“…According to the theoretical and methodological framework, the primary criteria for selecting any landform or landform assemblage as a geomorphological site were as follows: representativeness as a landscape component at the local or regional scale; scientific and scenic interests; relationships with other natural and cultural assets; symbolic significance; and possibilities of observation. An index card was created, including the location data (name, reference code, country, municipality, position, altitude and Pereira and Pereira (2010) and Vieira et al (2014) geographic coordinates), the indicators of interest (scientific, educational, ecological, cultural and aesthetic), and the use/management conditions (taking into account potential uses, conservation degree, current exposure and threats), for the sites' field records. At the end section of the index card, a summary description, cartography and images were attached.…”
