Español Livingston Island belongs to the South Shetland Island group in Maritime Antarctica. It lies between Snow Island and Greenwich Island, approximately 110 km from the Antarctic Continent, separated by the Bransfield Strait. The Southern Giant Petrel Macronectes giganteus is the only ACAP-listed species breeding on Livingston Island, at two known localities, Byers Peninsula and Hannah Point (ACAP Breeding Site No. 86). Byers Peninsula is an ice-free rocky promontory supporting vascular plants, mosses and lichens.

A population estimate for Southern Giant Petrels which breed mainly along the coastline is of c. 2793 individuals with 238 nests found over 17 km between Ocoa Point and Cerro Negro in 2008/09. An early estimate was of 216 pairs in 1965, suggesting little change over four decades, although the count areas differed somewhat.
Byers Peninsula has been designated as an Antarctic Specially Protected Area (ASPA No. 126; originally designated as a Specially Protected Area in 1966). In terms of the ASPA’s 2002 management plan entry is only by permit issued by an appropriate national authority. The peninsula is also a BirdLife International Important Bird Area (ANT054), designated for its Antarctic Tern Sterna vittata and Kelp Gull Larus dominicanus populations.
