Gwaii Haanas National Park Reserve, National Marine Conservation Area Reserve, and Haida Heritage Site

Pacific temperate rainforest sweeps from sea level up the slopes of the San Christoval Mountains that form the backbone of Gwaii Haanas. At lower elevations, rain and moderate temperatures help to nurture dense, mossy forests of immense western red cedar, western hemlock, and Sitka spruce trees.

The sea around Gwaii Haanas teems with life. These waters are home to salmon, herring, halibut, rockfish, crab, seastar, sea urchin, octopus, and numerous other species.
