The Ecological Society of America

About us

The Ecological Society of America (ESA) is a nonpartisan, nonprofit organization of scientists founded in 1915 to:

promote ecological science by improving communication among ecologists;
raise the public’s level of awareness of the importance of ecological science;
increase the resources available for the conduct of ecological science; and
ensure the appropriate use of ecological science in environmental decision making by enhancing communication between the ecological community and policy-makers.
Ecology is the scientific discipline that is concerned with the relationships between organisms and their past, present, and future environments. These relationships include physiological responses of individuals, structure and dynamics of populations, interactions among species, organization of biological communities, and processing of energy and matter in ecosystems.
