I live in Vancouver Canada, my house was built in the 1950’s and the basement has the floor joists of the kitchen [above it] exposed.
At that time forestry here was felling massive ancient trees. I’m curious how precisely I can establish a maximum age of the trees felled.
Obviously I could count the rings visible on the joists and subtract that number from 1950, but not having the tree’s full diameter limits measurement. I understand it’s possible to compare relative ring sizes with existing [cross referenced] data sets to date timber.
Does anyone have any experience doing this or able to point me in the right direction? Any resources I’m unlikely to find on Google?
The first step, in my opinion, is to find any existing local-ish datasets. I reckon that around you, there could be trees that go back well over 1000 years to use as a reference. You could then try to find the oldest ring of the wood in your house. It’s probably pretty hard to count back before that, but you could try to make estimates based on the circular ark of the grain pattern to determine a trunk diameter.
