Project highlights include the following:

• The exiting 3500m² wetland area was enlarged to 7000m²

• 15 days of construction (Sept 12th to Sept 30th 2016)

• 1225 m² of buckthorn removed (invasive species)

• 389 native trees and shrubs were planted

5.5kg of shoreline and wetland seed mixes were installed

19 volunteers for a total of 76 volunteer hours participated in the stabilization work

15 root wads and 12 sweeper trees were installed along the shoreline of the wetland.


Wetland Restoration in the Greenbelt

The NCC is collaborating with the Rideau Valley Conservation Authority (RVCA) and the Great Lakes Guardian Community Fund to design and construct a wetland in the headwaters of Black Rapids Creek, located in the Greenbelt. The wetland will:


• improve water quality

• provide rare wetland habitat along the Black Rapids Creek system

• increase overall biodiversity

 

About the project

The existing shallow wetland feature is an area of 3444 square metres and will more than double post construction.  A tributary that presently bypasses the wetland will be redirected through the newly constructed wetland and will provide a larger wetland feature that supports amphibian breeding, fish habitat, bird foraging, and act as a water supply for wildlife.  The work planned for September 2016, includes:


• repositioning of fill from the existing work zone to create a wetland feature with
  a variety of side slopes

• installation of woody debris (i.e. root wads, basking logs and sweeper trees)

• re-vegetation of the riparian area by planting native trees, shrubs and
  wetland vegetation

 

Post effectiveness monitoring of the new wetland feature is planned for 2017, 2019, 2021.

Project Benefits

Ecologial

  • Increased wetland habitat in the catchment
  • Improved water quality for Black Rapids Creek and the Rideau River
  • More diverse submergent and emergent aquatic vegetation
  • New and enhanced winter and summer refuge areas for aquatic organisms (i.e. turtles, amphibians, etc.)
  • A quiet area for waterfowl to rear their young and an area for shorebirds to feed

 

  • Increased biodiversity of aquatic/terrestrial plants and wildlife
  • Enhanced habitat diversity by installing wood structure in the form of trees, stumps and large branches

Social

  • Potential for Interpretive signage describing the project and its benefits to Black Rapids Creek and the Rideau River
  • An opportunity for community groups and local NGO’s to participate in the construction and post effectiveness monitoring activity
  • Use of the site for environmental educational opportunities centered on learning about wetland/habitat restoration activities
  • A unique habitat feature along the National Capital Commission Greenbelt Pathway system with high visibility
