Due to the renewed interest for sites of geological interest, both in nature conservation and tourist sectors, numerous regional and national geosite inventories have been carried out in several countries during the last two decades. Several research groups discussed methodological issues, in particular concerning the assessment, and proposed various assessment methods. The University of Lausanne developed a method for assessing the scientific and additional values of geomorphosites in 2007. The method was widely used in regional inventories in Switzerland and abroad. This paper presents a new version of the method and discusses four main issues: (1) the assessment methodology is included in a larger process, from the selection of potential geomorphosites to their use and evaluation by stakeholders; (2) a particular attention is put on the selection of potential geomorphosites that will then be assessed and a simple approach crossing a spatial selection (the selected geomorphosites should be representative of the regional geomorphological processes) and a temporal one (the selected geomorphosites should cover the whole temporal stages of the regional morphogenesis, with both relict and active landforms) is proposed; (3) a new part is added in the assessment method; it concerns the use characteristics and fills a gap in the existing method; (4) finally, the paper discusses mapping and representation issues: specific maps are produced at two levels: simple geomorphological maps accompany the assessment of each geomorphosite and synthetic maps, covering the whole study area, are produced for the communication of results to stakeholders. For this, four types of representation (qualitative, univariate, bivariate, multivariate) are proposed. The method is illustrated by three examples of inventories carried out in Western Switzerland and Haute-Savoie (France).

This paper has two main objectives: (1) to assess the heritage value of four geomorphological landscapes in Southern Iceland from a geomorphological perspective and (2) to see to what extent the heritage values assigned by different local stakeholders overlap with this assessment. The concept of “geomorphological landscape”, that we define as a landscape whose geomorphological component is of heritage interest, is a scale of analysis that can be understood by different groups of people and that reflects subjective perceptions of the landscape. The evaluation of the heritage value of four geomorphological landscapes has shown that their geoscientific, aesthetic and cultural values are particularly high. Indeed, thanks to their rarity, representativeness, integrity and paleogeographic interest, all four sites have a geoscientific value ranging from 0.81 to 0.94 (the maximum possible score is 1). They also constitute spectacular and beautiful landscapes and have acquired a relevant cultural value because of the major impacts that volcanic eruptions and glaciers advances have had on the local population. Not surprisingly, the heritage awareness of managers of protected areas is high. The interviews also show that other types of stakeholders, such as tourism services providers, tourism promoters and representatives of local authorities, are also aware, to some extent, of the high geoscientific value. The societal and institutional recognition of the heritage value of these geomorphological landscapes is closely linked to their use as territorial resources for tourism.

Abstract. Geoheritage is a component of geodiversity constituted by all the elements of geodiversity recognized by society for their particular values. The definition of these values, including the importance of geoheritage for biodiversity, plays a key role in the process of heritage recognition and geoconservation policymaking. In mountain environments, dynamic geomorphosites have a strong influence on plant diversity because the active geomorphological processes responsible for their formation act as renovators for habitats of pioneer species. In this paper, we propose criteria to assess the ecological value of dynamic mountain geomorphosites. We show that the interest of plant communities (species richness and presence of rare or protected species) and the influence of geomorphological processes on plant communities (disturbances, surface movement and soil) are fundamental criteria for assessing the ecological value in an exhaustive and objective way and that the question of the scale (local and national scales) is also a crucial parameter. We then illustrate this methodological proposal by evaluating the ecological value of three dynamic geomorphosites and a talus slope in the western Swiss Alps.
