Endangered Wild Plants of N.S. (Click on link)
This article by Paul Keddy in the June 1978 issue of DNR's CONSERVATION publication is still timely. Paul addresses the questions, "What are they [rare and endangered species]? Where do they grow? What can be done to protect them?" Paul's distribution map for the three less common floras which host most of our species at risk is shown below. (The map was unforunately deleted in the most recent posting of this article.)
