A Century of Conservation: The Danish Society for Nature Conservation Founding and Early Mission

Danmarks Naturfredningsforening has actively contributed to the creation of national parks like National Park Thy (pictured), the first of its kind in Denmark. Over the decades, the Society’s campaigns also led to the protection of iconic landscapes such as Møns Klint and Mols Bjerge

Denmark’s Danmarks Naturfredningsforening, or Danish Society for Nature Conservation, was founded on April 21, 1911, in Copenhagen with a pioneering vision. Unlike earlier scientific circles that sought to preserve nature for its own sake, this new association focused on protecting natural areas for the people, ensuring public access to beaches and forests that were increasingly being fenced off by private landowners. In 1912, the young society launched its first anti-litter campaign with the cheeky slogan “Sandwich wrappers and eggshells don’t look pretty in forest pools!" spurring public awareness about pollution. Early priorities also included fighting roadside billboard blight and saving beloved landscape features like old trees and coastal boulders. These grassroots campaigns established the society's reputation as a guardian of Denmark’s natural heritage. 

Growth and Landmark Achievements 

By 1925, the organization had grown to over 3,000 members and officially adopted the name Danmarks Naturfredningsforening, affirming its nationwide role in conservation. Its influence soon extended to the halls of government. In 1917, the society's advocacy helped push through Denmark’s first Nature Conservation Act, which, for example, allowed the state to expropriate private land for conservation, a bold idea at the time. A major milestone came in 1937, when Prime Minister Thorvald Stauning backed a landmark law empowering the society with a unique legal authority: the right to propose protected areas (known as “fredninger”) on its own initiative. This made Danmarks Naturfredningsforening the only organization in Denmark legally allowed to initiate conservation cases, a status it still holds today. The society used this power to great effect. By the mid-20th century, it had secured the preservation of numerous unique landscapes. Thanks to its efforts, natural treasures such as Skagen’s dune-rich Grenen, the white cliffs of Møns Klint, and the rolling hills of Mols Bjerge were officially protected for future generations. 

Membership in Danmarks Naturfredningsforening surged as Danes embraced the environmental cause. The society's member base, rooted in a vibrant democratic structure of local branches, climbed from a few thousand in the 1920s to a peak of over 260,000 in 1987. This made it not only the largest green organization in Denmark but also one of the most broadly supported environmental NGOs in the world for a country of Denmark’s size. During the 1970s, the society broadened its scope in step with the emerging environmental movement. In 1971 it expanded its agenda beyond nature conservation to include issues like air and water pollution, coinciding with Denmark establishing the world’s first Ministry of Environment that same year. Danmarks Naturfredningsforening thus transitioned into a comprehensive environmental organization, addressing threats to clean air, clean water, and biodiversity long before “environmentalism” entered the mainstream. Its golden jubilee and beyond saw an organization at the forefront of public environmental engagement; by its 75th anniversary in 1986, membership stood at 225,000, and the Society celebrated with nationwide events and even a lottery to fund nature projects. 

Modern Mission and Impact 

Today, after over 114 years, Danmarks Naturfredningsforening remains the beating heart of Denmark’s environmental movement. It is currently the country’s largest environmental NGO, with more than 137,000 members and some 1,500 active volunteers driving its activities on the ground. The society's mission has evolved with the times: what began in 1911 as a crusade for public access and nature preservation has grown into a broad mandate covering nature conservation, climate action, pollution prevention, sustainable resource use, and more. “We have established strategic partnerships… turning 100,000 hectares of bogland back to nature and [working] to protect 10 percent of the Danish marine environment,” notes Maria Reumert Gjerding, the current president of the Society. Under her leadership (she took the helm in 2018), the organization has teamed up with farmers, fishers, and renewable energy groups to advance practical solutions, restoring wetlands, creating marine reserves, and promoting sustainable farming that benefits both people and planet. 

Importantly, Danmarks Naturfredningsforening continues to shape national policy and public debate. It remains, by law, a formal stakeholder in environmental decision-making, and its proposals have left a visible mark on Denmark’s landscape and seascape. From spearheading annual nationwide beach cleanups to campaigning for stronger climate legislation, the Society serves as a unifying platform for citizens passionate about nature. It also invests in future generations, running Denmark’s largest nature education program for children and hosting an annual “Nature Day” to connect people with the outdoors. As a community for everyone who wants to act for nature, environment, and climate, Danmarks Naturfredningsforening continues to inspire Danes to make a difference. After more than a century, this venerable organization stands as a pillar of Denmark’s green identity, a testament to how sustained civic activism can protect a nation’s natural legacy while continually adapting to meet new environmental challenges.
