Comments: In the southwestern United States populations of Oneseed Junipers appear to be determined through a combination of variables which include soils, temperatures, rainfall and topography. Elevation ranges, and location of specimens vary across the range of the species from 3,000 to 7,000 in Arizona, 4,000 to 7,600 in Colorado and 5,000 to 7,500 in New Mexico; thus, together determining the presence or absence of the plants.
