Eyes on hawkweed Meadow hawkweed is a big problem in Idaho.
Orange hawkweed is more troublesome in western Montana.
To find a biological solution for those and other hawkweed species, Jeff Littlefield is working with a research consortium based in Idaho. He is conducting tests to see if gall wasps might help control the noxious weed that covers approximately 56,000 acres in Montana. Hawkweeds tend to form dense mats that crowd out native vegetation. The plants then send up flowering stems. Meadow hawkweeds have yellow flowers.
