Management Alternatives related to public use. A detailed description of the wildlife and habitat management activities currently being implemented on the Refuge, as well as the Refuge’s current public use program, are described in detail in Section 3.3.3.1 (Alternative A - No Action). 3.4 Proposed Management Alternatives Before the process of developing alternatives began, the planning team reviewed and evaluated both the comments received during the initial phases of the CCP planning process, including scoping, as well as the issues, management concerns, threats, and opportunities presented in Chapter 2 of this document. Through further analysis of the issues and general public comment, the team developed various objectives for achieving Refuge goals, the mission of the NWRS, and other mandates. Based on the objectives and an analysis of the types of strategies that might be implemented to achieve the objectives, a range of draft alternatives were developed for how the Refuge should be managed over the next 15 years. These draft alternatives were further refined during the analysis of environmental consequences. As a result of this process, three management alternatives, including a no action alternative and two action alternatives, were developed for evaluation in the draft CCP/EA. The three alternatives differ in the extent and focus of wildlife and habitat management actions to be implemented on the Refuge and in the types and levels of public use opportunities to be provided. Management Alternative “C” represents the proposed action. Following consideration of the comments received during public review of the draft CCP/EA, this alternative may be altered to include one or more of the actions addressed in another alternative, or some elements of the alternative may be modified or deleted. The preferred management alternative will be described in the Final CCP. 3.4.1 Summary of Alternatives The three management alternatives evaluated for the Seal Beach NWR are summarized below and described in greater detail in the sections that follow. Alternative A - No Action Under this alternative, past and present management activities would remain unchanged. Current conservation and management actions would continue per available funding and wildlife observation, interpretation, and environmental education would continue at current levels. This alternative represents the baseline from which other “action” alternatives will be evaluated. Alternative B – Maximize Salt Marsh Restoration, Continue Current Public Uses Under this alternative, current wildlife and habitat management activities would be expanded to include evaluation of current baseline data for fish, wildlife, and plants on the Refuge, identification of data gaps, implementation of species surveys to address data gaps as staff time and funding allows, and support for new research projects that would benefit Refuge resources and Refuge management. Also proposed is the restoration of approximately 22 acres of intertidal habitat (salt marsh and intertidal mudflat) and 15 acres of wetland/upland transition habitat. Pest control would be implemented in accordance with an Integrated Pest Management program and mosquito monitoring and control would be guided by a Mosquito Management Plan. No changes to the current public use program are proposed. Alternative C (Proposed Action) - Optimize Upland/Wetland Restoration, Improve Opportunities for Wildlife Observation The majority of the management activities proposed in Alternative B would also be implemented under this Alternative. The primary difference between Alternatives B and C is that under Draft Comprehensive Conservation Plan/Environmental Assessment 3-7
Chapter 3 Alternative C a larger portion of the areas to be restored would consist of upland and wetland/upland transition habitat. Under this alternative, approximately 12 acres would be restored to upland habitat, approximately 10 acres would be restored to wetland/upland transition habitat, and approximately 15 acres would be restored to intertidal habitat. In addition, Alternative C includes limited expansion of the current public use program, including expanded opportunities for wildlife observation. 3.4.2 Similarities Among the Alternatives Although there are differences among the range of alternatives presented for managing the Seal Beach NWR, the alternatives also include various features and management components that would be part of the CCP regardless of the alternative selected for implementation. 3.4.2.1 Features Common to All Alternatives Features common to all alternatives are summarized below. To reduce repetition in the alternatives descriptions, those features that are common among all of the alternatives are described in detail only under Alternative A – No Action. Monitoring of Listed Species – Annual monitoring of California least terns and light-footed clapper rails would continue, per available funding. Monitoring involves site visits during the nesting season for both species to record numbers of pairs and nests, and to estimate the numbers of chicks fledged. Fall high tide and spring call counts for rails are also conducted. Management of NASA Island to Support California Least Tern Nesting – Site preparation prior to the nesting season would continue at NASA Island, as would measures to reduce the potential for predation by mammalian and avian species. Actions to Improve the Reproductive Success and Genetic Diversity of the Refuge’s Light-footed Clapper Rail Population – Nesting platforms installed in the marsh improve the rails’ potential to successful raise their young. Annual inspection, maintenance, and replacement of these platforms would continue under all alternatives. In addition, periodic releases of captive-bred rails would continue to ensure genetic diversity within the population. Mosquito Monitoring and Control – Under all alternatives, the Orange County Vector Control District would be allowed to monitor and manage mosquito populations on the Refuge for public health and safety purposes. These activities are permitted through the issuance of annual Special Use Permits. Invasive Plant Species Control – Periodic control of invasive plant species, involving the use of Service approved herbicides, would be conducted in upland and upland transition areas of the Refuge. Service approved pesticides (which include herbicides) would be used under all alternatives. Pesticide approvals would include a detailed evaluation of the proposed pesticide noting environmental hazards, efficacy, vulnerability of the target pest, and the Stateissued Certified Pesticide Applicators’ identification number for proposed use of any restricted use pesticides. 3-8 Seal Beach National Wildlife Refuge
