The 1,560-acre Klemme Range Research Station is a grassland site managed for livestock grazing and pasture, located in the middle of the Rolling Red Plains Resource Area. The Rolling Red Plains extends from south of the Red River to north of the Oklahoma/Kansas border consisting of approximately 9.4 million acres, which occupies a significant portion of Western Oklahoma excluding the Oklahoma Panhandle.
The site lies in a temperate humid subtropical climate (Köppen: Cfa), with frequent variations in weather daily and seasonally, except during the consistently hot and humid summer months. The average annual precipitation is 30.70 inches with an average summer high temperature of 94°F and average winter low temperature of 26°F.
The site, which is owned by Oklahoma State University (OSU) and run as part of the Oklahoma Agricultural Experimental Station (OAES), is made up of land donated by Marvin Klemme. OSU conducts ongoing research and monitoring at the site.
The primary management concern is livestock grazing, pasture and grazing quality, and controlled burning.
Site Specific Topics
NEON collects the standard suite of data at OAES, flux tower measurements and organismal data; however, data from this particular location supports greater understanding of land use change, climate change (particularly its role in multidecadal ENSO variability), and infectious disease and invasive species.
The predominant ecosystem at OAES is rolling mixed-grass prairie. Vegetation cover is dominated by mid-grass prairie species such as Tridens muticus, Aristida purpurea var. purpurea, and Bouteloua curtipendula. Important forbs and sub-shrubs include Gutierrezia sarothrae, Amphiachyris dracunculoides, and Centaurea americana.
Important wildlife species include white-tailed deer (Odocoileus virginianus), Texas horned lizard (Phrynosoma cornutum), and coyote (Canis latrans.)
The dominant soil type is Cordell silty clay loam.
