        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

        underlying the local economy and identity of coastal 
        communities.
            (3) The Point Arena-Stornetta Public Lands tell an 
        important story about California's coastal prehistory and 
        history in the context of the surrounding region and
