Description Steppe grasslands in the Pavlov Hills belong to the most valuable natural heritage in the Czech Republic. They grow on the southeast facing limestone slopes of Děvín hill and are formed by a mosaic of two dry grassland vegetation types (alliance Festucion valesiaceae and Bromo pannonici-Festucion pallentis). In times of the Pálava game-preserve, especially in the 1970s, these grasslands were threatened by mouflon (Ovis musimon) and wild goat (Capra aegagrus) overgrazing and related disturbances. The degradation of the steppe caused especially by mouflon was recorded by several scientists (GRULICH 1978, KŘIVÁNKOVÁ 1986, UNAR 1987, KOCHOVÁ 1990, KAILER 1993, UNAR et al. 1993). This resulted only in one-time reduction of the mouflon herd and removing a herd of wild goats. However, the history is repeating as the number of mouflons is reaching 200, i.e. the number reached in the 1970s.Moreover, the present-day situation is enhanced by a development of population of invasive plant Isatis tinctoria, which is both directly and indirectly supported by mouflon activity. The state of one of the largest steppe patch in southern Moravia is calling for attention and complex solutions.
