	abstract = {<p>Vegetation cover and buried seeds were studied on three upland sites burned at different intervals (unburned, 4-year burn, and annual burn) in tallgrass prairie in northeastern Kansas. Vegetation of all sites (89 species total) was dominated by Andropogon gerardii (76 to 81\% cover). Schizachyrium scoparium and Sorghastrum nutans cover was higher, whereas Poa pratensis and Sporobolus hererolepis cover was lower on more frequently than on less frequently burned sites. A total of 735 seedlings comprising 28 species were recorded in soil samples from the three treatments. Seed density was variable within and between treatments but was generally highest in unburned treatment and lowest in annually burned prairie. Many Sporobolus cryptandrus were recorded in each treatment. The number of forb seedlings was not significantly different between treatments and was dominated by Erigeron strigosus and Oxalis stricta. Many species that germinated from buried seeds were not recorded as vegetation on the site, and much of the vegetation was not represented as seedlings. The scarcity of viable buried seeds of the dominant tallgrasses and forbs suggest that they are highly dependent on vegetative propagation</p>},
