Join Ken Himes and Don Thomas for our fall habitat restoration project at the Caltrans fountain thistle site. This is the twice-a-year event that we have been conducting for over 10 years in partnership with Jake Sigg an d the Yerba Buena Chapter of CNPS, to protect the Federally endangered foun tain thistle.
Fountain thistle (Cirsium fontinale var. f ontinale) is a rare endangered plant that grows in an unusual speciali zed habitat, serpentine seeps. It is found only in a few places on the San Francisco Peninsula and only in San Mateo County.
Our work at this si te is a restoration success story. Once almost completely displaced by juba tagrass (Andean pampas grass), the fountain thistle has largely recovered, as a result of the work done by CNPS volunteers. However, fountain thistle is still under threat from jubatagrass and other non-native plants. By remo ving these invasive plants twice a year, we have succeeded in preservi ng the habitat of the fountain thistle.
