    • The San Francisco “Six” The City’s Worst Wildland Weeds brochure

Project Highlights:

   Endangered Species Habitat Restoration on Twin Peaks (2009)

  • To eliminate a major infestation of invasive weeds, including principally, French broom, cape and English ivies, gorse and cotoneaster from within and adjacent to a core critical section of endangered species habitat. Project objectives were the elimination of invasives, educate public about invasives, and initiate long term volunteer stewardship program. Methods for control were combination of mechanical equipment, hand removal, power tools, herbicide and goats.

   Initial Priority Weed Assessment and Strategic Plan Update (2010)

  • To assemble existing information across jurisdictions about top priority weed species in both tabular and basic geographic format, and in doing so to strengthen our interconnected multi-agency collaboration. Project objectives were to establish communication system among all county weed professionals, create initial report/extent of priority weeds in the county, and update SFMWA Strategic Plan. Methods of performance are the number of new members in the WMA and create a contact list of county wide weed professionals, all MOU members and other weed management entities create share all their weed data, and have a current strategic plan representing consensus among participants of county’s goals.

Algerian Sea Lavender Management at Heron’s Head Park and Southeast San Francisco (2020)

  • To continue knocking back Limonium ramosissimum from the saltmarshes of San Francisco as part of the larger baywide management program by the Invasive Spartina Project.

Dittrichia viscosa eradication at Hunter’s Point Shipyard (2021-)

  • To eradicate Dittrichia viscosa from Hunter’s Point Shipyard, one of only two or three known populations in North America. This species is of the highest priority for eradication. It was very established at the Shipyard. The San Francisco Agricultural Commissioner’s office (housed in the Department of Public Health, Division of Environmental Health) has been coordinating with the Navy, SF Environment, the California Invasive Plant Council, and weed management contractors to collaboratively address this problem.
