National Ecological Observatory Network. It is a continental-scale ecological observation facility funded by the National Science Foundation and operated by Battelle Memorial Institute. The program collects long-term, open access data from 81 field sites across the United States, including Alaska, Hawaii, and Puerto Rico, to study how ecosystems are changing. Its integrated data on biodiversity, biogeochemistry, hydrology, and climatology supports research on pressing environmental challenges like climate change, land use change, and invasive species.

Overview

The network is designed as a national resource for ecological research, providing standardized, comparable data across diverse biomes from tundra to tropical rainforest. Its sites are strategically located within 20 distinct ecoclimatic domains to capture continental environmental gradients. Data collection is performed by field technicians and automated sensors, with all information processed at a central Battelle facility. The ultimate aim is to create a 30-year record of ecological change to inform scientific understanding and public policy.

Design and infrastructure

The physical infrastructure consists of 47 terrestrial and 34 aquatic sites, each equipped with a standardized suite of instrument towers, soil sensor arrays, and meteorological stations. Terrestrial sites feature flux towers to measure exchanges of carbon dioxide, water vapor, and energy between the land and atmosphere. Aquatic sites deploy sensors in streams, rivers, and lakes to monitor water quality, temperature, and dissolved oxygen. A key component is the Airborne Observation Platform, which uses LiDAR and imaging spectroscopy to conduct annual aerial surveys, capturing landscape-scale data on vegetation structure and biochemistry.

Scientific goals and research

Primary scientific goals center on understanding the impacts of climate change, land use change, and biological invasions on ecosystem structure and function. Research themes include quantifying carbon sequestration, tracking seasonal cycles of plants and animals, and documenting shifts in species distribution and biodiversity. The data enable studies on nutrient cycling, disturbance ecology, and ecohydrology. By integrating genomics with observational data, scientists can also investigate the genetic basis of organismal adaptation to environmental stress.

History and development

The concept was proposed in the early 2000s following recommendations from the National Science Board to address the need for large-scale, long-term ecological data. Planning and design were led by a consortium including the University of Colorado Boulder and Botanical Research Institute of Texas. After a competitive process, the National Science Foundation awarded the construction and operations contract to Battelle Memorial Institute in 2016. The facility achieved full operational status in 2019, following a construction phase that involved significant collaboration with agencies like the United States Forest Service and National Park Service.

Data products and access

All data are freely available through an online portal, which includes over 180 standardized data products. These range from raw sensor readings to higher-level aggregated data on leaf area index, population dynamics, and soil microbe composition. The portal provides application programming interfaces for automated data access and tools for data visualization and quality assurance. Data are used by researchers at institutions like Harvard University, Stanford University, and the Smithsonian Institution, as well as by educators and resource managers.

Partnerships and network

Operations rely on extensive partnerships with host sites, including LTER sites, university research forests, and federal lands managed by the Bureau of Land Management and United States Fish and Wildlife Service. International collaboration occurs through organizations like GEO and ILTER. Educational partnerships with entities like Project BudBurst and the Ecological Society of America help translate data for citizen science and STEM education initiatives.
