The primary objective of this study was to investigate patterns of abundance and diversity among reptiles and amphibians within the protected area of Mount Chelmos, located in Peloponnese, Greece. Our aim was to examine the drivers influencing abundance (for lizards, snakes, chelonians, anurans, urodels) and diversity (for reptiles and amphibians) within the finely-scaled study area and identify biodiversity hotspots. Land cover significantly impacted the abundance and diversity of all studied groups. Elevation had a significant impact on the abundance of snakes, chelonians, and anurans, as well as on reptile and amphibian diversity. Climate influenced all groups except chelonians. Slope significantly impacted anuran abundance and amphibian diversity. Aspect primarily influenced the abundance of lizards, anurans, and urodels, as well as reptile diversity. We have also identified abundance and diversity hotspots, emphasizing the importance of conservation and management efforts. In reptiles, abundance hotspots were predicted in the west, east, and south of the mountainous massif, whereas amphibian abundance hotspots were mapped to the west and east-southeast of the massif. Regarding diversity, the patterns were similar for both reptiles and amphibians, with hotspots emerging in the west, south, and southeast boundaries of the study area, and a few spots north of the mountainous region. Notably, many of these hotspots coincided with areas susceptible to human exploitation and vehicular transit.
