On my dad's place, we used to seek out ironwood for firewood. We never cut down a live tree, but cleaned up every one that clobbered by another falling tree or died out. He's also got way too many mature basswood trees. I started dropping some smaller ones along my clover plot in a sunlight project about 8 years ago. There are no deer per square mile (it is desolate), and the basswood sprouts would all get cleaned off in the spring by the lone doe that would take up residence in the spring.
Stu, when you say ironwood, are you talking about a smaller trunked tree, rock hard, a finer textured bark, slow growing, sap runs in the spring from cuts, and holds it's leaves longer in the fall?
