The Prawle Point and Start Point Site of Special Scientific Interest (grid reference SX741371 to grid reference SX819381) is a 341.2 hectare biological and geological Site of Special Scientific Interest in southern Devon, notified in 1976.
This section of coast features an almost continuous 5 km stretch of soft head deposits on a raised hard rock platform.
These cliffs are south facing and feature sheltered coves, offering ideal conditions for thermophilic (warmth-loving) invertebrates.
Currently, this is only known from three sites in the UK: East Prawle, West Weare (Portland, Dorset), and Thursley Common (Surrey).
Prawle is also an important site for the Cirl bunting, and supports a rich lichen assemblage.
