Stu and city staff from Pacific Grove successfully completed another year of adaptive management at Monarch Grove Sanctuary.  The monarchs returned (11,500 Thanksgiving count) and are taking advantage of the wind shelter provided by blue gum trees planted in 1999, and sipping from the nectar gardens.  Stu continues to network with other monarch scientists around the world.

New endangered San Mateo thornmint colonies seeded at Edgewood Natural Preserve

In Restoration on January 11, 2016 at 2:01 pm


On December 4, 2015, Creekside staff and Edgewood volunteers seeded three additional colonies of federal- and state-endangered San Mateo thornmint at Edgewood Natural Preserve. These additional colonies are key to preventing extinction of this annual forb which exists in the wild only at one additional colony at Edgewood. Funding for this project has been generously provided by the Friends of Edgewood.


By January 8, 2016, all 80 square meter plots had some germinated thornmint in them.



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

In Restoration on December 8, 2015 at 1:51 pm

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.
