Site description
This unnamed Islet lies about 150 m from shore near the head of Lepas Bay at the extreme northwest corner of Graham Island. The islet is small (about 0.8 ha) with a steep-sided rocky shore, and a lush covering of grasses and forbs under an open stand of wind-swept, stunted Sitka spruce. The burrow- nesting storm-petrels nest throughout this fragile habitat. At very low tides, the island is connected to the sandy beach of Lepas Bay.

Key biodiversity
Nationally significant numbers of nesting Fork-tailed Storm-Petrels occur on Lepis Bay Islet. During surveys completed in 1977 a total of 3,500 breeding pairs were estimated, which is about 2% of the national population. This island supports at least the 13th largest Fork-tailed Storm Petrel colony in British Columbia (about 40 colonies are known). The island is also a breeding site for Leach's Storm-Petrels with the estimated number of 4,500 pairs approaching the 1% threshold for the western Canada population. In addition to supporting storm-petrels, the Islet also supports large numbers of Pigeon Guillemots (173 birds were estimated in 1986). This represents about 1.5% of the national population for this species. Small numbers of Cassin's Auklets, Glaucous-winged Gulls and Black Oystercatchers are also found nesting here.
