoming, southern Montana, southern Idaho and eastern California. It grows at moderate altitudes of , on dry soils, often together with Pinus monophylla. Ecology Seeds are dispersed by a variety of mammals and birds. Mammals include jackrabbits (mostly the black-tailed jackrabbit Lepus californicus spp.) rodents and to a lesser extent by coyotes (Canis latrans). Most notable among the birds that disperse juniper berries is the Townsend's solitaire (Myadestes townsendi). Uses Native Americans such as the Havasupai used the bark for a variety of purposes, including beds, and ate the cones both fresh and in cakes. The Havasupai used the gum to make a protective covering over wounds. Additionally, the Yavapai gave their women a tea made from the leaves to calm their contractions after giving birth, and fumigated them with smoke from the leaves placed over hot coals. The Navajo sweep their tracks with boughs from the trees so death will not follow them. A small quantity of ripe berries can be eaten as an emergency food or as a sage-like seasoning for meat. The dried berries can be roasted and ground into a
