	Description
	Cooley Landing is a 165-acre salt marsh restoration site located at the northwestern point of the South San Francisco Bay Estuary, south of the Dumbarton Bridge and adjacent to the point where the Hetch-Hetchy Aqueduct makes landfall on the western shore at Menlo Park. The site is a former salt production evaporator pond that is undergoing restoration to tidal marsh. Initial restoration activities were completed between September and December of 2000, and included the excavation of two breaches through the east levee at locations of historic tidal channels. Re-vegetation of the former salt pond is expected to occur through natural colonization. Performance criteria for the restoration of Cooley Landing requires 70 percent cover of salt marsh vegetation and less than five percent cover of non-native vegetation by the tenth year following restoration. Cooley Landing is part of the Ravenswood Open Space Preserve. Prior to opening Cooley Landing to tidal action in 2000, just five adult clones of invasive Spartina covering a total of 0.1 acre were present along the levees outboard of the restoration area. However, since S. alterniflora hybrids are known to occur on the adjacent properties north and south of the restoration area, and restored salt ponds lack the biotic resistance in the form of an established native plant community, the infestation spread rapidly and already covers 12.0 acres of the restoration site or 7.3% of this large area. Three of the original five clones occur along a levee that has been lowered to approximately mean high water (MHW), facilitating dispersal of invasive Spartina seed to the restoration area. The primary treatment method at this site is aquatic herbicide, which will be applied by conventional spray truck, backpack sprayer, amphibious tracked vehicle, and boat. Partners on this site include the StarLink Logistics, Inc. (SLLI) and the Midpeninsula Regional Open Space District.

Event Definitions

Planned - this control work event has been scheduled by the contractor or ISP partner
Complete - the specific control event for a given date(s) has been completed

The Start and End Date(s) listed below are the expected days for the Control Event based on the estimates provided by the contractor or ISP partner, and are subject to change.

The Control Program is implementing multi-year plans on the non-native Spartina infestations around the San Francisco Estuary. If the status of a Control Program event is listed as "Complete", it refers to the implementation of the plan for the posted event for a given year, and does not imply that the site has yet reached eradication. Please refer to the Site-Specific Plans for more information and a projected timeline to eradication for a given site.
