SUMMARY Potential capacity of the forest as a regulating hydrological factor of the water courses One of the most important abilities possessed by forests in the zone of their growth is their retention capacity, which as a hydrological factor is of decisive significance for the natural regulation of the water amount in the soil and of the water level of brooks and rivers. As water supply in the Adriatic karst region is of primary importance for the vegetation and the population living there, it is considered useful to remind of this function and peculiarity of the forests, so that besides other problems, also the importance of their retention capacity might be understood as well as possible, and the necessary silvicultural and forests protective measures applied. Therefore this ability of the forests should be conserved and intensified, while also through new forests should be expanded to an as large area of today´s denuded karst as possible.
