The LBJ Grasslands is 16,800 acres of land managed by the US Forest Service under the US Department of Agriculture. Learn more about NEON Collection Methods here.
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 36.8 inches with an average summer high temperature of 94°F and average winter low temperature of 27°F.
There is a rich legacy of land use, ranging back to the mid-19th century. Currently, LBJ Grasslands are used for recreation and hunting, livestock grazing, and fossil fuel extraction. Ongoing ecological monitoring is performed at the site, along with prescribed burning.
Site Specific Topics
NEON collects the standard suite of data at CLBJ, 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.
LBJ Grasslands is a cross timbers ecosystem, which is a mosaic of grass dominated prairies and oak dominated forests. The dominant tree species are Quercus stellata and Q. marilandica. Important grass species include Andropogon scoparius, A. gerardii, Sorghastrum nutans, and Panicum virgatum.
Important wildlife species include pronghorn (Antilocapra americana), black-tailed prairie dogs (Cynomys ludovicianus), horned larks (Eremophila alpestris), and mountain plovers (Charadrius montanus).
