    March 2007

    Presented a slideshow to PG&E on the flora and fauna of a serpentine hillside in India Basin slated for development. As a result, the hillside was designated a sensitive habitat area, thus buying time for the 35 native plant species found there.

  • Mar 5, 2017

    December 2007

    Co-sponsored the Endangered Species Big Year competition, a race against time to see and save all 33 endangered species in the GGNRA.

    This was highly successful program, and was repeated two years later. One of the projects ensuing from this competition was restoration of the federal/state-listed fountain thistle, Cirsium fontinale fontinale, in San Mateo County, a project still continuing. As a result of our hard work [joint with our CNPS Santa Clara Valley Chapter and partnering with Caltrans], resulted in the population of two dozen plants rebounding to around an astounding 6,000 plants, when we stopped counting.

To boot, it was the white-flowered form of this normally yellow-flower plant.

  • Mar 24, 2017

    October 1988

    Convinced the Presidio to remove a number of Monterey pine, blackwood acacia and French broom from the last refuge of the endangered Presidio clarkia (Clarkia franciscana) at Inspiration Point. The huge pine (30" dbh, 60' tall) threatened to usurp the clarkia habitat. (The following year several hundred clarkia seeds germinated and thrived.)

    Negotiated with the Army to restore habitat that they destroyed while constructing an athletic field behind Marine Hospital in the Presidio. Our chapter blew the whistle on the illegal bulldozing, and the story was in blazing headlines on front page of SF Examiner.
    Worked with Recreation and Park and the Department of Public Works to keep pedestrian paths from encroaching on the thriving wildflower community on Corona Heights.

    Partnered with Recreation and Park and the Department of Public Works to create one stairway and shore up the existing one to prevent erosion and protect a remnant coastal strand community at Grandview Park. In addition, the chapter created signs to help inform the public about the unique geographical features and flora of the hill.

    Propagated seeds and cuttings collected at Grandview Park that were planted by volunteers from the Golden Gate Heights Neighborhood Association.

    Took an unauthorized memorial and redwood planting on Mt Davidson wildflower fields to the Recreation and Park Commission, which ordered removal and restoration.

    Allied with the Sierra Club and Recreation and Park to remove a quarter acre of French broom from Mount Davidson.
