Thanks for putting up these links, Pyrites. I'm going to enjoy reading all the details in the PLOS ONE research paper referenced in the current CBC article.
At first it seemed like "old news" since I have a 2006 book on the subject by Judith Williams in my library. Seems like what's new is that the researchers have begun to figure out how old the clam gardens are. You commented,
Itís hard to imagine needing to increase natural production of clams in Puget Sound.
We've always assumed that the coast natives were much more nomadic than they actually were, and unsophisticated (compared to us). These gardens would have enabled them to make substantial increase within each tribe's territory, and made their harvesting sustainable. What's intriguing is the possibility of how much we don't have access to because of changing sea levels. I seem to recall reading that there was once a land bridge between Haida Gwaii and the mainland (or a much smaller, shallower channel).
Given that tribes here in Washington extensively burned to clear land for huckleberries in the mountains, and burned to keep Sequim prairie open for deer and elk... yeah, there's probably a lot we've missed along the way.
Example: Wouldn't surprise me at all that we're running into camas in places that it was introduced and somehow encouraged.
