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. Fauna
Important wildlife species include white-tailed deer (
Odocoileus virginianus), Texas horned lizard ( Phrynosoma cornutum), and coyote ( Canis latrans.) Soil
The dominant soil type is Cordell silty clay loam.
Doxey shale. Permian.
