Koslany, I live in NE also, have acres of woods I wander and many old apple trees, poplar, alder and birch (and very little black walnut or oak, but of course much maple). You use apple, poplar, birch, or alder? I may scout for some that I can use in future tanks. Was considering doing the same for suitable small rocks for hardscaping, because paying for dragon stone seems a bit crazy. Of course I'd want something completely inert. Maybe rotting of wood is a concern, as JJ09 notes?
I also am not up on any of those you mention but I do have some "ideas" that seem to apply to most wood. I'm one who looks more at each item as it is found, rather than trying to sort out what it might have been, before nature took over.
There seems to be a bit of more likely that a wood will degrade sooner if it is one that grows really quickly. I feel (more than know?) that the space left between the layers is part of the speed of decay as those spaces are often mostly just sap/moisture, etc. and when that is gone as it dries, it leaves space which is smaller in slower growing trees like many of the hardwoods we speak of so often. Without ever having used it, I might lean toward maple as being the best bet of those you mention.
But, in every case, I do look for the really dry stuff, more than species. I find my best places are around lakes which rise and fall or rivers, where things get tossed up in piles and laid out to dry without being down on the ground where so much of the bugs, mold, and rot get to the wood. If you go hiking and know the woods, you may know a spot if you think about it, but one way I sort places when traveling is to use Google Maps to look for piles of wood. Prevailing winds tend to pile it on the North and East points of lakes, so I bore in on those first and then sort out some spots which I can drive to somewhat close to avoid the ten mile hike with a 20 pound hunk of wood!
Happy hunting as it's good fun, even if you don't find the Great ONE!
