The larger islands have a forest cover of western hemlock, western red cedar and sitka spruce with an interior ground cover of salal, salmonberry, elderberry and in some areas, moss, grasses and forbs. The perimeter of some of the large islands and some of the smaller vegetated islets, are covered with dense growths of salmonberry and other shrubs. Other islets are mostly bare rock with small areas of lush grass and forbs.
The shorelines of most of the islands are comprised of steep rock dissected by gorges and crevices. Areas with shelving rock and boulders are used by Harbour seals as haul-out sites.
Approximately 161,600 pairs of Rhinocerous Auklets have been estimated on Pine and Storm Islands. This represents approximately 26% of the global and as much as 45% of the national population. Large numbers of storm-petrels also nest on the Reserve, including 60,000 Fork-tailed Storm-Petrels (2.4% of the global, and 32% of the national population). An even larger population of Leach's Storm Petrels (276,600 pairs - over 3% of the global, almost 10% of the eastern Pacific, and 50% of the western Canada population) nest on all the islands except Naiad Islets and Pine Island. Small colonies of Cassin's Auklets (6,710 pairs) also occur among the other burrow-nesting seabirds (mostly on the Buckle Group) but not in nationally significant numbers. In addition, all of the islands except Pine support nesting Black Oystercatchers, with 23 pairs being present. This represents over 2% of the Canadian Black Oystercatcher population. Pigeon Guillemots also occur around all of the islands, with nearly 3% of the national population being present.
Large numbers of Glaucous-winged Gulls are also present (275 pairs) and Bald Eagles nest on most of the islands. The surrounding marine waters are also important for migrating Red-necked Phalaropes. Flocks of thousands feed on tide lines during July and August.
