Pseudotsuga Menziesii - Largest Trees

Largest Trees

• The tallest tree in the United Kingdom is a Coast Douglas-fir. The tree, growing in Reelig Glen by Inverness is called Dughall Mor and stands at 64 m. It was measured in 2005 by Tony Kirkham and Jon Hammerton from the Royal Botanic Gardens, Kew, the late Jim Paterson from The Tree Register and David Jardine of the Forestry Commission.

• A tree cut down in 1902 at Lynn Valley on the north shore of the city of Vancouver, British Columbia was reported to have measured 415 feet (126 m) in height, and 14 feet 3 in. (4.3 m) in diameter.

• A Douglas-fir felled in 1897 at Loop's Ranch in Whatcom County, Washington reportedly measured 465 feet (142 m) in height, 34 feet (10 m) in circumference at the butt, and 220 feet (67 m) to the first branch. With a volume of 96,345 marketable board feet (227 m3), this tree was estimated to be 480 years old.

• New research suggests Douglas-fir could grow to a maximum height of between 430 feet (130 m) and 476 feet (145 m) at which point water supply would fail.
