  1. Hi Shelby, ISN's management is mainly working with Road Commissions to mow when it first starts flowering (now/a week ago) to prevent spreading by seed. That said, in a past life with the Park Service I used the herbicide Plateau (imazapic) to great effect; took a year or two (small patch), but left the grasses alone. It's not aquatic-approved. We use Plateau here at the Boardman River Nature Center to keep spurge out of the gardens, but don't do any larger-scale treatments.
  2. Depends on the size. We've often used loppers, as the stems aren't that big and we may be working with volunteers. However, for the work I think you're describing (lots and lots), I'd suggest something like a brush saw (though a chainsaw would work). Cuts down (hah) on the bending/kneeling and speeds everything up a lot!
  3. We prefer to do manual removal or cut-stump over foliar spray. It works great! We use tricolpyr (Garlon). Very close to 100% (if not 100%) mortality. The only thing you have to look out for is the seedlings, particularly ones that come up in subsequent years.
  4. Manual removal is most effective before it flowers. Asparagus knives (something like this) or other weed forks are really great for getting out the taproot. You can use herbicides too, but get excited about surfactant because it takes a fair amount to penetrate the crazy trichomes/prickles.
  5. I have used glyphosate in the past, but timing is important--it's most effective in early season, before the 2nd year plants bolt. It's easy to target the flowering adults, but that's not very effective--2nd years I've just cut the seed heads to prevent spread.
  6. That's what we do too, except we don't even laminate. They don't look great, but we often don't drive around to get them--when they're on private lands, we often request that the landowner grab them after a week or so. For larger projects, we have "yard signs" that are up during our treatment, and sometimes we leave them up longer. We definitely got back for those, if we leave them up. They don't contain the legal treatment information (we also post those signs), just a general "invasive species management happening, and ISN is doing it" sort of thing to help answer questions about why plants are dying. We'd love to hear if people have thought of better ways!
  7. We worked with her last year--she's very knowledgeable and communicates well (and factually!) about the science of invasive species, but really grabs people with her art! A joy to work with.
  8. We leave all Phragmites where it is. In some cases we mow, but the bits are left where they lie (and then we clean machinery!). As you said, the complications (permitting? vectors, etc.) are too great for anything else. Curious what others are up to! Any creative solutions?
  9. Thanks to John & Shaun for the information! Here are a few more notes I took during our session: Let police know what the crew is up to (especially if they're doing driving surveys that might elicit calls!) Name badges/shirts/hats can also help ID your crew as professionals Be clear with your crew about your CISMA's expectations (herbicide use, professionalism, etc.) Be sure to have decontamination kits both for the truck and each person Be sure to have water for washing--one huge reservoir or several jugs (planned use inspections & pesticide business checklists from MDARD, above) Herbicide manufacturers and contractors can be good resources for what herbicides to use Importance of communicating with the public during activities (signs, well-trained crew) Some questions about permitting can be directed to https://www.michigan.gov/deq/0,4561,7-135-3313_3681_3710---,00.html And a possible future action item: Discussion of WM CISMA's treatment table--maybe a subcommittee?
  10. In an effort to not re-create the wheel, here are some of the discussions & resources ISN created during our 2018/19 HWA Prioritization meeting with partners. Feel free to use if it suits you!

  11. This is where the multitude of handouts from the 2018 MISC Annual Meeting treatment discussion/brainstorming session live! Herbicide Information chart, courtesy WM CISMA Strike team costs estimation worksheet, courtesy WM CISMA Strike team startup needs checklist, courtesy WM CISMA Knotweed treatment comparison chart (+ sprayer calibration), courtesy SWxSW CISMA Mix table example, courtesy ISN Emergency Contacts, courtesy ISN End-of-week Checklist, courtesy ISN Treatment Tracking template, courtesy ISN "Truck box" list, courtesy ISN Pesticide training agenda, courtesy ISN Plus, don't forget about the Best Management Practices (BMPs) that MNFI has put together--there are links on michigan.gov/invasives as well as pinned on this Forum. They help with herbicide selection (or other methods). Finally, the manuals for Pesticide Certification are excellent resources--use them! Please comment on this thread with additional resources.

  12. We have always purchased bootbrush station hardware as a kit; we've only found them through EnviroSigns and Best Exhibits, but I encourage you to keep searching (and let us know if you find someone else)! We've purchased them in some bulk (30-40) to keep costs low. If you only need one station, it might be worth making your own, but we've really appreciated the ready-to-assemble nature of the kits. I'm attaching our how-to-install document (from the Downloads section) to give you an idea of what all goes into a station--the kits just include the metal bits, hardware and/or sign, and we've purchased the lumber, gravel, etc. separately, though there may be more complete kits out there. As for the sign itself, ISN made one that could be re-branded pretty easily with a 6x2" logo (or logos) in the upper left corner. It's also available in Downloads. I believe PlayCleanGo also has a sign you could use and/or modify if KISMA is a partner. Our total costs (sign printing, kit purchase, misc. supplies purchase) per station has been between $300 and $400, depending on how many we order; if only one is ordered, costs are likely to be significantly higher. Good luck!
  13. WOW This one is close! But... I'm going with cow parsnip. Hogweed certainly CAN be shorter than 7 ft, but it's usually pretty darn gigantic, and this just seems "pretty big." Check out this link for more specific info: https://www.dec.ny.gov/animals/72766.html You have some pretty indeterminate seeds, but I'd say overall they seem not-flat and heart-shaped. Leaves can be tricky, but those just don't seem quite ridiculous-looking enough. Interested in other opinions, though! It's definitely one of the trickiest I've seen.
  14. Native! This is horsetail (Equisetum), probably field horsetail (E. arvense). No worries about it being invasive, but it's definitely aggressive--and controlling it is pretty darn difficult, as it doesn't respond to most herbicides and grows like crazy. They're likely better off figuring out how to garden WITH it than against it.
  15. Looks like wild parsnip to me. Tell them to be cautious & rinse off; it can cause chemical burns!
