The western red-cedar is a tree that continues to surpass the others. Not only is it the largest tree in the Pacific Northwest, it is also one of the longest lived tree species in western Washington. Some western red-cedars have been recorded to reach 1,500 years of age. (The tree’s name is spelled either red-cedar or redcedar to indicate that it is not a “true” cedar, which grows only in Mediterranean regions.)
The age of a western red-cedar can be roughly estimated by looking at the tree’s crown. For the first several centuries, the top of the red-cedar has a relatively simple crown. However, with age, the crown form changes and candelabra tops – which are often seen in ancient trees – begin to emerge. (See drawing).

Both guidebooks are free to download.
