Subject: Re: [BEE-L] How to approach a Masal selection?
Thus, I think we need a better description before we understand what you
see.
More than yards, imagine site conditions.
site One: Mountain : Valdivian Temperate Rain Forest.
site Two: Valley, Gorbea area inside blueberry field (highbush).
site Three: Valley, Vilcun are inside blueberry field (highbush) cooler than
Gorbea
