The Pohořská Mountains in the southern part of the Bohemian Massif represent a unique natural area situated on the border between the Czech Republic and Austria. The area was virtually inaccessible during the Cold War because of its localization close to the Iron Curtain. After 1989, the geomorphological mapping with an emphasis on rock landforms has been carried out here. We ask what geological and geomorphological conditions support the diversity of rock landforms in the Pohořská Mountains. The diversity of rock landforms in hexagonal grid cells (ca. 1 ha) was expressed as the number of rock-landform types and using the Shannon diversity index. The effects of lithology, slope, orientation, elevation, and relief curvature on the diversity of rock landforms were analysed using the Classification and Regression Trees. This analysis showed that the highest diversity occurs in grid cells with high mean relief curvature, elevation, and steep slopes.
