Thanks for continuing to provide info on this topic. To your point, Swamp Ash is a nickname of sorts. I imagine that alot of the references we are looking at may be wrong in linking the name to various species of ash because so many people don't know what it is. There probably are several species which could be used for Swamp Ash but I think that in practical terms of what is grown, harvested, and sold it is probably one or maybe two species that make up 99% of what is being sold as Swamp Ash. My theory, based on what I have read, is that the dominant species is green ash. Perhaps your supplier could provide info as to what species he is selling to you? I'm not on a witch hunt here by any means. Just having fun trying to figure this mystery out.
