A method for assessing scientific and additional values of geomorphosites

Abstract. Over the last two decades, several methods have been developed to reduce subjectivity of geomorphosite selection through use of transparent assessment criteria. Most of these methods propose criteria such as integrity, rarity, representativeness and palaeogeographical importance for the evaluation of the «scientific value» of sites. For the assessment of their global quality, «additional values» of ecological, cultural, aesthetic and economic nature have, at times, been taken into consideration. This paper proposes a new assessment method that integrates both sets of values into the evaluation of geomorphosites. The method is described and its implementation in two different cases presented: compilation of an inventory of geomorphosites in the National Park of Adula (Ticino, Switzerland) and evaluation of the geocultural heritage of the Trient area (Valais, Switzerland).
