Subject: pesticides and bryophytes

I am the Forest Service Region 8 pesticide use coordinator and while
teaching recently hit a subject area for which I had no information.
John Taylor recommended you as a source or at least a beginning point in
trying to run it down.=20

Specifically I was asked what the effects of aquatic (or terrestrial)
labeled herbicides were on nonvascular plants such as mosses, sphagnum.
Are you familiar with any research into non-target effects of herbicide
use on bryophytes and other nonvascular plants?? If you aren't familiar
with this the effects on this group (these groups) of plants do you know
where I might go next with this question?=20

Thanks!
