    (a) Findings.--Congress finds that--
            (1) the Point Arena-Stornetta Public Lands contain 
        significant natural resources, including important wildlife 
        habitat, several riparian corridors, extensive wetlands, ponds 
        and other water sources, cypress groves, meadows, and sand 
        dunes that should be preserved for present and future 
        generations;
            (2) the ocean and coastal ecosystems adjacent to the Point 
        Arena-Stornetta Public Lands are internationally recognized as 
        significant centers of coastal upwelling that support the 
        diverse, abundant, and productive marine ecosystems and 
        wildlife underlying the local economy and identity of coastal 
        communities;
            (3) the Point Arena-Stornetta Public Lands tell an 
        important story about the coastal prehistory and history of 
        California in the context of the surrounding region and 
        communities;
            (4) the coastal area surrounding the Point Arena-Stornetta 
        Public Lands was traditionally used by Indian people, including 
        the Pomo Indian tribes;
            (5) the Point Arena-Stornetta Public Lands are historically 
        associated with adjacent land managed for the enjoyment of 
        current and future generations, including the Arena Rock Marine 
        Natural Preserve, and Manchester Beach State Park;
            (6) the Point Arena-Stornetta Public Lands represent a 
        model partnership where future management can be successfully 
        accomplished among the Federal Government, State of California, 
        Mendocino County, local communities, and private groups;
            (7) permanent protection of the Point Arena-Stornetta 
        Public Lands will provide important economic benefits to 
        surrounding communities, and has broad public support;
            (8) the Point Arena-Stornetta Public Lands would make a 
        significant addition to the California Coastal National 
        Monument and National Landscape Conservation System 
        administered by the Bureau of Land Management of the Department 
        of the Interior; and
            (9) statutory protection is necessary to ensure that the 
        Point Arena-Stornetta Public Lands remain a part of the 
        historical, cultural, and natural heritage of the United States 
        and a source of inspiration for the people of the United 
        States.
    (b) Purpose.--The purpose of this Act is to protect, conserve, and 
enhance for the benefit and enjoyment of present and future generations 
the unique and nationally important historical, natural, cultural,
