Heritage meadows are managed when necessary to maintain biodiversity and ecological balance.

Description of the action

Limit the expansion of shrubs into important grasslands (heritage meadows). It is recommended to cut shrubs gradually (e.g., 1/15 of the shrubs each year or 1/5 every third year). Maintain different species, ages, and structures. Grazing animals can also be used to control shrub expansion.

Why?

Limestone-rich alvar meadows are among the most species-rich habitats, providing living and growing spaces for both plants and insects. It is important to maintain a balance between open sunny areas and shrubland/brush to preserve these habitats. Sunlit and wind-sheltered shrublands create a warm microclimate for insects and reptiles. Shrubs and open areas of varying heights provide diversity and habitats for various species. Shrublands and brush also serve as buffer habitats between meadows and forests. Additionally, they help reduce erosion and prevent sediments and nutrients from entering water bodies. Shrubs and brush can also act as windbreaks. When grazing, excessive trampling of water edges by livestock should be avoided, as well as water contamination from manure. If livestock are given antiparasitic treatments, these can significantly impact many invertebrates living in manure and the animals that feed on them.
