Geographic Distribution

General Characteristics
  • Low energy
  • Temperate zoneexperience frost
  • Near shore environment
  • Low diversity environmentbut
  • High productivity

5
Vegetation
  • Spartina and Juncus are dominant

  • Specially adapted to salt and water

High productivity
  • High productivity has been exploited for 1000s
    of years by people
