Lynn Valley Tree
The Lynn Valley Tree was one of the tallest known Coast Douglas-fir, at a measured height of. It was cut down by the Tremblay Brothers, at Argyle Road in 1902 on the property of Alfred John Nye in Lynn Valley, now part of metropolitan Vancouver, BC. In 1912, Alfred Nye told historian Walter Mackay Draycott that the tree had first drawn his attention because of its vast columnar bole, and that it towered above the neighbouring forest. After it was felled, Nye told Draycott he had measured its length at, with a remaining stump height of where its diameter was across the butt, and the bark was thick. Since that time, in the lower valley where the tree grew, the entire old-growth forest has been logged, including a nearby diameter fir tree that contained 1,280 rings, and another fir tree felled in the same valley that was said to have measured tall.
It was one of the tallest trees ever recorded on the planet, exceeded only by a small number of Australian mountain ash other Douglas firs, and perhaps several historic Coast Redwood. In addition, a giant sequoia known as the Father of the Forest from Calaveras grove reportedly measured after it fell many centuries ago. However, Douglas firs seem to have more routinely reached such heights in the past, with anecdotal reports of to over -tall trees being relatively numerous in old records.
Despite measurements of such size being generally considered unreliable, there is a reliable record of a Douglas fir exceeding in height: the Nooksack Giant was measured at tall with a tape after the tree was cut down in the 19th century.
Both of these heights are close to or, in the latter case, exceed the maximum height a tree can attain as calculated by some theorists, or just within the upper limits according to other theorists. Given widespread reports that trees have been measured after felling as exceeding this maximum height, it lends some credibility to the idea that extremely tall trees growing in especially foggy environments are able to reverse the transpiration stream inside them and maintain adequate water supply to parts of the tree above that height.
There are no known surviving photographs of the Lynn Valley Tree.
