Growing Regions

Ashe juniper has a limited range in southwestern North America. It occurs in disjunct populations in southwestern Missouri and Arkansas, in the Arbuckle Mountains of southern Oklahoma, and in Coahuila, Mexico. The main population occurs in west-central Texas, largely on the Edwards Plateau [20,28,41].

     

General Information

The accepted scientific name for Ashe juniper is Juniperus ashei Buchholz. Ashe juniper is thought to hybridize with redberry juniper (J. pinchotii) [19,30]. Adams and Kistler [3] summarized a number of studies that investigated the report that Ashe juniper hybridizes with eastern redcedar (J. virginiana) [17,18]. They concluded that there was no evidence of gene flow between the two species, even though their ranges overlap, and morphological intermediates exist. There are no recognized subspecies, forms, or varieties of Ashe juniper.

Ashe juniper forms dense to open communities with oaks (Quercus spp.),
including live oak (Q. virginiana) and Mohr oak (Q. mohriana), Texas
persimmon (Diospyros texana), and mesquite (Prosopis spp.).  These
communities have invaded many acres of adjacent little bluestem
(Schizachyrium scoparium) grasslands as a result of overgrazing and fire
suppression [42].

Publications which list Ashe juniper as a dominant or codominant
species include:

Utilization of grass- and shrublands of the southwestern United States [21].  
A comparison of some woody upland and riparian plant communities
  of the southern Edwards Plateau [46].
An ecological comparison of upland deciduous and evergreen forests of
  central Texas [45].  
North American shrublands [31].
