Site description The Moore and Byers Islands and Banks area lie along the east side of Hecate Strait midway up the mainland coast of British Columbia, between the north end of Vancouver Island and Prince Rupert. The site is approximately 100 kilometres northwest of the town of Bella Bella. The area includes all the islands, islets and reefs within the two clusters that lie from ten to eighteen kilometres off the west coast of Aristazabel Island. The northern and southern clusters of islands are separated by Wright Passage. Also within the site are the marine waters in a ten-kilometre radius around the island chain; this includes the shallow banks around the islands.

In general, these islands are low and gently undulating with a few steep portions along rocky perimeter areas. The shoreline of the large islands are convoluted and thus have many shallow bays and tidal channels. Many of the islands support forests dominated by Sitka Spruce, while the larger islands have grassy and herbaceous cover.
