  1. It's in a weird grey zone for us. It's technically an EDR species in our region, but it also seems to be growing exclusively in road ROWs and not spreading into higher-quality areas. We're encouraging removal. We were hoping to have a better handle on our actions this year... but it's 2020.
  2. I've had lots of questions about this plant this year for the first time! I don't have any professional experience with it, but personal. My mother planted some as a ground cover in a part-shade spot, and it was aggressive. We worked hard to remove it years later (physical only, dig/pull), and eventually mostly got rid of it, though a sprout or two comes up each year. I haven't seen evidence of it escaping into natural areas--yet. I would expect similar risks regarding compost/dump piles in woods turning into escapees as other, more obviously identified as invasive ground covers. The one thing that may be saving it from being truly invasive is that it seems to be more patchy than truly covering--one of the reasons we ripped it out in the first place. That's only my experience in one location (literally one spot in one yard), so it could be very different overall.
  3. We have some up north, though we haven't worked very hard on it yet. Apparently treatment is similar to garlic mustard: pull before seeds or try glyphosate or triclopyr sprays. Our reports from volunteers are similar to garlic mustard too: thick patches are harder to knock back (and an ebb-and-flow of dense and lighter years), and smaller ones may be "won" in a few years.
  4. The good news is that the seeds are still green and tight in their siliques (those long thin pods)--you can pull! Be sure to bag it and send it to a landfill or tarp a big pile on-site (or other disposal options) so those ripening seeds don't escape. Once the seeds are brown and dry, the siliques will open up when you pull the plants; at that point, it's no longer a good idea to pull the plants because of the risk of spread. Thanks for your sharp eyes and dedication to habitat!
  5. Hmmm, unfortunately, nothing is springing to mind. @DGregori, would you be able to post a photo a little later in the year? Flowers or additional leaves may be of use. Your local MSU Extension office may be able to help too!
  6. I'm sure we're all creating lots of outreach stuff or ideas for how to reach people while we can't hang out with them, and wanted to share some of what ISN's cooking up. Please share yours too! Coloring pages: https://www.habitatmatters.org/education.html--I know others are doing this too! Let's share! Video work (in progress), particularly about decontamination and species ID We're going to have a mini-garlic mustard challenge in our service area, probably? Our spring partner meeting will be held online via Zoom Outreach to swap groups and other local groups on Facebook etc. regarding invasive species (thanks for the idea from Renee Penny of Kalkaska CD/CAKE CISMA) Probably other things I'm forgetting!
  7. ISN is hoping to work more with TOH for exactly this reason--our updated prioritization is still in the works, but (spoilers!), TOH has moved up to a higher priority for us. Funding-depending, we're hoping to work with growers of all kinds (especially in an area like ours with lots of fruit trees). I like the idea of the wineries/breweries too! The biggest challenge we see is actually killing the tree. Literature suggests frill-cuts (instead of cut-stump) is the best treatment, and a lot of the trees we know of in our region are close to structures. Combine that with TOH's already brittle wood, and that could be a yucky situation! We're hoping to partner with and/or train some arborists on treatments.
  8. ISN has used beetles in multiple projects since 2012, and it's gone really well. Obviously, the beetles don't eradicate loosestrife, so follow-up releases are required after 5 or so years, but it's made marked impacts on large populations (not small/medium ones). There is a fair amount of communication that needs to happen with the public--the beetles take a year or two to get established, and it's not eradication! But dang if they don't help keep things to a dull roar in a nice rollercoaster of population sizes. ISN has ordered ours through Wildlife and Wetlands Solutions for a very reasonable price (something like $150 for a pot with over 1,000 beetles), but I'm sure there are other sources as well!
  9. ISN staff are required to have have Core (obviously), Right-of-Way (catchall), Aquatic (Phragmites etc.), and Ornamental (sometimes we treat on private properties in ornamental settings, especially with knotweeds), because that covers about all the work we do. A few staff members also have Forest Pest, mainly because they want to; it may come in handy at some point! We picked these certs because they seem to fit what we do the best, but also because Core & Right-of-Way were handed down to us by predecessors as the ones we should have. If they had a "miscellaneous invasive plants" category instead, that would be great.
  10. We have smatterings of it up here, but haven't dealt with it much. I'd assume it would respond well to cut-stump, similar to its cousin burning-bush.
  11. There are a few variegated phrag stands out there, but this specimen is reed canary grass's horrible alter-ego, ribbon grass https://www.habitatmatters.org/reed-canary-grass.html You can ID reed canary grass regardless of coloration from the looooong, papery, clasping ligules coming up from where the blade meets the stem.
  12. Legit started laughing at this one--I never would've expected Persicaria to be a mis-ID either, but WOW it sure is! Thanks for the heads-up.
  13. We've only seen it in ROWs, but it is sometimes in wet areas, where it could possibly cause harm. I'd be interested if anyone has seen it impacting wetland communities?
