<p class=MsoNormal>Dear All,<br>
One statement that is constantly written on this list is, "use the small<br>
limbs from the trees and do not cut the whole tree." This is a false<br>
economy. A tree is a conductor of current, nutrients flow from the soil<br>
up the stem to the top of the tree then the leaves and limbs fall back<br>
down to the ground to be recycled. In this case the tree is not<br>
conducting electricity but nutrients. People need to be able to see this<br>
fundamental process. If you have the capacity to understand this you<br>
will see the reason for selectively harvesting the tree trunks and<br>
leaving the tops and small diameter wood. The nutrients in the tree are<br>
in the branches, bark and leaves, the stem having the least amount. It's<br>
also good to leave the bark in the woodlot. Otherwise, in time, you will<br>
kill off your woodlot. It is not the tree that cleans the air it is the<br>
whole system that cleans the air and if you steal the small diameter<br>
wood your essentially shorting out this system.<br>
<br>
It doesn't matter whether your fuel is wood, grass, weed or crop residue<br>
there still is a common denominator. If you care for the soil the soil<br>
will take care of your biomass.<br>
<br>
<br>
