Pacific Northwest Native Plants Resources

BC Big Tree Registry
This is really not particularly concerned with native trees, but I can't figure out where else to put it. The purpose of the registry is to identify, describe, monitor and conserve the largest trees of each species within British Columbia, and to educate and enlist the help of its citizens in this task. You can search or browse by a few different criteria. There are photos where ones have been submitted, and a map.
