Sorbus torminalis
Much of Maulden Wood is designated as an (SSSI) for the acidic grassland and heathland interest, and wildlife includes badger sets, foxes, and barn owls. The site is important for invertebrates and plants which are indicative of the varied clay and sandy gravel soil. One notable invertebrate is limax cinereoniger, a mollusc that is also indicative of unmanaged ancient woodlands. The rare Wild Service Tree Sorbus torminalis also grows in the drier places deep in the wood.
