[5] The Society was founded on 21 April 1911 at the Palace Hotel in Copenhagen as the 'Society for Nature Conservation (Forening for Naturfredning).
For many years, its focus was on promoting public access to beaches and forests, particularly to the Øresund Strait and the Jægersborg Deer Park.
By 1912 it was campaigning against litter, with the slogan "Sandwich wrappers and eggshells don't look pretty in forest pools!
However, although competition with similar bodies has now led to a fall to some 140,000 members,[5] it remains the largest nature conservation and environmental organisation in Denmark.
[10] As well as books and leaflets, the Society publishes the quarterly journal Natur og Miljø ('Nature and Environment'),[11] with a circulation of around 160,000.
