I've been taking advantage of the warm interlude that is falling after the tick season and before leaf fall is complete to census and map the trees on our property here. I've gotten all of the lowland (mostly open) and about a third of the forested upland done, tallying all trees with a DBH (diameter at breast height) > 10 cm. Tallied 1070 trees so far. Here's a brief summary. If it's not formatted in a nice table it's because someone has compressed all the spaces...

Carya "ovalis" isn't considered a separate species from C. glabra by most people anymore, but it is a fairly distinct form. Conversely, the hackberries are considered to be two species, but the ones here seem to grade continuously between the two. And the two elms, well, I've just not sorted them out yet.
