Protected Landscape Area (PLA) Moravian Karst is the most important karst area in the Czech Republic territory. Unique living organisms, karst phenomena, archeological finds and cultural monuments can be found here. Karst landscape has attracted the attention of man since long ago – at first it was the cave as a shelter, later mineral resources. Main attention is focused on the extraction of high quality limestone. This activity is in conflict with the interests of nature and landscape, so there are mining plants shut down gradually. Active quarries exist outside the PLA – Mokra“ quarry, one of the largest limestone quarries in the Czech Republic. It is a progressive company, which would modernize its technology to minimize impacts on the environment. This company is successful in reclamation projects, in collaboration with the Land Trust Hady is promoting natural restoration of quarries by controlled succession. The main mission of the Land Trust is to preserve sites of the outstanding natural value Hady near Brno, and link nature conservation with environmental education.
