Not sure what kind of old trees are in rain forests and if they form rings like these cedars, but perhaps in the highlands nearby a similar record is kept, and not just for 100 years but 200 or 300 years. Of course, some trees can live over 1000 years, the bristlecone pine can live for 5000 years (so far as we know), but it has a lot of dead branches and side branches that become the main tree, so determining a continuous record from a bristlecone might be tough. But this technique should be directly transferable to any habitat I would think, which would help with climate record proxies. Temperature records are good, but precipitation records are every bit as valuable, as droughts are what really causes civilizations to fail. They also need older trees.
