Paper Mulberry, Tree of Heaven for firewood?

[dboyd351]

I have a friend with some acreage who has a number of paper mulberry trees along the edge of a field, and he is trying to clear that area to use for storage.
I am trying to get a handle on what paper Mulberry is like for firewood. I have looked on the web and some places say it has 25.8 million BTUs but also say it takes two years to season. Other sources say the wood is very light, which would make me think it does not have very many BTUs..
Is there any rate I'm trying to find out if it's worthwhile to save some for firewood?
The same friend also has a fair amount of tree of heaven in the area he wants to clear.
I have tried looking online for information on tree of Heaven and also find quite a bit of conflicting information.
So if anyone has first-hand experience or more reliable information, I'd love to hear it.
Thanks in advance.

Tree of heaven has a very high moisture content and must be seasoned for several years or creosote build up becomes an issue.
Around here in Oak country, we avoid it.
Plus It STINKS

thank you for that quick response
I have better wood I can get too such as the black Locust I've been cutting on the same property so I'll pass on the tree of heaven, possibly the mulberry too, but I'm waiting for more input on that
Seems like the Mulberry takes a while to dry too

Once dry it's burns like paper, it's basically a garbage tree all around. Chop it down, treat the stump and pray the garbage doesn't come back.

Mulberry is middle of the road firewood that does need time to season. The trees are usually a crooked mess. I hate it because the birds spread the seeds everywhere and it becomes an invasive. I am always cutting it out of the evergreens. If it is large enough it gets split and stacked like the other fw.
