    Hogweed or Not?

    Many thanks, Ryan! Those smaller details I'm really unfamiliar with, so your response really helped!

    Hogweed or Not?

    Thanks, Katie! I've also been leaning towards really intense cow-parsnip, but I keep second guessing myself on this one!

    Hogweed or Not?

    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.

    Black Swallowwort Treatment

    Thanks so much, Nor! I'll check into what its been sprayed with, maybe we're just using the wrong chemical for the most effective treatment. I'd definitely like to hear how it looks this year! Hope the treatment was successful!
  5. Hi all! I'm reaching out regarding the treatment of black swallowwort. Its still in the EDRR stages up here in the U.P., and in my CISMA area we only have one known infestation. We've been helping to treat it for multiple years now, but we're wondering if perhaps we're not using some of the best management practices on it. My questions are: 1. If you've treated it, what chemical did you find worked best? Or did you find a non-chemical solution worked well, too? 2. What time of year/phenology of the plant did you treat it? 3. Any other advice? Thanks everyone! Hope you all have a great weekend!
