Eriocaulon parkeri - Polygonum punctatum Tidal Marsh
Translated Name: Estuary Pipewort - Dotted Smartweed Tidal Marsh
Common Name: Estuary Pipewort Freshwater Intertidal Flat
Unique Identifier: CEGL006352
Classification Approach: International Vegetation Classification (IVC)
Summary: This freshwater tidal community occurs in estuaries of the northern Atlantic Coast generally confined to low marsh where it is subjected to high levels of flood disturbance. As a result, the substrate is generally sandy or gravelly with low organic matter content. The vegetation is low, generally less than 35 cm in height, with variable cover of scattered to fairly dense Eriocaulon parkeri. Associates include Polygonum punctatum, Isoetes riparia, Lindernia dubia, Bidens eatonii, and Ludwigia palustris.



Classification

Classification Confidence: Low - Poorly Documented
Classification Comments: The floristics and environmental setting of this association show overlap with Isoetes riparia Tidal Marsh (CEGL006058).

NatureServe Conservation Status
Global Status: G2 (09Nov1998)
Rounded Global Status: G2 - Imperiled
Reasons: This freshwater to brackish-tidal vegetation is restricted to sandy, gravel or cobble shores of tidal rivers from southern Maine to North Carolina, with possible peripheral occurrences in South Carolina and New Brunswick, Canada. This community is extirpated from New York. The habitat is naturally rare and occurrences are of small size (generally a few acres or less). The vegetation is threatened by damming of tidal rivers, which causes silting and reduces the flushing of fine sediments necessary to maintain this community.

Vegetation

Vegetation Summary: This community is an herbaceous (95% cover) wetland dominated by annuals or herbaceous perennials. Eriocaulon parkeri is characteristic of this association. In the northern portion of the range, associated species include Zizania aquatica, Ludwigia palustris, Bidens eatonii, Bidens hyperborea, Crassula aquatica, and Schoenoplectus pungens. Farther south, associates additionally include Sagittaria latifolia, Pontederia cordata, Peltandra virginica, and Orontium aquaticum. Vegetation cover can be highly variable with significant fluctuations in floristic composition and species density from year to year. Seasonal variability also occurs; early in the season, Isoetes spp. can predominate. Several regionally rare species occur in this type including Eriocaulon parkeri, Limosella australis, Bidens eatonii, and Crassula aquatica.

Environmental Setting

Wetland Indicator: Y
Environmental Summary: This community occurs within freshwater tidal wetland complexes in upper reaches of tides where there is seasonal flushing which removes accumulated fine-grained materials. The typical substrate consists of loamy sand with about 5% gravel. The moisture regime is very wet with the community being exposed during low tide and often remaining inundated during spring tides.
