The Troja hills and slopes are located on the right bank of the Vltava River on the northern periphery of Prague. The mollusc fauna of certain parts of the territory has been regularly observed by Vojen Ložek since 1987. In 2021–2022 these parts were revised together with other sites in the Drahaň – Troja Natural Park. At 63 localities, 65 mollusc species (56 land gastropods, 9 aquatic species) were recorded. Due to overgrowing of abandoned fields and pastures, forest gastropods dominated (30.8%), followed by ubiquists (30.8%). The open-ground dwellers used to be more common but now declined to 16.9%. These are supplemented by hygrophilous, wetland (7.7%), and aquatic species (13.8%) on the bottoms of some valleys.
