Deadman (grid reference ST234156) is a 28.8 hectare (71.2 acre) biological Site of Special Scientific Interest on the edge of the Blackdown Hills, near Buckland St Mary 5 miles (8.0 km) south of Taunton in Somerset, notified in 1987. Deadman is one of the best remaining examples of a mixed valley mire in Somerset. It contains a rich mosaic of wet heath, bog pools and birch/willow carr grading into acid marshy grassland. These communities support several species of plant which are rare in the county. Ground water issues from numerous springs within the greensand producing a locally raised water table and shallow peaty surface horizon. It is at these points that bog communities develop, characterised by the floating leaves of bog pondweed (Potamogeton polygonifolia), bog bean (Menyanthes trifoliata) and marsh St John's-wort (Hypericum elodes). In places this wet heath has undergone a transition to birch (Betula sp.) and willow (Salix sp.) carr. This provides an important habitat for breeding nightingales and grasshopper warblers.

Ruttersleigh (grid reference ST250165) is a 97 hectares (240 acres) biological Site of Special Scientific Interest between Buckland St Mary and Staple Fitzpaine on the north-facing slope of the Blackdown Hills. in Somerset, notified in 1991. This site comprises a mosaic of broadleaved woodland, scrub, bracken, mires and unimproved grassland which provides the habitat for several species of butterfly which are now scarce in Britain. The site is also important for its lichens. The ground flora includes a number of species normally found only in ancient woodland such as woodruff (Galium odoratum) and wood anemone (Anemone nemorosa). Wood horsetail (Equisetum sylvaticum), which is rare in Somerset, is abundant and widespread on this site also being found in the areas of bracken (Pteridium aquilinum). The epiphytic lichen flora is also typical of ancient woodland and includes species such as Lobaria pulmonaria. The nationally scarce Opegrapha corticola and the nationally rare Chaenotheca stemonea also occur. The woodland rides and glades provide ideal habitat for the nationally scarce wood white (Leptidea sinapis) butterfly, this site having by far the strongest colony known in Somerset. The grassland provides habitat for the nationally scarce marsh fritillary (Eurodryas aurinia) butterfly. The breeding birds include nightingale (Luscinia megarhyches), common redstart (Phoenicurus phoenicurus) and wood warbler (Phylloscopus sibilatrix). Adder (Vipera berus), grass snake (Natrix helvetica), slowworm (Anguis fragilis) and common lizard (Lacerta vivipara) have all been recorded from the site.
