Treents should drop wood and kindling

[SteveMaurer]

And probably nothing else.   It makes sense for them.
For Treents protecting sources of wood, they should drop the same type of wood.

Treants are gnarly things, though, and I have to imagine animate wood is different than ordinary tree material.

Kindling, sure.  But I don't know how useful Treant bits would be to a carpenter.
