The project aims at ensuring sustainable conservation of underground bats habitats in five carstic key-areas, involvement of volunteers in the bats conservation process, and at public awareness and involvement in bats protection. To ensure the conservation of the bats populations, the grantee will prepare the standardized data sheet for Natura 2000 sites, making GIS database, planting warning boards at the cave's entrances and closing the entrances where the bat colonies are on the way of extinction. By involving the young representatives of the local communities where the project is implemented in camps and by connecting all the stakeholders in the area (local authorities, NGOs, schools) the importance of bat colonies and their protection will be achieved.
