Sycamore Alluvial Woodland along Dry Creek in the foothills of the Sierra Nevada outside of Woodlake, California (March 16th, 2023)Sierra Nevada Region
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.[1]: 115 It exists only in small areas of California in the foothills of the southern Sierra Nevada range and the California Coastal Range.[1]: 115 It is rare as a plant community, even though California sycamore is a common component of other vegetation types where it is not dominant.[1]: 115 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.[1]: 115 It is a habitat type defined by broad-leafed woodland and stable levels of groundwater.[2] Sycamore Alluvial Woodland is identifiable through open savanna riparian structures, with wide floodplains.[3]
