Just a few observations. Don and I have a real challenge on our hands with respect to the single versus multi-stem debate in the AF MGWG. So, we keep exploring the subject from fresh outlooks. We're not wavering on our personal positions, but we don't want to get surprised by arguments that we haven't considered. Until recently, some aspects were clear in my mind. For example, your position on what is a multi-stemmed tree that began from a single seed versus separate trees that fused is bolstered by years of experience as an arborist. This has been enough for me. But I presume the same can be said about the experience of Mario Vaden. As I read each of your posts, it seems that you reach different conclusions on what can be consider a single tree for conifers that split into two or more trunks at near ground level. I am hoping other arborists, foresters, horticulturists, etc. who observe tree structures will voice their opinions. Can any of these white pines that I am calling doubles actually be from one seed? My current conclusion is probably not, but Mario Vaden's posts have made me less confident.
My personal position is that the pith test is generally sufficient to identify doubles, triples, etc. in conifers most of the time. I can easily recognize a hardwood coppice, as can the rest of you, but for species like silver maple, I'm not always sure if I'm looking at two or more trees that began from separate seeds or a coppice that developed from a single root structure. In the case of the National Register, I would absolutely exclude the former from the competition, but would probably try to find a place for the latter. I prefer separate listings, but I'm not sure that I'll get my way.
