NABU (Nature and Biodiversity Conservation Union) is one of Germany’s largest and oldest environmental non-profit organisations, dedicated to protecting nature and preserving biodiversity. Founded in 1899, NABU works to safeguard habitats, restore ecosystems, and conserve endangered species—both within Germany and internationally. Through science-based conservation projects, public engagement, and policy advocacy, the organisation promotes sustainable land use, climate protection, and responsible environmental management. With a strong civil-society foundation and hundreds of thousands of supporters, NABU plays a key role in advancing nature conservation and strengthening public awareness for environmental issues.
