In order to maintain biodiversity and ecological balance, heritage meadows will be managed as necessary.

Description of the action

The expansion of scrub encroachment into important grasslands (heritage grasslands). It is advisable to cut the scrub gradually (e.g. 1/15 of the scrub every year or 1/5 every three years). In doing so, maintain a variety of species, ages and structures. Livestock grazing can also be used to limit the vegetation.

Why?

Lubricated boggy grasslands are some of the most species-rich communities, providing habitats for plants and insects alike. It is important to achieve a balance of open sunny areas and scrub/grassland in these areas in order to maintain habitats. Shrub and bush areas that are sunny and shelter from the wind provide a warm microclimate for insects and reptiles. Variable height scrub and grassland provide variety and habitat for a range of species. Shrubs and scrub also provide buffer habitats between grassland and woodland. In addition, they reduce erosion, sedimentation and nutrient run-off into water bodies. Shrubs and bushes can also act as windbreaks. When grazing, avoid excessive trampling of the water’s edge by livestock and avoid contaminating water with manure. When antiparasitic drugs are administered to livestock, they have a strong effect on many invertebrates living in the manure and the animals that feed on them.
