Area: 7.38 hectares.

Reasons for Notification:

This site is notified because of the occurrence of the internationally rare flowering plant Rumex rupestris (shore dock). The species is a European coastal endemic that is threatened throughout its range with its world status recorded as vulnerable.

General Description:

Blackstone Point is located on the South Devon Coast between the Erme and Yealm estuaries. The site lies on the cliffs slopes and raised beach of overlain quaternary and periglacial deposits forming head, which provides the ideal habitat for the shore dock. The underlying geology of the site consists of slates from the Dartmouth Group of the Lower Devonian period. This provides the freshwater seepage habitats, which are needed by the shore dock communities.

Blackstone Point is of special interest because it supports the second largest rocky foreshore communities of shore dock in the United Kingdom and the largest population in Devon.

The site is provides nesting habitat for the rare cirl bunting for which the south Devon coast is the species stronghold within the United Kingdom.
