The objects of this Protocol are the conservation as well as the development, surface extension and improvement of mountain forests. To these purposes, a mountain forest economy managed in an appropriate and sustainable manner is needed. The Contracting Parties undertake to: (a) adopt methods of natural restoration of forests; (b) pursue well-structured forest resources through suitable tree species; (c) employ autochthonous forest reproduction materials; (d) prevent soil erosion. The above-mentioned aims shall be considered also in other policies with respect to pollution, ungulates' population, grazing in forests, recreational uses of forests and prevention of forest fires. Article 4 encourages cooperation amongst Parties, especially research institutes and forest and environmental organizations. In accordance with article 10, the Contracting Parties undertake to define natural forest reserves. Further, Chapter 3 of the Protocol regards research, education and information. Chapter IV deals with the implementation of these provisions and related controls. In particular, the Parties shall transmit regularly to the Permanent Committee a report relating to the measures that have been adopted on the basis of this Protocol. Thereafter, the Permanent Committee shall elaborate a report to be submitted to the Alpine Conference concerning the compliance with these provisions. The Conference shall, in case of breach of the obligations hereby established, adopt recommendations as appropriate.
