Excavation forming an artificial palustrine or lacustrine wetland

Excavation outside natural and/or modified natural wetlands is often intended to capture overland flow (i.e., surface water runoff) and may create an artificial palustrine or lacustrine wetland.

Applicable Wetland Habitat Hydrological Modification:

• 'Artificial – excavation – freshwater wetland' (H3-C5-a).

Excavation forming an artificial intertidal wetland

Excavation outside of natural and/or modified natural wetlands is often intended to capture overland flow (i.e., surface water runoff). Where the excavated area is connected to estuaries or intertidal wetlands, this may create an artificial intertidal wetland.

Applicable Wetland Habitat Hydrological Modification:

• 'Artificial – excavation – intertidal wetland' (H3-C5-b)
