CEGL006847 Iva frutescens / Spartina cynosuroides Tidal Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Jesuit''s-bark / Big Cordgrass Shrubland
Colloquial Name: Brackish Shrubland
Hierarchy Level: Association
Type Concept: This brackish tidal shrubland occurs on the mesohaline portion of tidal rivers of the Chesapeake Bay on poorly drained peat overlying sand and mucky sand. This vegetation forms linear bands along levees and bordering tidal guts. Microtopography is relatively flat and lacks pronounced hummocks and hollows. The shrub canopy is moderately dense and codominated by Iva frutescens and Spartina cynosuroides. Other associates include Baccharis halimifolia and Hibiscus moscheutos. The species diversity of this vegetation is relatively low; associated herbs are often found on the edge of the stand and may include Amaranthus cannabinus, Atriplex patula, Lythrum lineare, Polygonum punctatum, Schoenoplectus americanus, Solidago sempervirens, Spartina alterniflora, and Spartina patens.

Floristics: The moderately dense shrub canopy layer is dominated by Iva frutescens. Baccharis halimifolia is a common associate. The herbaceous layer is dominated by Spartina cynosuroides. Other associates may include Amaranthus cannabinus, Atriplex patula, Lythrum lineare, Polygonum punctatum, Schoenoplectus americanus, Solidago sempervirens, Spartina alterniflora, and Spartina patens. Phragmites australis may be present and has been observed to replace Spartina cynosuroides in areas of disturbance.

Environmental Description: This association occurs on diurnally to irregularly tidally flooded oligohaline to mesohaline rivershores. Salinity measures from 7-20 ppt. Microtopography is generally uniform, lacking hummocks and hollows. The substrate is firm, well-consolidated peat overlying sand or mucky peat.
Geographic Range: This vegetation occurs on tidal rivers of the Chesapeake Bay. Its presence in Delaware has not yet been evaluated.
