Langara Island is located at the northwest corner of Graham Island, the largest of the Queen Charlottes. The shoreline of the 3,105 ha island is dominated by sitka spruce. As one proceeds in from the sea, the forest composition shifts to western hemlock and then to predominately western red cedar. In the interior of the island there are areas of open sphagnum bog.
Langara Island supports globally significant numbers of Ancient Murrelets, a species which is listed as nationally vulnerable. Approximately 29,000 birds, or 2% of the global population, are present during breeding season. Of 26 individual islands with confirmed nesting records of Ancient Murrelets in British Columbia (the only area in Canada where this species occurs), Langara supports the fifth largest colony.
As well as Ancient Murrelets, Langara Island also supports nationally significant numbers of Pigeon Guillemots (187; approximately 1.8%) and large numbers of Pelagic Cormorants (104). Several pairs of Peregrine Falcons (ssp. pealei) are also present, a species that is listed as nationally vulnerable.
The marine waters surrounding the island are important staging areas for the breeding seabirds. In addition, an important marine feeding habitat for nationally significant numbers of the threatened Marbled Murrelet occurs from Parry Passage to Pillar Bay along the south shore of Langara island and the adjacent north coast of Graham Island.
