Juniper Age and Distribution on an Isolated Butte in Garza County, Texas

The density and age distribution of redberry juniper on an isolated butte were determined to learn the possible origin and direction of spread of the juniper. The northern half of butte supported the denser stands. The densest stand was in the northwest corner of the top but the oldest trees were found on northwest mid-slopes indicating the northwestern part of butte as center of distribution and possible source of younger junipers found downslope.
