What is Wetland Restoration?

Wetland restoration is the conversion of degraded wetland back to its original function and characteristics.

Wetland Compensation / Restoration

If you have been requested to compensate for wetland impacts from your Project, The McCallum Environmental Wetland Restoration Team can support you through your process.

In many provinces and states in the U.S., wetland impacts require compensation/restoration measures to ensure no “net loss of wetland area and function, including habitat” occurs.

For example, as required by the Nova Scotia Wetland Conservation Policy (2011), The Environmental Goals and Sustainable Prosperity Act (EGSPA 2007); and, The Environment Act (1994) and its Activities Designation Regulation (1995), wetland impacts in Nova Scotia require compensation/mitigation measures to ensure no “net loss of wetland area and function, including habitat” occurs (EGSPA 2007).

McCallum Environmental supports the process of meeting your goal of no net loss primarily through wetland restoration services, with the potential to complete wetland enhancement or creation/expansion.

What is Wetland Restoration?

Wetland restoration is the conversion of degraded wetland back to its original function and characteristics. 

Examples of wetland degradation include management of water to dry the land (i.e. draining and flooding of land), infilling of wetland habitat, removal or disturbance of wetland vegetation or surface soils or industrial projects (i.e. mining/quarrying) within, or close to wetland habitat.

McCallum Environmental wetland restoration specialists identify wetlands that have been subject to historical degradation, and collaborate with regulators, landowners and our clients (who are required to compensate for wetland loss), to implement valuable wetland restoration projects.

The McCallum Environmental Wetland Restoration Team manages the Wetland Restoration Project including landowner agreements, design and determination of restoration functional objectives, permitting requirements and monitoring of the restoration project to ensure its success.

Recent Projects

Agricultural Restoration (2017 – ongoing)

McCallum Environmental is currently implementing a wetland restoration Project located on agricultural land in Middle Stewiacke, NS. The objectives of this Project are to restore a degraded wetland (which has been historically used for agricultural purposes), back to shallow marsh wetland, interspersed with open water.  This will increase water retention on the landscape and enhance habitat for waterbirds. The approximate size of the restoration project is 17 hectares.

The McCallum Environmental Wetland Restoration Team provided our client support relating to the implementation of suitable wetland soils, and wetland vegetation establishment within the engineered wetland. This included species composition and seeding, and management of hydrological conditions suitable for successful plant growth within the wetland.

In 2017 McCallum Environmental managed the restoration of a former shrub swamp wetland located in in Alton, NS. Activities completed at the site included restoration of altered wetland surfaces (i.e. rutting), removal of vegetation brush piles through mulching and removal of a drainage ditch from the landscape. These activities will enable surface water run-off to be retained at the surface for longer durations and restore wetland functions which existed prior to alteration activities.

Engineered Wetland (2018 ongoing)

In 2018, McCallum Environmental is currently supporting the implementation of an engineered wetland at the Touquoy Gold Mine in Moose River, Nova Scotia.  The engineered wetland receives, and stores water sourced from the on-site Tailings Management Facility, prior to it draining into the natural receiving environment.
