Join Ken Himes and Don Thomas for an in-person conserva tion project to protect the native fountain thistle. Fountai n thistle (Cirsium fontinale var. fontinale) is a rare federally endangered plant that grows in an unu sual specialized habitat, serpentine seeps, and is found onl y in a few locations on the Peninsula. Once almost completel y displaced by jubatagrass (Andean pampas grass), the founta in thistle has largely recovered as a result of the work done by CNPS volun teers.
In keeping with our over 10-year tradition of working with Jak e Sigg and the Yerba Buena Chapter, we are going to continue our biannual f ountain thistle restoration project.
Although our efforts have made t he recovery of fountain thistle a restoration success story, the plant is u nder ongoing threat from jubatagrass and other invasive non- native plants, such as yellow star-thistle, sow thistle and wallaby grass (Rhytidospe rma caespitosum) and by woody plants trying to convert the area to shr ubland or woodland.
We’ll meet at the end of Lessingia Court in San M ateo. For more info., contact Don at don_This email address is b eing protected from spambots. You need JavaScript enabled to view it.. Optional camaraderie over Greek pizza afterwards .
