Last couple of years I've been slaying basswood saplings as an invasive species. We got plenty of poplar for shoulder season ...Zap I was told to get rid of them while I could cause even fully grown there was no btw's to them. So what's your take?
While their wood BTU value is low (13.8 MBTU/cord - about half of oak) and it may not be a great burning wood, I would not consider American Basswood/Linden (Tilia cordata) an invasive species. It is in fact native to our country. Generally the term invasive kicks in for non-native species which tend to spread into the wild and outcompete natives -- usually they don't have natural predators in their new home to keep their populations in check -- so they can outcompete natives and take over. Like the grey squirrel in Europe, which is taking over and driving the native European Red Squirrel toward extinction.
Anyway, if you are culling out all Basswood due to it's low BTUs for firewood, and because they are taking up space where better burning woods could live (Hickory, Locust, etc.), I completely understand that. That becomes "Invasive" in another sense.
I actually never burned Basswood, but with BTU's that low, it cant be a great wood to burn. I know that it isn't the easiest tree to grow from seed (we grow it on our nursery), which further makes me feel that it can't be invasive. Generally the invasive stuff takes off like a weed from seed.
