Proiect Description for 2008 Control Program <br />The success of Spartina treatment from 2005-2007 has enabled the ISP to shift into the <br />next phase of the project. The majority of sites have been reduced significantly to a more <br />scattered distribution over the previous footprint of the infestation. This progress <br />necessitates for each year a heightened focus on both identifying and subsequently <br />treating remaining patches and then each and every plant of invasive Spartina throughout <br />the Estuary to bring the project closer to the ultimate goal of eradication. In 2008, a <br />higher percentage of treatment will be conducted by spot applications and manual <br />control, replacing the large, mostly aerial broadcast applications that were appropriate at <br />the start of the project when some site complexes had hundreds of contiguous acres of <br />non-native Spartina. As a result, there will be a significant increase in labor costs, both <br />for ISP monitoring crews and for the grantees' treatment contractors. <br />ISP management of the Control Program includes completing three-year updates of 24 <br />treatment plans covering 156 sub-areas, including one new site plan (North San Pablo <br />Bay), and submitting these documents to the US Fish and Wildlife Service (FWS) for an <br />amended Biological Opinion to authorize treatment. Other ongoing ISP responsibilities <br />include making presentations to regional stakeholders, obtaining necessary permits, <br />preparing and implementing I5P's Water Quality Monitoring Plan and reports, <br />continuing the inventory monitoring and California clapper rail monitoring, continuing <br />the telemetry study examining Clapper rail movement, coordinating replanting in Corte <br />Madera Creek watershed and some East Bay Regional Park District sites, and continuing <br />to seek landowner permissions to work on sites where work has not previously been <br />done. <br />Treatment will also extend over a longer season in 2008. Clapper rail monitoring over the <br />past three years has shown an increase in the number of rails at treated sites rather than <br />the decrease that was expected. As a result, FWS is expected to approve eazlier access to <br />some clapper rail sites to increase efficacy and expand the potential treatment window to <br />accommodate the increased work load of ground-based treatment and spot control that <br />will replace broadcast applications. <br />The ISP also conducted a drift card study which found that simulated seeds in drift cazd <br />form can travel from heavily infested sites to Point Reyes National Seashore, Stinson <br />Beach, and other areas of the outer coast. Cards also released from infested sites in the <br />Central Bay turned up in the Don Edwards National Wildlife Refuge and in areas of the <br />South Bay Salt Ponds that are scheduled to be opened to tidal exchange in the neaz future. <br />These findings add a sense of immediacy to the goal of eradication which will be <br />facilitated by approval of a longer treatment window with earlier access to clapper rail <br />sites. <br />As would be expected given the results of the drift card study, small infestations of <br />invasive Spartina, likely originating from seeds from the San Francisco Estuary, are <br />found along the Marin coastline at Tomales Bay, Drakes Estero, Limantour Estero, and <br />Bolinas Lagoon. (See Exhibit 4, Map of Coastal Marin Infestations.) Altogether these <br />plants cover less than one acre. For the past few years ISP assisted the National Pazk <br /> <br />
