Friends of Alhambra Creek (FoAC) was established in 1991 in the City of Martinez by a group of volunteers who wanted to ensure the care of Alhambra Creek and the greater Alhambra Creek Watershed. FoAC has promoted and participated in local creek projects and habitat enhancement since its inception.

Working with the City of Martinez, the Martinez Unified School District, Mt. View Sanitary District, the National Park Service, and the Contra Costa Resource Conservation District, FoAC has successfully removed patches of giant reed (Arundo donax), broadleaved pepperweed (Lepidium latifolium), stinkwort (Dittrichia graveolens), Mexican feathergrass (Stipa tenuissima), and other invasive plants from Alhambra Creek, a local housing development, and nearby marsh lands. Eradicating these species from the Watershed will be an uphill battle, but FoAC is up for the challenge. For the last three years, FoAC has been removing stinkwort from McNabney Marsh with noticeable results. This year, it was satisfyingly difficult to find stinkwort at the marsh!

One of FoAC’s notable projects is the Alhambra Native Plant Trail — a series of small California native pollinator gardens that were installed in formerly neglected, weedy areas. The first of these gardens was installed in 2010, and since then, the Trail has blossomed into 18 gardens located throughout Martinez. Every Monday, FoAC volunteers work to maintain the gardens, and weed management makes up a large part of that ongoing maintenance.
