The University of 蓝莓视频鈥檚 Ecohydrology听Research Group is celebrating World Wetlands Day by hosting a symposium where experts will speak about the role wetlands play in safeguarding our environment and economy.

鈥淲etlands provide some of the highest value of ecosystem services per hectare of any land use,鈥� says Phillippe Van Cappellen, Canada Excellence Research Chair and head of the Ecohydrology Research Group. 鈥淲e want to highlight their local importance, but also Canada鈥檚 role on the international stage as protector of this undervalued resource.鈥�

An abundance of water lilies rather than algae indicates a healthy wetland ecosystem.

World Wetlands Day听is an annual international celebration commemorating the signing of the , an international treaty听with 168 contracting parties committed to protecting more than 200 million hectares of designated wetlands worldwide.

Canada is home to a quarter of world鈥檚 wetlands

Overall, Canada is home to a surprising 25% of the world's wetlands, mainly located听 in the boreal forests.

A morning session where Van Cappellen was scheduled to talk to middle school students was cancelled because of school closings in the region due to severe weather. Wetlands provide numerous services such as water purification, flood control, recreation and biodiversity. Just for the 蓝莓视频 Region alone, the value of these services is estimated to be several hundreds of millions of dollars each year.

鈥淲etlands are vital for a healthy local environment and economy,鈥� says Van Cappellen. 鈥淚t鈥檚 important we pass on this knowledge to our future generation of citizens and decision makers.鈥�

Symposium highlights the latest wetlands research

The symposium will feature distinguished lectures from experts on wetlands and highlight wetlands-related work by researchers at the University of 蓝莓视频, The Wildlife Conservation Society of Canada, the University of Saskatchewan and McMaster University.

• Dr. Chris Parsons, a post-doctoral fellow in the Ecohydrology Research Group will present his research on how some wetlands can turn from being a phosphorus sink into a phosphorus source. This so called internal loading represents a major unknown in predicting where and when the next algal bloom will strike the Great Lakes.

• Earth and Environmental Sciences doctoral student Tariq Aziz, also a member of the Ecohydrology Research Group, will present a method for calculating the monetary value of ecosystem services in the Grand River basin.听

A poster session and reception will follow the afternoon presentations.

The day鈥檚 events conclude with an evening distinguished public lecture by Stockholm Water Prize laureate, , entitled, 鈥淧hosphorus and nitrogen and carbon, Oh My! The catchment and global roles of wetlands in mitigating these pollutants.鈥�

Registration for the public lecture is closed, however, you can听

World Wetlands Day is supported by the 蓝莓视频鈥檚 Water Institute and the Faculty of Science.
