Habitat [-]
In New York Golden Dock has been almost exclusively in or adjacent to coastal wetlands, including barrier beaches, the edges of saltwater ponds and creeks, interdunal swales, and ballast areas. Saline habitats and possibly inland salt ponds or inland salt marshes represent the habitat of the species in the historical upstate records (New York Natural Heritage Program 2015). Saline, brackish or alkaline marshes and shores, as a weed in disturbed soil (Fernald 1970). Shores, streambanks, and wet ground, avoiding acid soils (Gleason & Cronquist 1991).

Associated Ecological Communities [-]
  • Brackish interdunal swales
    Temporarily tidally flooded temperate marshes in interdunal swales dominated by salt-tolerant graminoids. Individual swales occur as small patches positioned between fore-, primary and secondary dunes in a maritime dunes system, typically on barrier islands.
  • Brackish intertidal shore
    A community of the intertidal gravelly or rocky shores of brackish tidal rivers and creeks where water salinity ranges from 0.5 to 18.0 ppt.
  • Brackish meadow*
    A moist, moderately well-drained brackish (salinity 0.5-18 ppt) perennial grassland with occasional isolated shrubs that is typically situated in a belt at the upper edge of salt marshes bordering sandy uplands, but may occupy large portions of interdunal basins. The community usually develops in areas with a unique combination of soils and hydrology, on deep deposits of periodically windblown or overwashed gleyed sands that are usually flooded only during spring tides and during major coastal storms, approximately two to three times per year.

    * probable association but not confirmed
  • Brackish tidal marsh*
    A marsh community that occurs where water salinity ranges from 0.5 to 18.0 ppt, and water is less than 2 m (6 ft) deep at high tide. The vegetation in a brackish tidal marsh is dense and dominated by tall grass-like plants.

    * probable association but not confirmed
  • Coastal salt pond*
    A community inhabiting marine shoreline lakes or ponds formed by sandspits that close off a lagoon or bay. The water typically averages brackish or slightly brackish over long periods of time, but may range rapidly from fresh to saline.

    * probable association but not confirmed
  • High salt marsh*
    A coastal marsh community that occurs in sheltered areas of the seacoast, in a zone extending from mean high tide up to the limit of spring tides. It is periodically flooded by spring tides and flood tides. High salt marshes typically consist of a mosaic of patches that are mostly dominated by a single graminoid species.

    * probable association but not confirmed
  • Inland salt marsh*
    A wetland that occurs on saline mudflats associated with inland salt springs. The mucky substrate is permanently saturated and seasonally flooded. Plant cover is sparse and the number of different kinds of plants is relatively low.

    * probable association but not confirmed
  • Low salt marsh*
    A coastal marsh community that occurs in sheltered areas of the seacoast, in a zone extending from mean high tide down to mean sea level or to about 2 m (6 ft) below mean high tide. It is regularly flooded by semidiurnal tides. The mean tidal range of low salt marshes on Long Island is about 80 cm, and they often form in basins with a depth of 1.6 m or greater.

    * probable association but not confirmed
  • Maritime beach
    A community with extremely sparse vegetation that occurs on unstable sand, gravel, or cobble ocean shores above mean high tide, where the shore is modified by storm waves and wind erosion.
  • Saltwater tidal creek
    The aquatic community of a shallow, tidally flooded saltwater or brackish creek with submerged areas averaging less than 2 m (6 ft) deep at low tide.
