The Institute for Applied Ecology (IAE) is a 501(c)(3) nonprofit organization with a mission to conserve native species and habitats through restoration, research, and education. Here, we describe some of our projects working with the Conservation Research Program at IAE. The Conservation Research Program conducts research and montioring of native species and ecosystems in order to determine population trends and effective methods for restoration and management, conducts research on invasive species in order to determine effective control methods, and develops plans for the management and restoration of native ecosystems.

Outplanting Willamette Daisy

Common Name: Willamette daisy or Willamette fleabane
Scientific Name: Erigeron decumbens

Species Listing Staus: Erigeron decumbens is listed by the U.S. Fish and Wildlife Service (USFWS) and Oregon Department of Agriculture (ODA) as an endangered species. It is also considered a Special Status Species by the Bureau of Land Managment (BLM).

Distribution: This endemic species is native to prairies in Oregon's Willamette Valley.  Today, the number of extant populations is numbered at about 40. Approximately half of these populations are protected on public lands.

Identification Tips:  The Willamette daisy is a rosette forming perennial forb.  It can be distinguished from similar species by the three prominent parallel veins which run the length of the leaf.

Interesting Facts: The name, decumbens, was originally designated by the famous botanist explorer, Thomas Nuttall, because the comparatively large flowers' weight pulls its stem toward the ground, making them "decumbent".

Project Description: We outplanted over 1500 Willamette daisy at the William Finley National Wildlife Reserve and Fern Ridge Reservoir in West Eugene.  The objectives of this project are,

1. To evaluate different treatments, such as burning, grazing, mowing, and grass herbicide effects on Willamette daisy populations, and
2. Enhance our understanding of Willamette daisy population demography.

The Willamette daisy is in decline due to habitat loss and fragmentation. One of the effects of this has been low seed viability due to inbreeding depression in small populations. For more information, see the Willamette daisy 2006 Study at

Project Partners:
U.S. Fish and Wildlife Service, including Finley National Wildlife Refuge
U.S. Army Corps of Engineers, Fernridge Natural Area
U.S.D.A. Natural Resources Conservation Services, Plant Materials Center
