These results were found on deep, fertile soils on lower slopes in areas experimentally burned on Konza Prairie Research Natural Area in Geary County, Kansas. Height, density, and weight of flower stems of big bluestem were highly significantly greater as the length of interval increased. Indian grass and little bluestem showed some of the same tendency, but primarily showed marked reductions in the 6-year interval area, resulting in an increased dominance by big bluestem</p>10aflowering10aprairie10atallgrass1 aHulbert, L.C.1 aWilson, J.K.1 aKucera, C.L.  uhttp://129.130.186.12/content/fire-interval-effects-flowering-grasses-kansas-bluestem-prairie
