Sidalcea oregana ssp. valida Stewardship and Seed Viability, Propagation, and Bulking Project
NOE - Notice of Exemption
Present Land Use
The Project will take place in Sonoma County at the remaining wild population of Kenwood Marsh checkerbloom at Deerfield Ranch Winery, located at 10200 Sonoma Highway in Kenwood, Sonoma County (38.405949, -122.542783). Seeds will be germinated and grown at the Sonoma Ecology Center nursery located at Sonoma Garden Park (19996 7th Street East, Sonoma, CA 95476) and bulked seeds will be temporarily stored at the nursery, then sent to the University of California Botanical Garden for long-term conservation storage and use for future projects. Any plants germinated and grown will be kept at the nursery.
The California Department of Fish and Wildlife is issuing a permit to Sonoma Ecology Center Permit No. 2081(a)-20-013-RP pursuant to Fish and Game Code section 2081(a) for a project to address the following tasks: (1) stewardship activities to promote the continued viability of the remaining confirmed population of Kenwood Marsh checkerbloom, such as: population monitoring, collecting seeds for conservation and restoration purposes, expanding the fencing around the population, removing thatch, and monitoring groundwater levels; (2) studies to determine the viability of seeds collected in 2001, 2007, and 2019 to understand how long seeds can remain viable in storage; (3) germination trials on approximately ten percent of the seeds collected in 2007 and 2019, followed by growing the plants to maturity for bulk seed collection; and (4) installing groundwater monitoring stations to supplement those previously installed in the Kenwood Marsh near the remnant population and former outplanting sites nearby. These stations will allow monitoring of changes in seasonal groundwater levels to identify what may be needed to sustain Kenwood Marsh checkerbloom.
