A recent BioScience paper provides the first comprehensive inventory of the world's biological field stations. Its authors report 1,268 stations are operating in 120 countries - from the tropics to the tundra, monitoring terrestrial, freshwater, and marine ecosystems. Long-term data collected by biological field stations are essential for underpinning environmental research, assessing environmental policies, and advancing conservation goals.

Take the case of acid rain. Its discovery in North America was made possible by environmental data collected at a biological field station nestled in the White Mountains of New Hampshire. Hubbard Brook Experimental Forest is just one of the many biological field stations located around the globe that are keeping a pulse on the health of our planet.

Gene E. Likens, President Emeritus of the Cary Institute of Ecosystem Studies, is a coauthor on the paper, "Understanding complex environmental problems relies on biological field stations. Our acid rain work, which informed the 1990 Clean Air Act, was based on more than 26 years of long-term data. Biological field stations are a critical part of the global research infrastructure. Yet many are vulnerable to closure and need to do a better job of communicating their importance to decision makers, funders, and citizens."

Biological field stations are under continuous risk of closure due to financial insecurity, lack of public support, and weak governance. Some 38% are tied administratively to colleges and universities, with the rest overseen by museums, government organizations, and not-for-profits.

The author's urge the creation of a sustainable framework for biological field stations that recognizes their regional, national, and global importance. They also highlight a need to integrate with larger initiatives, such as the Global Lakes Environmental Observatory Network and the Intergovernmental Platform on Biodiversity and Ecosystem Services.

Klement Tockner, Director of the German Leibniz-Institute of Freshwater Ecology and Inland Fisheries and lead author on the study explains, "Biological field stations are essential to managing the rapid environmental change taking place globally. We need a sustainable vision to ensure their success - one that includes political support, increased public awareness, modernized cyber infrastructure, and improved data sharing. At the same time, we need to expand stations in areas that are underrepresented ecologically and geopolitically."

Most biological field stations are located in pristine or remote areas, like the Tundra Ecosystem Research Station situated in Canada's Southern Arctic Ecozone. Far fewer are in urbanized areas, like the Ecological Rhine Station situated on a former ship in Cologne, Germany. There is a vital need to record more environmental data in human-dominated systems, such as cities, and in sensitive areas such as deserts, savannas, mountainous regions, and offshore locations.

Undergraduate and graduate training is another benefit provided by biological field stations. These 'living laboratories' play a key role in educating the next generation of environmental scientists, and offer collaborative, hands-on research opportunities.

Likens concludes, "Given the myriad of problems facing our forests, freshwaters, and oceans - networked, sustainable biological field stations are essential. The information they collect is relevant to addressing most of today's pressing environmental problems - from air and water pollution to the movement of invasive pests and pathogens. They deserve our strong support and protection."
