Redwood Creek Native Plant Nursery : ウィキペディア英語版 | Redwood Creek Native Plant Nursery
Redwood Creek Native Plant Nursery is just outside the old-growth redwood forest at Muir Woods National Monument. The nursery provides plants for restoration of the creek bank in the lower watershed and impacted areas of the Muir Woods’ redwood understory. ==Location== The Redwood Creek watershed extends from the peaks of Mt. Tamalpais, Marin County’s tallest mountain, to the Pacific Ocean and is nestled in one of the nation’s most densely populated regions. This watershed encompasses an area of less than nine square miles, yet it harbors incredibly diverse ecosystems with a rich assemblage of plant and animal species. Within this small watershed are found grasslands, coastal chaparral, mixed hardwood and old-growth redwood forest, seasonal wetlands,and riparian woodlands that extend in an unbroken mosaic from the mountain’s ridge tops to the sea. The watershed is also home to some of the West Coast’s most imperiled species, such as coho salmon (''Oncorhyncus kisutch''), steelhead trout (''O. mykiss''), northern spotted owl (''Strix occidentalis caurina''), and the California red-legged frog (''Rana aurora draytonii’’).〔(“The Watershed.” Redwood Creek Watershed: Vision for the Future )〕 The Redwood Creek watershed is 95% public lands, and holds Muir Woods National Monument, as well as the communities of Muir Beach and Green Gulch Farm. An indication of it ecological value is that the watershed is one of 25 global biodiversity “hot spots” recognized by (The Nature Conservancy ) and targeted by the global conservation community as key to preserving the worlds’ ecosystem 〔Stein, B.A., L.S. Kutner, and J.S. Adams, eds. Precious Heritage: The Status of Biodiversity in the United States. Oxford: Oxford University Press. 2000.〕 It is also within the Golden Gate Biosphere Reserve, one of 411 reserves designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) "Man and the Biosphere" Program to provide a global network representing the world’s major ecosystem types.〔UNESCO.
