Reintroduction of San Mateo Thornmint to Pulgas Ridge!
For years, the federally endangered San Mateo thornmint was known from only one location at Edgewood Natural Preserve in Redwood City. In the last two seasons, Creekside Science has seeded three new locations within the Preserve, bringing the total number of San Mateo thornmint to 7,549 in May 2017, its highest since we began monitoring…
The Bay Checkerspot Butterfly Returns to San Bruno Mountain!
The federally threatened Bay checkerspot butterfly was extirpated from San Bruno Mountain in the mid 1980s. On March 2 and 3 2017, Creekside Science biologists collected 3630 caterpillars from Coyote Ridge in San Jose and released them on the main ridge of San Bruno Mountain. The larvae immediately started munching English plantain, a non-native used by…

Ardenwood Historic Farm Monarch Habitat Assessment
On January 6, 2017, Creekside Science began site assessment and habitat characterization of Monarch butterfly overwintering habitat at Ardenwood Historic Farm (East Bay Regional Parks District). The primary goal of this project is to conserve the long-term integrity of winter roosting habitat for monarch butterflies at Ardenwood by developing comprehensive site stewardship plans.
Creekside Chief Scientist Flies High Once Again in the Name of Monarch Stewardship
In December 2016 Creekside Chief Scientist Dr. Stuart Weiss was hoisted high into the sky by way of a bucket truck to facilitate Monarch habitat assessment work at Rob Hill in the Presidio. Creekside Science is engaged in canopy characterization to assess seasonal solar radiation, temperature and wind conditions in Monarch butterfly overwintering habitat. Hemispherical…
LAG Grant Award for Monitoring Nitrogen Deposition in Santa Clara County
Creekside Science, in collaboration with the Santa Clara Valley Habitat Agency, has been awarded a Natural Community Conservation Planning (NCCP) Local Assistant Grant for researching nitrogen deposition trends in the HCP area of Santa Clara County. Added nitrogen drives annual grass invasions on serpentine soils and threatens many of the covered species, especially the Bay…
Pacific Grove Monarchs 2015-2016
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…
New endangered San Mateo thornmint colonies seeded at Edgewood Natural Preserve
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…
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…
