Lily  Acidic Scree  Acidic Scree is a particular form of scree,
occurring in the uplands at moderate altitudes where summers are

varies, with some being relatively mobile and others more
stable. They support a colonising vegetation community, usually
dominated by ferns such as parsley fern (Cryptogramma crispa)
