The peninsula has been designated an Antarctic Specially Protected Area (ASPA 126) for its outstanding environmental values (specifically its biological diversity and terrestrial and lake ecosystems), and a combination of other values including scientific (terrestrial biology, limnology, ornithology, palaeolimnology, geomorphology and geology), historic (artefacts and refuge remains of early sealers) and wilderness values. It has diverse and well-developed vegetation, numerous lakes and freshwater pools which support the restricted-range insects Parochlus steinenii and Belgica antarctica, and well-preserved sub-fossilwhale bones in raised beaches. It also has the greatest concentration of historical sites in Antarctica, containing the remains of refuges, with their contemporary artefacts, and shipwrecks of early 19th century sealing expeditions.[4]
The eastern boundary of the protected area was shifted eastwards to 60º53'45"W in 2016 to include besides Byers Peninsula also all ice-free ground and ice sheet west of Clark Nunatak and Rowe Point, increasing the overall surface area of the protected territory to 84.7 km2 (32.7 sq mi).[5] Excepting Vardim Rocks, no offshore islets or rocks are protected. In particular, Rugged Island, Window Island and Astor Island are not protected.
Two restricted zones in the protected territory that are of scientific importance to Antarctic microbiology have been further designated with greater restriction placed on access with the aim of preventing microbial or other contamination by human activity: Ray Promontory in the west, and northwestern Rotch Dome, northern Urvich Wall Ridge and adjacent deglaciated ground on Ivanov Beach in the east.[5]
