what is an acid grassland
Often associated with lowland heathlands, parklands or coastal cliffs, lowland acid grassland typically occurs on nutrient-poor, free-draining soils with a pH ranging from 4 to 5.5.ird species of conservation concern use acid grassland for breeding or wintering and include woodlark, stone-curlew, lapwing, chough, hen harrier and merlin. Adders and other reptiles bask on the bare ground, and small heath butterflies dance between flowers.
