Four years ago we hired a professional botanist to facilitate restoration of riparian and prairie habitat on two farms. Since then the projects have grown to encompass more than 200 acres of prairie, oak, and riparian habitat. These restoration projects are in partnership with a variety of State and Federal agencies as well as non-profit and volunteer groups. Early on, we recognized our need and the need of others doing similar work to have a reliable supply of a wide-range of source-identified native Willamette Valley seed and plants. Since 2001, we have propagated over 100 species of native grasses, sedges, rushes and wildflowers. In addition, we are propagating, under permit, seven threatened and endangered plant species for reintroduction to our restoration sites and for sale to government agencies and non-profits. Over 95% of the Willamette Valley is in private ownership. As evidenced by our own restoration efforts, the
key to restoring these habitats within the valley is to forge partnerships with a variety of stake holders.
There are two very important publications that help guide landowners hoping to restore these important habitats:
Many native grasses and wildflower species are slow to establish from seed. Proper site preparation is imperative for successful restoration using native seed or plants. The factor most limiting the success of native seed establishment and plant persistence is competition from exotic weeds. Restoration professionals use a variety of methods to reduce the amount of weeds and weed seed present on a site before native seed introduction. These methods include: tilling, burning, mowing, soil solarization, and various herbicide treatments. Whatever methods are implemented, it is important to note that soil disturbance following site preparation will bring new weed seeds to the surface. This diminishes the success of any seeding or planting efforts. Our staff biologist, Lynda Boyer, has prepared a document "Native Willamette Valley Oak Habitat and Prairie Restoration Site-Preparation and Seeding Information" that contains information obtained during our own restoration journey as well as a list of restoration resources provided by others.
