Join Ken Himes and Don Thomas for an in-person conservation project. In keeping with our 10-year tradition of working with Jake Sigg and the CNPS Yerba Buena Chapter, we are going to continue our spring fountain thistle restoration project. Fountain thistle (Cirsium fontinale var. fontinale) is a rare federally endangered plant that grows in an unusual specialized habitat, serpentine seeps, and is found only in a few locations on the Peninsula.
Our work at this site is a restoration success story. Once almost completely displaced by jubatagrass (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, such as yellow star-thistle, sow thistle and wallaby grass (Rhytidosperma caespitosum). Woody plants are also trying to convert the area to shrubland or woodland.
With increasing vaccinations among CNPS members, COVID-19 social distancing safety measures are being relaxed. However, we are, for now, still observing these basic guidelines:
Physical distancing of workers at least 6 feet apart. Where workers work together, they should maintain this physical distance.
Wearing of face mask or other face covering while working. Face masks must be put on when coming within 30 feet of another worker and be worn the entire time workers are within this distance.
Encourage workers to bring their own tools.
No exchange of tools or other objects unless they
are thoroughly disinfected first.
Encourage workers to wear disposable gloves and disinfect gloves at regular intervals.
Group size to be 10 or fewer people.
