All, Regarding Phragmites -- Having resided in eastern Ontario for decades and having also seen what invasive Phragmites has done to wetlands in Ontario and Quebec, I think Fred's warnings are well worth heeding. Fred has been closely monitoring the spread of Phragmites for decades and probably knows more about it than just about anyone else in eastern Canada. Even based on my own casual observations, I know that, where once there were patches that could be measured in meters, many of those "patches" must now be measured in hectares of an impenetrable monoculture mass. Along freeways, it is measured not in meters but kilometres. I'm on the Field Botanists of Ontario Facebook group where Fred has also posted about the Phragmites survey and I can attest to the fact that in the comments, no one is saying "ignore it" or "live with it". Virtually everyone is talking *eradication* because we've all seen at least a few wetland areas in our regions completely destroyed by Phragmites as it chokes ditches and dries up wetland habitat. As mentioned in the article I've linked at the end of this post, the rhizomes are meters long with new shoots sprouting up along them. They also secrete soil toxins that destroy other plants -- see this link: https://www.sciencedaily.com/releases/2007/10/071012084128.htm Now, I've only lived in the Annapolis Royal area a few years, but in this time, the "little patch" of Phragmites that I first saw in the late 1990s is now all over the place in the vicinity of the French Basic wetland trail. Again, something that once could have been measured in meters is now approaching the "measured in hectares" stage. Unfortunately, I don't think there has been much effort to try to do anything about it. I've asked around a bit and it seems like everyone knows it is a growing problem, but all are at a loss about what to do about it. Anyhow, here's a pretty good article on Phragmites, its impact on wetland habitat, farmland, etc.. and also on eradication efforts being attempted in Ontario: https://tvo.org/article/current-affairs/climate-watch/phragmites-are-ontarios-worst-invasive-plants--but-the-phragbusters-are-on-the-case Bev Wigney Round Hill, NS On 11/25/17, David <dwebster@glinx.com> wrote: > Hi Fred & All, > Before the 101 series Highways were built, Phragmites was local and > uncommon in NS.
