Excavation in a palustrine or lacustrine wetland

Excavation in a palustrine or lacustrine wetland increases the extent and/or depth and may increase the persistence of water in the wetland. In some cases, excavation in a palustrine wetland may increase wetland extent and depth to such a degree that the wetland is converted to a lacustrine wetland system.

Applicable Wetland Habitat Hydrological Modification:

  • 'Modified – excavation outside a channel – freshwater wetland with no system change' (H2-M11-a)
  • 'Modified – excavation outside a channel – freshwater wetland with system change' (H2-M11-b)

Excavation causing conversion to an intertidal wetland

Excavation in a palustrine or lacustrine wetland increases the extent and/or depth of the wetland but also enables tidal inundation. The wetland is converted to an intertidal wetland.

Applicable Wetland Habitat Hydrological Modification:

  • 'Modified – excavation outside a channel – freshwater wetland with system change to intertidal' (H2-M11-c)

Excavation in an intertidal wetland

Excavation in an intertidal wetland increases the extent and/or depth of the wetland but does not restrict tidal inundation.

Applicable Wetland Habitat Hydrological Modification:

  • 'Modified – excavation outside a channel – intertidal wetland with no system change' (H2-M11-d)
