One-Seed Juniper

General: One-Seed Juniper (Juniperus monosperma) is a coniferous (cone-bearing) tree with tiny, scale-like leaves. The cones are round berries about 1/4-inch in diameter. This species is most easily recognized by the several branches that all arise from ground level.

In Nevada, One-Seed Juniper is common north of the mountain ranges around Las Vegas in such places as Lincoln and White Pine Counties. It is a common component of the Great Basin flats and montane vegetation in the Upper Sonoran (Pinyon-Juniper Woodland) life zone. This is the dominant species of juniper in east-central Nevada.
