Molluscs

An under recorded group in the district, their full distribution is not known as records come solely from visiting recorders at only a few sites. The list is believed to be incomplete and several species known to be common in similar habitats elsewhere have not yet been recorded in the district. Surveys are needed to update this list with priority being given to Priority Habitats.
