V. HERBACEOUS
VEGETATION Concept: This alliance contains oligohaline to mesohaline marshes dominated by Carex hyalinolepis that form adjacent to main channels of tidal rivers in Virginia and Maryland. Carex hyalinolepis forms nearly monospecific stands. Associated species occurring with low cover include Hibiscus moscheutos ssp. moscheutos, Kosteletzkya virginica, and Spartina cynosuroides. Range: This alliance is currently described from Virginia and Maryland. States/Provinces: MD VA TNC Ecoregions: 58:C USFS Ecoregions: 232Br:CCC, 232Bt:CCC References: Coulling 2002, Harrison pers. comm. Authors: P.P. COULLING AND S.L. NE, East Identifier: A.3019 CAREX HYALINOLEPIS TIDAL HERBACEOUS VEGETATION Shoreline Sedge Tidal Herbaceous Vegetation G? (02-05-10) Concept: 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. Comments: On the Rapphannock 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). Range: This community type has been documented only from the Pamunkey River (Hill and Lee marshes) in Virginia. States/Provinces: MD:S?, VA:S?
