Sycamore Alluvial Woodland

Sycamore Alluvial Woodland is a rare open woodland plant community, or vegetation type, dominated by California sycamore Platanus racemosa, existing only in small parts of California. It exists only in small areas of California in the foothills of the southern Sierra Nevada range and the California Coastal Range. It is rare as a plant community, even though California sycamore is a common component of other vegetation types where it is not dominant. It exists at the base of flat valleys having deep alluvial gravel, where water from the hills hit the flat valley floor having an intermittent stream and large seasonal fluctuations in the water table.
