Site#	Year Started	Status	Name
004	2004	Active	Corte Madera Creek Complex Marin County
	Description
	The Corte Madera Creek complex is located on the west side of the North San Francisco Bay in Marin County, south of the San Quentin peninsula and San Rafael Bay. The complex consists of a wide corridor stretching upstream from the mouth of Corte Madera Creek to the uppermost point of non-native Spartina growth in this watershed at about 2.2 miles from the mouth. The entire Corte Madera Creek corridor is heavily developed with upscale residential and commercial facilities. The Corte Madera Creek complex is comprised of 11 distinct sub-areas that occur on both public and private lands, each of which will require different treatment and public outreach approaches. The infestation at the Corte Madera Creek complex is still in a relatively early stage of establishment, with approximately 12 acres scattered over 318 acres, or 4% of the total marsh area. The infestation at this complex contains some unique features, including the only infestation of Spartina anglica in the Bay, as well as the first documented case of Spartina densiflora hybridizing with the native Spartina foliosa. Most of the sub-areas have small S. densiflora infestations (less than 0.5 acre), enabling manual control to be used in conjunction with spot herbicide treatments. One sub-area also has Spartina alterniflora hybrids, bringing the overall site total to three of the four invasive cordgrass species currently found in the Bay. The treatment methods at this site include a combination of manual digging, covering with geotextile fabric, and application of aquatic herbicide by backpack sprayer. Partners on this site include the Friends of the Corte Madera Creek Watershed, California Department of Fish and Game, California State Lands Commission, College of Marin, City of Larkspur, Golden Gate Bridge Highway and Transportation District, Marin County Parks and Open Space District, and the Marin County Flood Control and Water Conservation District. Note that this is a complex site composed of multiple sub-areas. Please refer to the Site Specific Plan for detailed descriptions of the sub-areas and the associated treatment methods.
