Your posting this morning inspired me to check out our favorite population of horsetail (in this case, Equisetum hyemale), which shows as the dark green upright stems in the centre of the attached image which I photographed a couple of hours ago. About 6 weeks ago Mrs. Equiz liberated this patch of horsetail which was up to then overtopped with invasive, non-native English ivy. While she was focussed on that bit of ecological restoration I was suppressing a patch of unwanted reed canary grass. I recall you saying once that you formerly were involved with distribution of reed canary grass and other species suitable for roadside and disturbed site revegetation. In our case we had reed canary grass where it was not wanted in a municipally-owned urban forest. If you google (King County, reed canary grass) there is a useful PDF file posted by King County, State of Washington. I am indebted to King County for making their best management practices for reed canary grass publicly available, and I think we are having some success in using their suggested suppression method for this aggressive introduced grass.
As to my recent lack of postings on this forum, my interests do not go much beyond our interest in natural area management in an urban forest – that is when I am not keeping a daily eye on the fiat price of physical silver and gold, plus watching for positive or negative news about our main paper holdings (Silver Wheaton, Sandstorm, McEwen, Americas Silver, Endeavour Silver, First Majestic, and First Mining Finance). That’s enough to keep us interested, engaged, and content with life, generally paying little attention to all the other market noise and geopolitical noise around us on the internet. Cheers, and thanks for your many interesting postings. Equiz
