Kiidk'yaas, Sacred tree in North Coast Regional District, Canada

Kiidk'yaas was a Sitka spruce (Picea sitchensis 'Aurea') that grew on the bank of the Yakoun River on Haida Gwaii, about six kilometres south of Port Clements, British Columbia. A rare genetic mutation made its needles golden instead of green. The tree was felled in January 1997.

In January 1997, forest engineer Grant Hadwin cut down this roughly 300-year-old tree to protest logging practices in British Columbia. The incident sparked nationwide discussions about conservation and forestry management.

The Haida name Kiidk'yaas means "ancient tree" in the Haida language. In Haida mythology, a boy who disobeyed his grandfather during a storm was turned into the golden spruce where he stood. The tree was considered sacred by the Haida people.

The University of British Columbia keeps a sapling grown from cuttings taken in 1977 from the original tree and now used for research. Visitors can view the young tree on campus, where it continues to produce golden needles.

After the felling, part of the wood was used to craft Six String Nation, a guitar incorporating materials from across Canada. The instrument travels the country and is played at concerts to represent community and cultural diversity.
