Identifying Geographically Based Metapopulations for Development of Plant Materials
Indigenous to Rangeland Ecosystems of the Western USA.

Rangeland ecosystems account for about half of the earth’s land surface. They play an important role
in providing forage for livestock and wildlife, and they serve as critical watershed areas. Many of the
world’s rangelands have been degraded by overgrazing, marginal crop production, mineral and
energy extraction, recreation, and other human-caused disturbances. This degradation has led to
invasion by exotic weeds and subsequent increases in fire frequency. This, in combination with
uncertainties associated with global climatic change, has resulted in a critical need for plant materials
to restore and revegetate rangeland ecosystems. The assessment of genetic variation and its
phenotypic expression in important rangeland plant species (especially forbs) is critical in defining
population structures (genetically differentiated groups) that could be used in rangeland
restoration/revegetation efforts. We used common-garden studies and DNA-based analysis of genetic
variation to assess genetic diversity in three rangeland legume species indigenous to rangeland
ecosystems of the Great Basin Region of the western USA. Results of these studies are presented as
three case studies that describe data collection procedures, analysis, and interpretation used to
identify population structures in each species. These data formed the basis for combining plant
collections into geographically based metapopulations for the three legume species that are being
used to develop plant materials for commercial seed production and subsequent use on rangelands of
the Great Basin. Case studies include Astragalus filipes, Dalea ornata and D. searlsiae.
