OSU Marvin Klemme Research Range Station

The Marvin Klemme Range Research Station is located in northern Washita County about five miles west of Bessie, in western Oklahoma. The station was donated to the OSU Foundation by Mr. Marvin Klemme in 1989 and is administered by the Plant and Soil Science Department. Research is conducted in cooperation with the Department of Animal Science here at Oklahoma State University. Currently, research is under the direction of a range scientist and a range nutritionist.

The station had originally 1,150 acres of land, but with the purchase of 550 acres in 1996 this expanded the research capabilities of the station to 1,700 acres. With the exception of 21 acres of introduced pasture (Old World Bluestem), the vegetation on the land is primarily midgrass prairie range. This station is the only rangeland research station on this range-type in Oklahoma. Currently, rangeland on the station is subdivided into seven pastures of approximately equal size (120 to 140 acres), two larger pastures (250 acres) and two traps.

Research was initiated in 1990. An interdisciplinary study to establish relationships among stocking rates, vegetation and livestock responses, and enterprise economics is currently ongoing. Additionally, summer supplementation studies are currently underway.
