Carex hyalinolepis Tidal Marsh
Translated Name: Shoreline Sedge Tidal Marsh
Common Name: Shoreline Sedge Tidal Marsh
Unique Identifier: CEGL006177
Classification Approach: International Vegetation Classification (IVC)
Summary: This oligohaline marsh, dominated by Carex hyalinolepis, forms adjacent to main tidal river channels in the Chesapeake Bay. Carex hyalinolepis forms nearly monospecific stands. Associated species occurring with low cover include Hibiscus moscheutos ssp. moscheutos, Kosteletzkya virginica, and Spartina cynosuroides.



Classification

Classification Confidence: Low - Poorly Documented
Classification Comments: On the Rappahannock River (White Marsh) a sampled stand is codominated by Carex hyalinolepis and Acorus calamus and supports much greater diversity, but analysis suggests that this plot represents a compositionally different, possibly ecotonal community type. Carex hyalinolepis forms extensive dominance patches in the understories of tidal and wind-tidal oligohaline Taxodium distichum woodlands along the James, North Landing and Northwest rivers. A similar herb stratum has been documented from an apparently seasonally flooded Acer rubrum - Pinus taeda forest adjacent to a tidal marsh along a tributary of Back River in James City County (Coulling 2002).
