	abstract = {<p>Between 1915 and 1932, 104 permanent 1x1-m quadrats were established on grasslands of the Jornada Experimental Range in southern New Mexico.\&nbsp; Primary- and secondary-dominant species were determined from the first quadrat records and each quadrat was reevaluated in 1981 to determine current dominants.\&nbsp; The first records showed that 13 species of perennial grasses occupied all primary- and secondary-dominant positions on all quadrats.\&nbsp; In 1981, there were 12 perennial grass species as primary- or secondary-dominance.\&nbsp; Six shrub species occurred as primary- or secondary-dominance on 47\% of the quadrat sites in 1981.\&nbsp; Dominance-classes, i.e., single-species dominance or two-species dominant combinations, increased from 24 to 43.\&nbsp; Thus, vegetation on this range has become more diverse and this diversity must be considered in grazing management.\&nbsp;</p>
