NSF Long-Term Ecological Research is a program supporting sustained, interdisciplinary ecological studies across spatial and temporal scales. It links sustained observations, experimental manipulation, and archival records to understand patterns and processes affecting ecosystems such as Yellowstone National Park, Everglades National Park, Arctic National Wildlife Refuge, Amazon rainforest, and Great Barrier Reef. The program fosters collaboration among institutions including the National Science Foundation, Smithsonian Institution, U.S. Geological Survey, Princeton University, and University of California, Berkeley.

Overview

The program coordinates a distributed network of field sites, collaborative centers, and data repositories to study long-term change in ecosystems like Sierra Nevada, Chesapeake Bay, Gulf of Mexico, Hawaiʻi Volcanoes National Park, and Gulkana River. It integrates methods from investigators at Columbia University, Stanford University, Duke University, University of Washington, and University of Arizona to address drivers such as climate variability documented by Intergovernmental Panel on Climate Change, land-use change noted by United Nations Environment Programme, invasive species studied by U.S. Fish and Wildlife Service, and disturbance regimes recorded by National Oceanic and Atmospheric Administration. The network emphasizes open data stewardship aligned with practices from Global Biodiversity Information Facility, DataONE, and EarthCube.

The distributed network comprises sites across biomes including alpine, boreal, temperate forest, grassland, freshwater, estuarine, and coastal marine environments with examples at Niagara Falls, Sevilleta National Wildlife Refuge, Hubbard Brook Experimental Forest, Moorea Coral Reef LTER, Santa Barbara Coastal LTER, and Luquillo Experimental Forest. Site teams are based at universities and agencies like University of New Mexico, Oregon State University, University of Florida, University of Georgia, and California Institute of Technology, and they collaborate with international partners such as Max Planck Society, Brazilian National Institute for Space Research, and CSIR South Africa. The network facilitates comparative research across gradients studied by programs at International Long-Term Ecological Research Network hubs and city partnerships including New York City and Los Angeles urban ecology nodes.

Major themes include ecosystem nutrient cycling informed by studies at Hubbard Brook Experimental Forest and Baltimore Ecosystem Study, climate change impacts examined at Toolik Lake, Arctic National Wildlife Refuge, and McMurdo Dry Valleys, disturbance and recovery investigated after events such as Mount St. Helens eruption, Hurricane Katrina, and California wildfires, and biodiversity dynamics tracked using frameworks from Convention on Biological Diversity and datasets comparable to Global Ocean Observing System. Contributions include advancing theories like succession refined from Clementsian succession debates and metapopulation concepts expanded alongside work by Island Biogeography researchers, improving models used in Intergovernmental Panel on Climate Change assessments, and informing management in agencies such as U.S. Fish and Wildlife Service, National Park Service, and Environmental Protection Agency.

The program is administered through directorates at National Science Foundation with oversight from advisory committees including experts from National Academy of Sciences, former chairs from Ecological Society of America, and representatives of institutions like University of California system, State University of New York, and University of Michigan. Funding streams combine core awards, supplements, and cooperative agreements involving partnerships with National Oceanic and Atmospheric Administration, U.S. Geological Survey, Department of Energy, and philanthropic supporters such as the Gordon and Betty Moore Foundation and Andrew W. Mellon Foundation. Governance practices follow federal guidelines codified by Office of Management and Budget and reporting consistent with Government Accountability Office reviews.

Data infrastructure aligns with standards used by Global Biodiversity Information Facility, DataONE, and EarthCube and employs repositories and tools developed in collaboration with University of California, Berkeley's research computing, Princeton University's data services, Utah State University's data centers, and commercial platforms used by Amazon Web Services for large-scale storage. The network maintains metadata protocols compatible with Darwin Core, links to climate records from NOAA National Centers for Environmental Information, and integrates remote sensing from Landsat, MODIS, and missions by NASA. Cyberinfrastructure initiatives include efforts paralleling National Center for Atmospheric Research science gateways and software from projects at University of Illinois Urbana–Champaign and Carnegie Mellon University.

The program supports education through graduate training at University of Wisconsin–Madison, undergraduate programs at Colorado State University, K–12 outreach with partners like Smithsonian Institution and American Museum of Natural History, and citizen science collaborations similar to projects by National Audubon Society and Monarch Watch. Outreach informs policy debates with briefs cited by U.S. Congress staff, technical guidance used by Environmental Protection Agency rulemaking, and testimony provided to committees in House Committee on Science, Space, and Technology and Senate Committee on Energy and Natural Resources. Its findings contribute to international assessments conducted by Intergovernmental Panel on Climate Change and conventions such as Convention on Biological Diversity.
