Dixon Vernal Pools represents the best example of the valley needlegrass grassland in the Great Central valley of the South Pacific Border biophysiographic province. There are only three valley needlegrass grassland sites remaining today. The site contains extensive stands of perennial needlegrass in a mosaic with claypan vernal pools, another critically rare natural community. The rolling hummocky topography results in a complex patchwork of grasses and native wildflowers.
