Located at the Sevilleta National Wildlife Refuge north of Socorro, the University of New Mexico's Sevilleta Long-Term Ecological Research site (LTER) is part of the U.S. National Science Foundation LTER network. Scientists of the LTER program investigate ecosystem responses to environmental changes. These changes include both natural and human disturbances such as global warming, acid deposition, land use, wildfires, drought and the El Nino-Southern Oscillation. Long- term studies of the Sevilleta LTER improve our understanding of the following ecosystems: Chihuahuan Desert, Great Plains Grassland, Great Basin ShrubSteppe, Pinon-Juniper Woodland, Bosque Riparian Forests and Wetlands, Ponderosa Pine Forests, Mixed-Conifer Montane Forests, Sub-alpine Forests and Meadows. Ecological responses to change are evaluated at various ecological levels (organismal, population, community, ecosystem, landscape, etc.) and at multiple spatial and temporal scales.
