Jornada Experimental Range The Jornada Experimental Range is a long-term rangeland research facility near Las Cruces, New Mexico, operated by the United States Department of Agriculture Agricultural Research Service. The site supports studies in aridland ecology, Texas A&M University-related collaborations, and cooperative projects with institutions such as New Mexico State University, University of Arizona, and federal agencies including the United States Forest Service and the Bureau of Land Management. Its work intersects with programs from the National Science Foundation, the Smithsonian Institution, and international partners like the International Arid Lands Consortium.

History

Founded in 1912 during the Progressive Era, the range evolved through administrative links with the United States Department of Agriculture, the Rockefeller Foundation-funded initiatives of the 1930s, and wartime scientific expansion associated with Manhattan Project logistics in New Mexico. Throughout the 20th century researchers from Colorado State University, University of California, Davis, Cornell University, and Utah State University contributed to seminal studies on desertification, grazing, and restoration influenced by meetings at Society for Range Management conferences. Landmark projects included collaborations with the Carnegie Institution for Science and policy-relevant assessments informing legislation debated in the United States Congress and implemented by the Natural Resources Conservation Service. Notable researchers affiliated with the site conducted experiments contemporaneously with studies at the Desert Laboratory and the Sevilleta National Wildlife Refuge.

Geography and Climate

Located within the Chihuahuan Desert near Las Cruces, New Mexico and the Rio Grande, the range occupies basin-and-range topography adjacent to Organ Mountains and the Doña Ana County landscape. Elevation gradients approach those of the Tularosa Basin and border ecosystems similar to White Sands National Park and the Mimbres River watershed. The climate is characterized by bimodal precipitation patterns paralleling records from National Weather Service stations, influenced by the North American Monsoon and episodic droughts recorded by the U.S. Drought Monitor. Soils reflect associations with the Soil Survey of Dona Ana County and classification schemes used by the Natural Resources Conservation Service, with pedons comparable to those documented in the Sonoran Desert and Mojave Desert research areas.

Research and Long-term Experiments

The facility hosts multi-decadal experiments on grazing, shrub encroachment, and vegetation dynamics performed alongside programs funded by the National Aeronautics and Space Administration and the Environmental Protection Agency. Long-term trials include treatments comparable to experiments at the Konza Prairie Biological Station and the Long-Term Ecological Research network, with data integrated into repositories associated with the USDA National Agricultural Library and the Long Term Ecological Research Network. Research topics link to modeling efforts using frameworks developed at Los Alamos National Laboratory and climate projections from the Intergovernmental Panel on Climate Change. Collaborators include scientists from Harvard University, Princeton University, Duke University, University of Colorado Boulder, and international teams from University of Oxford and the University of Cambridge. Studies have informed restoration methods paralleling those at The Nature Conservancy preserves and practices employed by the United States Fish and Wildlife Service.

Facilities and Infrastructure

Infrastructure at the site comprises field stations, instrumentation for eddy covariance flux measurements similar to those at the AmeriFlux network, and meteorological towers maintained in coordination with NOAA programs. Laboratory space supports soil carbon assays using protocols akin to those at the USGS laboratories and greenhouse facilities used by researchers from Texas Tech University. The range hosts data-management systems interoperable with DataONE and archives in partnership with the National Ecological Observatory Network. Vehicle and livestock handling facilities enable controlled grazing experiments paralleling methods from the Rangeland Resources Department at various universities, while accommodations support visiting scholars from institutions like Stanford University and Yale University.

Ecology and Land Management

The landscape supports communities of creosote bush and tarbush alongside grass assemblages including species studied in the context of blue grama and black grama dynamics. Wildlife observations connect to species lists used by the Audubon Society and monitoring protocols from the United States Geological Survey and the Fish and Wildlife Service. Management practices trialed at the range include prescribed grazing, shrub removal, and reseeding techniques informed by extension services from New Mexico State University Cooperative Extension and guidelines from the Natural Resources Conservation Service. Fire ecology experiments mirror approaches used in studies at the Wallowa-Whitman National Forest and inform regional planning by the New Mexico Department of Game and Fish. Soil-vegetation feedbacks are compared with findings from the International Union for Conservation of Nature assessments and restoration case studies documented by the Society for Ecological Restoration.

Education and Outreach

The range provides training and internships for students from New Mexico State University, University of New Mexico, and visiting scholars from University of Texas at Austin and Arizona State University. Outreach includes workshops coordinated with the Society for Range Management, public lectures in partnership with the La Union Cooperative Extension Service, and educational collaborations with the New Mexico Museum of Natural History and Science and the Las Cruces Museum of Nature & Science. Data and teaching resources contribute to curricula developed by the National Park Service education programs and summer schools organized with the Ecological Society of America. Community engagement activities involve partnerships with tribal entities such as the Mescalero Apache Tribe and regional landowners represented through New Mexico Cattle Growers' Association.
