The Trincomali Nature Sanctuary protects 12 ha of coastal bluffs towering over the Trincomali Channel, and a second-growth coastal Douglas-fir forest which provides a natural buffer to nearby wetlands. These cliffs are home to nesting double-crested and pelagic cormorants, including one of the most successful colonies in the Strait of Georgia. Cormorants, glaucous-winged gulls, and pigeon guillemots choose steep rock faces for their nests to protect their young from bald eagles.
The Islands Trust Conservancy acquired the property in 2001, in partnership with the Habitat Acquisition Trust and The Land Conservancy. The Galiano Conservancy helps to maintain the rare Garry Oak ecosystem at the crest of the coastal cliffs by removing introduced Scotch broom from steep areas.
