many types of wetlands
Many types of wetlands
  • Swamp (has trees and/or shrubs)
  • Marsh (salt and fresh)
  • Bog
role in identifying wetlands
Role in identifying wetlands
  • Three parameters of wetlands: hydrology, vegetation, and soils.
  • Hydrology is critical but highly variable.
  • Wetland soils, once developed, are fairly permanent
  • Vegetation provides “clue” of presence or absence or changes in hydrology
upl facu fac facw obl
  • Species vary in their likelihood to be present in or absent from wetlands
  • US Fish and Wildlife Service’s “National List of Plant Species That Occur in Wetlands” lists likelihood of presence in wetlands
  • Morphological adaptations to wet conditions
use of vegetation in delineations
Use of vegetation in delineations
  • Wetland species dominate the wetland
  • Use of plots (upland and wetland)
  • Observations of adaptations
  • Problem situations
problem situations
Problem situations
  • Vegetation changes:
    • cut
    • removed
    • altered
  • Look at other parameters
  • Vegetation is one of the clues to the presence or absence of wetlands
  • Be careful about relying on vegetation exclusively!
