Seed Collection and Outplanting of Siskiyou Mariposa Lily (Calochortus perisistens) Project (Project)

CDFW is issuing a permit to U.S. Forest Service pursuant to Fish and Game Code section 2081(a) for a project to collect, export, and propagate seed, and to import and outplant seedlings of Siskiyou mariposa lily, a state-listed rare plant species. The project is being implemented as part of a Conservation Agreement between U.S. Fish and Wildlife Service and the Bureau of Land Management. The Conservation Agreement specifies conservation actions for Siskiyou mariposa lily, including development of seed gerination and cultivation techniques, and designing guidelines for introduction of plant material into suitable habitat to establish new populations. Seed was collected from Cottonwood Peak and Gunsight Ridge in 2014 and 2016, and was exported to and propagated at Oregon State University. Over 300 seedlings have been propagated and are suitable for outplanting. Seedlings will be imported and outplanted in fall 2017 in suitable habitat identified at Gunsight Ridge and Cottonwood Peak. The purpose of the outplanting is to test the success of outplanting methods that can be utilized for planting sites in Oregon where the researchers will attempt to establish new populations. If there is high mortality of outplantings at Gunsight Ridge and Cottonwood Peak, additional seedlings may be improted and outplanted at these sites when they become available. Additional seedlings may not be available for at least three years. In addition, seed will be collected from Gunsight Ridge and Cottonwood Peak for five years beginning in 2017. Approx. 40-60 capsules will be collected in early August. Seeds will be sent to Oregon State University for propagation and research, and to Rae Selling Berry Seed Bank and Plant Conservation Program for long-term conservation storage. The outplanted sites at Gunsight Ridge and Cottonwood Peak will be monitored for five years.
