Nuke Poison Ivy (PI)? That may be a slight over-reaction. What surprises me is that PI (Toxicodendron radicans) is included in the Atlantic Coastal Plain Flora, as per the N.S. Nature Trust's "Guide to the Atlantic Coastal Plain Flora of Nova Scotia" (2005), in spite of its wide range in Eastern Canada and U.S. Could someone comment? I continue to be surprised by how many outdoorsy people cannot identify it in the field, in spite of having spent years in the out of doors. In a recent medical article I've read that 80 % of the population is allergic to the above species. Sadly, there was no indication of the source of this tidbit of information. Which population? I suspect that the percentage refers to the fraction of the population who become allergic following repeated physical contact with the plant. Dusan Soudek
