back to plants.

Some years ago, I recall a paper on how to determine if one should make a
plant collection from a population.  It might have been in Rhodora or Bull.
Torrey Bot Club. Someone had suggested a minimum number of individuals
should be present in a population before it was "safe" to make a
destructive plant collection(whole plant removal).  Anyone remember this OR
have other guidelines from anywhere that might serve in makeing these
decisions.  I usually work on weedy stuff, numbers are not ususally a
problem.  I am trying to advise a colleague.
