Site description (2001 baseline):
Anthony Island is forested with a typical mix of Sitka Spruce, Western Hemlock, and Western Red Cedar. Spruce is more predominant near the shore, and hemlock and cedar are more abundant inland. The forest understory is generally bare litter with some moss. Grass occurs along shoreline knolls and ridges, and scattered shrubs grow in patches throughout the island. Most of the shoreline of the island is rocky and cliff-bound. The islets range from bare rock, or rock with patches of grass and forbes, to forested islets with an understory varying from grasses to patchy or continuous dense shrubs. Gordon Islands, to the east of Anthony Island, are a series of rugged, dissected rocky knolls, covered with dense salal under a sparse spruce forest. Flatrock Island, Adam Rocks, and Louscoone Rocks are rocky with patches of grasses and forbes.
Other species of seabirds nesting on these islands include Pelagic Cormorants, Ancient Murrelets, Tufted Puffins and Horned Puffins (fewer than 25 pairs of Horned Puffins are suspected of nesting in Canada). Peregrine Falcons (ssp. pealei) are recorded in the area and Bald Eagles nest on the Anthony Island complex and Gordon Islands.
Primary threats to the area are from potential oil spills, and possible disturbance from boaters and other visitors. The spread of introduced predators (raccoons), which are found on nearby Moresby Island, is a potential threat.
