The reference state and the reference plant community (Historic Climax Plant Community) has been determined by study of relict areas or areas protected from excessive disturbances. Trends in plant communities going from heavily grazed areas to lightly grazed areas, seasonal use pastures and historical accounts have also been used. This reference state is characterized as a native mid and short grassland with scattered shrubs and trees. The dominant herbaceous cover is warm season grasses such as black grama, blue grama and galleta. Dominant woody species is a mix of large and low growing shrubs along with scattered trees.
