Site description Englefield Bay is situated on the northwest coast of Moresby Island, at the mouths of Moore and Inskip channels. Two clusters of islands within the bay support nesting seabirds: to the north, Saunders, Helgesen, Willie, Carswell, Lihou islands and Bone Point; and to the south, Luxmoore and Rogers islands, Moresby Islets, and Cape Kuper. These islands support the only major nesting concentration of seabirds along this section of rugged coastline.

The larger islands are forested with a mix of sitka spruce, western hemlock and western red cedar. The smaller islands support spruce and some hemlock, with more extensive areas of forbes and grasses than the larger islands. The three largest islands in the group, Helgesen (54 ha), Lihou (75 ha) and Saunders (55 ha) are rugged and precipitous, bound by cliffs and deeply dissected by gorges and crevices that effectively divide the islands into segments.
