For the second year running, ISN has treated giant hogweed (Heracleum mantegazzianum) in Manistee County. There are only 2 known populations, and with this plants severe human health implications, it's a major Early Detection and Response priority. We're pleased to report that this population was down to just 9 plants (1 adult and 8 juveniles); last year there were nearly 30, and 2 adults!
It's crucial for people to report sightings of all invasive species, but especially Early Detection plants like hogweed. Check out this great ID training module; there are some native look-alikes for this crazy plant.
