[MAIPC] MAIPC Digest, Vol 146, Issue 1

[Susan McLaughlin]

Although Joe's message was not originally posted to this listserve, I am
hoping that the conversation will continue here or that we will be given a
summary.  In reviewing invasive plant sources, it does appear that orchard
grass is quite a spreader and considered invasive by some authorities.  I
know little about its impact, however.

Given how inconsistent listings are across the mid-Atlantic, more
discussions about the decisions made re invasiveness and regulatory action
would be helpful, in my opinion.

Many thanks.
