World Wetlands Day

Across the country, powerful ecosystems are protecting our water resources. They are Canada’s wetlands.

Powerful ecosystems — Protecting our water resources

Wetlands underpin almost every aspect of our water’s health 

They buffer our coastlines from rising tides and extreme weather. The plants that grow in wetlands filter and clean the water that moves across the land and enters our lakes and rivers. 

Now, more than ever, their ability to provide solutions to our most pressing water issues demands recognition—and action. 

On World Wetlands Day,  join us and commit to conserving these vital ecosystems.

Why wetlands matter

And need protection

SCIENCE STORIES 

For more than 82 years, DUC has been conserving wetlands and studying the benefits they provide to both wildlife and people. Through our science and our stories, we can help answer the question:

What do wetlands really do for our water? 

They clean it.

Case study: St-Pierre-Jolys, Manitoba

When the town of St-Pierre-Jolys began using a constructed wetland to clean water flowing from its lagoon, water tests showed that phosphorus levels dropped significantly.

  • Phosphorus in the lagoon water was more than 70% higher than allowed by provincial guidelines
  • Phosphorus in the wetland-treated water dropped to be 97% lower than allowed by provincial guidelines
  • The water released from the wetland contained significantly less phosphorus than the river it flowed into

FAST FACT: Per person, Canada has the world’s largest supply of renewable fresh water. But we can’t take it for granted. Wetlands play a critical role in proving us with cleaner, safer water.

Harnessing wetlands as green infrastructure solutions to our water woes

They help protect us from flooding.

Case study: Camrose Creek, Alberta

Research shows that wetlands, serving as natural infrastructure in this central Alberta watershed, provide ecosystem services and environmental benefits at an estimated value of:

  • $1.25 million in flood protection
  • $1.8 million in social benefits
  • Approximately 900,000 tonnes of carbon stored

FAST FACT: Coastal wetlands and salt marshes act as nature’s defence system: They reduce coastal energy by lowering the amplitude and speed of ocean waves and they mitigate storm damage. They also shield coastlines from erosion.

Years of planning and partnership among Stewardship Oxford, DUC, the Upper Thames River Conservation Authority, Oxford County and the City of Woodstock are paying out in the only green that really matters.

Sea-level rise is no longer something discussed in the abstract. The science is settled. Ducks Unlimited Canada and the City of Richmond partner to protect the tidal wetland habitats.

DUC reverts decades-old freshwater marsh to saltwater to protect New Brunswick coastline from sea-level rise and provide habitat for endangered species.

They protect rivers, lakes and beaches from algae blooms.

Case study: Restored wetlands in southern Ontario

Current research near Lake Erie is showing that restored wetlands are “phosphorus sinks,” removing excess nutrients that can cause blue-green algae outbreaks. The eight wetlands in the study all receive surface-water runoff from agricultural fields. Early findings include:

  • Overall reduction by 59% of the most problematic form of phosphorus
  • Three of the wetlands reduced phosphorus by 93-99%

FAST FACT: Conserving an area of wetland equal to the size of the average Canadian home will stop 0.05 kilograms of phosphorus and 0.19 kilograms of nitrogen from entering our lakes and rivers every year (helping to prevent harmful blue-green algae).

Your membership with Ducks Unlimited Canada helps to create a cleaner environment for future generations. It only takes a $50 donation, matched by our partners, to conserve an area of wetlands equal to the size of an average home. That habitat stores five tonnes of carbon and 41,000 litres of water and filters out pollutants.
