The ecological value of abandoned quarries has gained increasing scientific attention in the last few decades, resulting in a paradigm shift in restoration programs regarding the use of natural processes. The linkages between biotic and abiotic diversity, such as landform and microclimatic diversity have been analyzed only slightly, however. In this paper, we use an interdisciplinary approach that includes vegetation mapping, geomorphological mapping, microclimatic measurements and modeling to reveal the specific two‑way linkages between abiotoc and biotic diversity. The present case study shows that in only 60 years landform diversity allowed the development of nine distinct biotopes with 134 identified species. At the same time, the vegetation diversity at these human‑induced biotopes is of high ecological value as it displays significant similarities with natural biotopes in the region (e.g., scree slope and rock cliff biotopes). Based on the results presented, the paper aims to contribute to current restoration programs involving processes of spontaneous succession and landforming.
