Abstract
Coastal dunes protect urban infrastructure and provide critical habitat for rare and endangered species. Coastal dunes are threatened by development, climate change, and invasive species. They require active restoration activities including seeding and planting to maintain the ecosystem services they provide. Propagation protocols are lacking for most coastal dune species, limiting their successful use in restoration projects. We propagated several coastal dune species native to the west coast of North America from seeds, cuttings, and divisions, in an urban greenhouse in Portland, Oregon using standard greenhouse and nursery techniques. We recorded propagation success and plant development through production in 48-cell plug liners and 4-inch pots to develop a timeline of plant production and photographed the process over time. The majority of plants tested were easily propagated using standard greenhouse and nursery techniques and were ready for planting within one growing season. Some species were not easily propagated and may require specialized cultivation techniques. Plants grown during this project were distributed to partners for use in restoration projects and photographs were provided to OregonFlora and are available for public view.
