La Lliga per a la Defensa del Patrimoni Natural Authors Salvador Filella Cornadó Abstract DEPANA was formed in 1976, with the object of protecting the natural heritage of Catalonia. Throughout the following eight years, activity has been concentrated on three main fields: 1. increasing the level of public knowledge and awareness about the necessary balance between man and his environment. 2. fighting for the establishment of a whole network of protected areas, with the object of preserving all our different environments. 3. working towards an adequate and well-published system of laws, to enable the effective protection of our natural heritage by the State.
