Interesting article from 538: What Happens When Humans Fall In Love With An Invasive Species
Shikha Singh posted a topic in Community News
Hello Everyone! Hope you all are doing well. I just wanted to pass on a relevant link that I found entitled "What Happens When Humans Fall In Love With An Invasive Species". Be it mute swans, japanese knotweed or something else, the human dimensions of this issue is really interesting. There are some interesting nuggets of information that may apply directly or indirectly to some of the issues various CISMA's are dealing with. https://fivethirtyeight.com/features/what-happens-when-humans-fall-in-love-with-an-invasive-species/?ex_cid=story-facebook&fbclid=IwAR1NqAv4kdIu-ka5JEUUFLWYKtYB8yZwLEb9J3bwx3dkihBOoba8VWuJHFk Please let me know if this is an appropriate venue for sharing these articles. If not, I can just email interested parties. Sincerely, Shikha -

Request for information/experience - small carpetgrass (Arthraxon hispidus)
Shaun Howard posted a topic in Best Management Practices (BMP) and Treatment
A colleague in southern Ohio reached out to the TNC invasives/stewardship email lists with questions about small carpetgrass control. His message is as follows: I work in southern Ohio and like many places, we’ve had an unusually wet year. This has apparently contributed to an explosion of small carpetgrass (Arthraxon hispidus) in some of our managed grasslands. We’ve been mowing monocultures of Canada goldenrod (Solidago canadensis) and Chinese lespedeza (Sercicea lespedeza) before seed set in some areas and apparently by reducing the prevalence of these plants we inadvertently made a great seed bed for the carpetgrass (see photos). Does anyone have any idea on how to combat this plant at scales in the tens of acres at once? I’ve heard about using grass specific herbicide. We’ve had some success with small scale applications in planted informational prairies and near facilities, but are just now testing out larger acreage applications. Waiting to see how the larger application goes, but until then I’m still a bit hesitant to really drop it on large acreages (we’re using Fusilade II). We’re also just trying to mow it similar to the lespedeza control, which can also be seen in the picture, although some of those mowed plants have already flowered again. We’re concerned that the prevalence of this plant off TNC property and in much of the roadways around the preserve will just continue the cycle of “kill what’s there -> great seedbed for carpetgrasses not in the managed area -> kill what’s there -> etc. etc.”. Devil’s advocate question: has the abundance of this plant had tangible negative effects on grassland birds or other grassland specific species in your area? I.E. can we accept that every fall this plant will dominate, but the spring/summer months are “business as usual” for the grasslands? Thanks for any insight - Michael P. Hall - Southern Ohio Stewardship Coordinator So, anyone have experience with this? Ryan Wheeler noted that it co-occurs with Japanese stiltgrass, so I feel this one could be an up-and-coming issue for all of us, especially those managing prairies/grasslands. -

Japanese knotweed knowledge and eradication help needed

If you wanted to try a chemical free approach, I can share how I am managing it. But it is a work in progress, so no conclusive results...yet. -
Japanese knotweed knowledge and eradication help needed
Claire Peterson replied to Emberdrake's topic in Terrestrial Invasive Species
You're welcome! If you need additional help, please go to our main website http://www.michiganinvasives.org/ and find your local cooperative invasive species management area. They would be more than happy to provide you with additional information and help if possible. -

Japanese knotweed knowledge and eradication help needed
Emberdrake posted a topic in Terrestrial Invasive Species
Hello im new here but am looking for help to eradicate a stand of japanese knotwood. Ive already dug it all out once and it stayed manageable till this year. I did not know what it was when i pulled it out on 2013 but i do now and need it gone. Everything ive been pulling since i discovered what it is, has been burned. -
boot brush station recommendations and signage
Katie Grzesiak replied to Sigrid Resh's topic in Terrestrial Invasive Species
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! -

boot brush station recommendations and signage
Sigrid Resh posted a topic in Terrestrial Invasive Species
Hi All, I have a partner who wants to put up a boot brush station, and I'm wondering if there is any recommendations for purchasing pre-built stations, or designs for making them. Also, are there any signs that people have already made that KISMA could modify and use for the boot brush area? Thank you in advance for time and thoughts. Hope everybody's summer is going well. Cheers, Sigrid -
Hogweed or Not?

Many thanks, Ryan! Those smaller details I'm really unfamiliar with, so your response really helped! -
Hogweed or Not?
Ryan Koziatek replied to Elise Desjarlais's topic in What is it? Species Identification Help
I would also agree with cow parsnip. For me the indicators were the color of the stem (not mottled purple), the small size of the leaves, there are less than 50 rays on the primary umbel, the obcordate seed, and that most of the oil tubes on most of the seeds are at around 1/2 the length of the seed rather than >3/4 of the length. -
Hogweed or Not?
Elise Desjarlais replied to Elise Desjarlais's topic in What is it? Species Identification Help
Thanks, Katie! I've also been leaning towards really intense cow-parsnip, but I keep second guessing myself on this one! -
Hogweed or Not?
Katie Grzesiak replied to Elise Desjarlais's topic in What is it? Species Identification Help
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. -
Hi all, I was recently called out to a site in our CISMA that was ID'd by the caller as giant hogweed. This far into the season, I've really started to sift out what is mis-identified cow parsnip, and what might actually be a valid sighting of hogweed. Getting to the site, I'm having a really difficult time deciding, so I figured I'd post my pictures here for some input. The only in-person viewing I've had of hogweed was at last year's CISMA field trip near Grand Haven, and from my pictures as well as online comparisons I'm still having difficulties! Its not helping the plant is on its way out for the season, so input would be greatly appreciated. Thanks all! For reference: the plants are topping out at 4' tall, seedheads were 9" across at best. Not sure if hogweed can grow smaller than usually reported? The hairy stems and matching seeds are stumping me.
