Castilleja affinis neglecta seeded at Coyote Ridge and the Creekside Growing Facility

On November 23, 2015, Creekside staff experimentally seeded federally endangered Castilleja affinis neglecta to enhance the Paintbrush Canyon population at Coyote Ridge. Plots will compare different seeding densities, irrigation, and stratification treatments against a control.


A seed increase project continues at the Creekside Growing Facility, where Castilleja are grown with Achillea millefolium hosts. Seeding is the preferred method of restoration while concerns about Phytophthora or other pathogens in nursery stock exist. On December 3 and 8, 2015, a total of 2100 seeds were planted at the facility.
