2018 San Mateo Thornmint Update

In Rare species, Restoration, Stewardship on July 19, 2018 at 2:18 pm

2018ThornmintPic2This has been an amazing year for San Mateo thornmint recovery. Creekside Science seeded a new location away from Edgewood Preserve this year, and had a strong showing with all plots occupied and 17% survivorship. We also seeded our three newer sites at Edgewood (for the third year), but for the first time did not seed the original site based on declining habitat quality. Our new sites are performing well, with every cohort increasing this year. The bottom line is we counted 19,187 thornmint at our five sites. This is up from last year’s project high of 7,549, and our project low of 249 in 2008.

Metcalf Canyon Jewelflower on Tulare Hill

In Rare species, Restoration, Stewardship on July 19, 2018 at 2:11 pm

Federally endangered Metcalf Canyon jewelflower continues to passively recruit after three years of active seeding on Tulare Hill in San Jose. In 2017 we documented a total of 412 plants at our plots, which increased to 1,312 in 2018. An exciting find was an additional dozen reproductive plants more than 200 meters from our nearest plot, indicating the plant’s ability to disperse, flower, and fruit on their own.
