The Institute for Applied Ecology (IAE) is collaborating with Oregon Department of Transportation (ODOT) to restore their 20 acre Witham-Gellatly property near Philomath.
Restoration at the upland prairie will mitigate for incidental impacts to Kincaid’s lupine (Lupinus oreganus) and Fender’s blue butterfly (Icaricia icarioides fenderi) during routine road maintenance activities, as outlined in ODOT’s Statewide Habitat Conservation Plan.
Witham-Gellatly was intensively grazed by cattle for many years and was dominated by non-native annual grasses and weedy flowering plants. However, there are small remnant patches of the threatened Kincaid’s lupine, as well as a few other native forbs.
Seventeen species of native forbs, including toughleaf iris (Iris tenax), dwarf checkerbloom (Sidalcea virgata), and grand collomia (Collomia grandiflora), were included in the mix, along with Roemer’s fescue (Festuca roemeri) and a few sedges and rushes. Follow-up seeding in 2016 will establish more forbs and other native grasses. Seed for the project came from nurseries such as Heritage Seedlings, Pacific Northwest Natives and the Corvallis Plant Materials Center (Natural Resources Conservation Service).
Ultimately, we hope that Fender’s blue butterfly will be attracted to Witham-Gellatly by the presence of Kincaid’s lupine, their primary larval host plant, as well as an abundance of nectar-producing plants.
