This review article discusses the importance of inventorying and quantitatively assessing geosites and geodiversity sites as essential steps in geoconservation strategies. It highlights the need for clear selection criteria and proposes a systematic approach to identify and evaluate these sites. The paper emphasizes the scientific value of geodiversity elements, which are crucial for understanding Earth's geological history and processes. It also addresses the risks of degradation due to human activities and the importance of protecting these sites for future research and education. The article outlines the concepts of geosite and geodiversity site, distinguishing them from geoheritage and discussing their different values. It proposes criteria for selecting geosites based on representativeness, integrity, rarity, and scientific knowledge, and for geodiversity sites based on educational and touristic potential. The paper also presents methods for quantitative assessment of scientific value, educational use, touristic use, and degradation risk. It emphasizes the need for a solid methodological approach to ensure effective inventory and management of geosites and geodiversity sites. The article concludes that the selection of geodiversity elements is a complex task, and a systematic approach is essential for their protection and management. The proposed methods aim to support geopark strategies and ensure the sustainable use of geodiversity for scientific, educational, and tourism purposes.This review article discusses the importance of inventorying and quantitatively assessing geosites and geodiversity sites as essential steps in geoconservation strategies.
