[APWG] Mustard invades bare areas, needs native plants to control it

[Wayne Tyson]

Honorable Forum:

Dremman's facts are basically correct, and I tend to agree with his general 
conclusions. I am particularly in tune with his focus on the Big Picture. I 
might quibble with some of his more dramatic expressions, but not at this 
level of detail.
