It is possible that the tallest tree of the world up to the end of the 19th century was coast Douglas fir – in 1897 there was cut reportedly 142 m tall fir in Loup’s Ranch, Washington state (4). Nowadays the tallest known coast Douglas fir is Doerner Fir in Oregon, 99.76 m tall. The age of this tree is approximately 450 – 500 years.

This giant tree was discovered in 1989 by Hank Wiliams and first measured two years later. It has been measured several times with slightly different results from 99.4 to 100.3 m. The result which exceeded 100 m mark, was measured when the tree was a bit taller and its top was still there.

One of more recent measurements was done in 2008 by three climbers (Brian French, Will Koomjian, Sean O’Connor) from Ascending the Giants of Portland – they climbed the tree up to the top and measured it with tape – it was 99.7 m tall. In 2011 there was made one more measurement – the result was 99.75 m (3). The tree stands on a slope and there has been calculated the average level at its base.

The upper 15 m of this giant tree are almost dead. Due to this Doerner Fir step by step decreases in height, but it is expected that the circumference and volume of timber will gradually increase.

In the tree have been spotted clouded salamanders (Aneides ferreus) – rare amphibians which seem to be living in trees.

Initially the tree was named Brummit Fir – after the stream near it. Later though it got the name of Ray Doerner, Douglas County Commissioner.

Bureau of Land Management has arranged a special Doerner Fir Trail, leading through a primeval forest (called also cathedral forests) of Oregon’s Coast Ranges.

There is a probability that in remote valleys of Oregon might be found a taller coast Douglas fir.

Doerner Fir is included in the following list:

Category includes some of the most impressive and interesting separate trees of the the world. Total number of tree species in the world still is a wild guess – may be 10,000 and may be 100,000 but most likely somewhere in between. Every month there are reported new tree species from the whole world, including the Western Europe.
