BSFS – Tree Ring Lab at University of British Columbia, Vancouver, BC

I have been working on a new method of ring sampling with the Tree Ring Lab at the University of British Columbia!  Western red cedars are notoriously hard to date due to the large amount of heartwood rot they tend to develop with age.  By taking notch samples from post-harvest trees through collaboration with forestry companies we are able to sample these old growth trees in order to estimate their age and the relative size-to-age ratio to estimate the ages of living trees in the region. This gives us a more in-depth image of both the trees themselves, and the changing climates that they have lived through.  Some of the western red cedars that I sampled are looking to be upwards of 1200 years old!  Imaging the history we can learn from them.  Imagine how important it is to protect the remaining old growth forests left in British Columbia.
