Climate

It has a continental climate characterized by warm, wet summers and dry, cold winters. Average annual precipitation (32.9 in, 835 mm) is sufficient to support woodland or savanna vegetation; consequently, drought, fire and grazing are important in maintaining this grassland.

Flora and fauna

The vegetation of Konza Prairie is dominated by native tallgrass which can reach over 2.5 metres in height in the most productive years. The prairie is dominated by plants adapted to the continental climate, mainly perennial grasses such as big bluestem ( ''Andropogon gerardii''), little bluestem ('' Andropogon scoparius''), Indiangrass (''

. The site was established to provide a natural laboratory for the study of ecological patterns and processes in native tallgrass prairie ecosystems. Key natural processes that regulate and sustain the tallgrass prairie are periodic fire, ungulate grazing, and a variable continental climate. Thus, these processes are the focus of much of the long-term research. Other research by the Kansas State University includes

Research has shown that reintroducing bison has long-term benefits as their presence makes the land more biodiverse and resilient to drought. The biological station provides educational opportunities for students from elementary school to post-graduate level. Members of the public are allowed onto portions of the Konza Prairie through three loop hiking trails (approximately 2.6, 4.5, and 6 miles). The Konza prairie was designated a UNESCO biosphere reserve in 1978. It was one of 17 reserves in the United States withdrawn from the programme in June 2017 by request of the U.S. government.
