You can download the guide (as a honking big pdf of more than 38 megs, or in eight slightly more manageable chunks) at http://www.for.gov.bc.ca/hfd/pubs/docs/mr/mr091.htm, or go to the same site to find out how to get a hard copy.

When I found this I thought, I bet there’s a database somewhere. And there is. The locations, descriptions, etc. of the trees are included in the Provincial Heritage Register (.pdf).

But sadly, we can’t just go and look at a map of Gabriola and see where modified trees have been reported. As they say on the site,

Archaeological site information is sensitive as releasing this information into the public domain may result in looting and destruction of a site.

Therefore, the Archaeology Branch releases information on a need to know basis…where it can be shown that distribution of the records will benefit the management or conservation of these sites.

Okay, I get that.

Here’s an odd-looking cedar tree in the middle of the Gabriola forest. What has made the bark do that weird bumpy thing? Oh wait, look around the side. (Second photo.) Looks like the bark has been very deliberately cut.

I know about Gabriola’s culturally modified trees, which are trees from which bark was removed for First Nations’ use. Did somebody intend to harvest bark from this cedar tree, but then not complete the job? If so, why?

You know that BC First Nations people used cedar for all sort of things: canoes, housing, masks, clothing, blankets, baskets, totem poles, and probably lots of other purposes as well. The Snuneymuxw (Nanaimo Coast Salish) on Gabriola were no exception. Sometimes they took an entire cedar tree, but other times they just took part of a cedar tree. The evidence of their cedar-harvesting remains in our forests, and you can see it on Gabriola once you know what to look for.

Have you ever come across a cedar tree that’s mostly normal, except that the bark is missing on one section of the tree? Or maybe it looks like there’s a bark-free gouge running way up the tree. You could be looking at a tree that the Snuneymuxw used: they harvested bark from that tree, and now you’re seeing the scar.

These trees are called culturally modified trees, and they’re used by archaeologists to show that an area was inhabited by First Nations people during a certain time frame. The tree can be dated (tree rings, remember?) so it’s possible to tell when the bark was taken, and then see the pattern of growth after that. (This article says that culturally modified trees on the BC coast have been dated back to the year 1137 AD.)

Since I learned about this topic, I have a hard time getting anywhere on this island. I want to walk around every tall cedar I see to check its bark. This means I make tons of side-trips and I’m late for lunch, but I’ve found dozens and dozens of these culturally modified trees. They’re everywhere!

Here are some fascinating diagrams showing what happens to culturally modified trees over time. If you’re interested in culturally modified cedars, read this .pdf file from the David Suzuki Foundation: Sacred Cedar: The Cultural and Archaeological Significance of Culturally Modified Trees. It’s amazing.
