I was thinking the other day about what my preferred species for firewood would be, based on my burning habits, climate, etc. My conclusion was that Douglas Fir and Big Leaf Maple have ideal btus/burn rate for this area. They also happen to be very abundant native trees to this area. Now, as a scrounger, I get all kinds of wood. Native, non-native, softwood, hardwood, pretty much the gamut. I dig me some nice dry red or white oak, but usually save it up for the week or two of real winter we get here. It's too dense for daily use most of the time. Our native oaks, however, tend to be lower btus, and less common. My hypothesis is this: were I to burn only native trees as firewood in the ratio they are represented regionally, I would have an ideal mix of firewood for the burning season in this area. Does this hold true where you live, or have I had too many beers?
