        habitat, several riparian corridors, extensive wetlands, ponds 
        and other water sources, cypress groves, meadows, and sand

        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
