How do we figure or take into account native species like Kiswara,
Eucalyptus,  Tola (which is a bush, would that be wood?)

and here is where the walking gets "thicker" - animal dung, which is
relative to what they are grazing on and maybe climate.  Species like
Yareta, which I think is like a liechen, but I've been told it is a tree
