The Wetland Plant Cooperative and Native Plant Holding Facility, operated by King Conservation District, demonstrates a unique approach to water conservation and habitat restoration. Located at the King County Wastewater Treatment Facility, the site uses reclaimed water from the treatment process to sustain its inventory of native plants.
With support from SCC's Riparian Plant Propagation Program, the facility was expanded to grow native plants for river and streambank restoration projects. These plants are essential for improving salmon habitat throughout Washington, contributing to healthier aquatic ecosystems.
This innovative initiative highlights the benefits of sustainable water use while advancing critical restoration efforts. It’s a practical and effective solution for conserving water and supporting native fish populations.
With support from the Riparian Plant Propagation Program, large-scale native plant production is underway through a partnership with Puget Sound Plants, enabling the cultivation and statewide distribution of more than 30,000 riparian plants. This high-volume nursery system strengthens Washington’s restoration supply chain and ensures consistent access to locally grown native material.
Grays Harbor Conservation District maintains tens of thousands of native plants annually at a partner-operated holding site, using gravel beds and nursery infrastructure to support healthy plant growth and regional riparian restoration. Through project support and community distribution, the district helps meet evolving restoration needs across the region.
Snohomish Conservation District is expanding its riparian plant capacity while preparing for a new office and greenhouse facility. Through partnerships with Snohomish County, Edmonds College, and the Latino Educational Training Institute, the district maintains thousands of native plants and supports hands-on workforce development for local restoration efforts.
