[APWG] Ecosystem Restoration Data aquisition Cover Relevance Re: Mathematical Constants for plants and soil, plus Deep Weeding

[Wayne Tyson]

Dear Craig and all:

There's a lot to "cover" here, so I'm breaking up my questions into 
byte-sized pieces in the hopes that I will be able to comprehend each 
element, then "hopefully," the whole.

Let's try to cover cover first. What ecological condition(s) are revealed by 
cover?
