Constraints on recruitment of a rare serpentine seep endemic, Cirsium fontinale var. campylon (Mt. Hamilton thistle) I am conducting an autecological study to examine environmental and biological constraints on the recruitment of the rare endemic Mt. Hamilton thistle (Cirsium fontinale var. campylon; CNPS List 1B, Federal Species of Concern) a perennial plant restricted to serpentine seeps in Alameda, Santa Clara and Stanislaus Counties. |
