World's Largest Yellow Cedars Are On Vancouver Island

St. RandAlly, previous champion Yellow cedar

When it comes to the world's top six largest Yellow cedars, Vancouver Island is where it is at. Five of the top six are in British Columbia (the other is in the state of Washington). Of those five, at least three are on Vancouver Island.

The current largest commonly known specimen of Yellow cedar (Chamaecyparis nootkatensis) can be found near the small town of Sayward on the north west part of the island. It is in an area of big trees along Cooper Creek, and its name is Admiral Broeren.

The previous champion Yellow Cedar grew for many centuries close by to where today's champion stands. Shortly before the St. RandAlly recreational site was to open, the 2000 year old giant tree fell to the forest floor.

The tree was named after Randall Dayton and Ally Gibson, the forestry engineers that discovered the record breaker in 1993. It fell in 2004.

This fallen Yellow cedar boasted impressive measurements:

• Height 61m (200 ft), 
• Circumference 13.08m (42ft.11in), 
• Diameter 4.16m (13.7ft), 
• Crown Spread 16m (52.5ft), and 
• Stem Volume 175 cubic meters (6,200 cu. ft). 

Note: Champion trees in North America are determined with a point system used by the American Forestry Association that awards 1 point per inch of circumference at breast height, 1 point per foot in height, and 1 point for every 4 feet diameter of the live crown.

Sgt. RandAlly's score in AFA Points was 728.

Admiral Broeren, at 575 points, has more volume (188 cubic meters) than Sgt. RandAlly, but is smaller in height, crown and diameter.

The British Columbia Big Tree Registry lists a Yellow cedar with more AFA points (618) than Admiral Broeren. It is listed as a "recent addition", is not named and no location is recorded. I suspect it is on Vancouver Island somewhere, but at this time I can not confirm that.

The tree is recorded as having the following dimensions which would make it more impressive than Admiral Broeren, and the largest in the world:

• Height  46.40 m (152 ft) 
• Circumference 11.59 m (38 ft)
• Diameter 3.68 m (12 ft), 
• Crown Spread 12.2 m (40 ft), and 
• AFA points 618

Yellow Cedar Facts

• Yellow Cedar grows well in deep moist soils. 
• They usually grow as single trees, but may also occur  in small groves. 
• Can be found alongside western red cedar and western hemlock.
• Their beautiful, rot-resistant wood is highly valued. 
• Given optimum conditions, they can reach monumental proportions.
• Many Yellow Cedars are dying in the northern part of their range - global warming has been fingered as the culprit. 
• Chamaecyparis is derived from the Greek word for the ground cypress, an Old World shrub; nootkatensis refers to Nootka Sound on the west side of Vancouver Island where Yellow cedar was first identified by botanists.

Range of the Yellow cedar

These trees are common in old growth forests on Vancouver Island, but are rarer in the south island and east coast where it is too warm. In the southern part of their range they are found high in the hills where it is cooler, and where snow accumulates in winter.
