Listen as we explore issues, ideas and research about wetlands in Canada.
Wetlands are some of the most bio-diverse habitats in the country. Wetlands are vital to the health of a wide variety of mammals, birds, amphibians reptiles plants—and, of course human beings. We’re interviewing research experts and frontline workers from Ducks Unlimited Canada in lively, engaging exchanges. They’ll keep you up-to-date and up-to-speed on the best information and stories about these vital Canadian ecosystems.DUC Podcast on iTunes
In this episode you’ll meet carp in a marsh and a researcher in the field. First, the carp.
In it’s heyday, the 1930s, the Delta Marsh, near Lake Manitoba, was home to a huge numbers of waterfowl. It was one of the great duck hunting destinations in North America. And, it attracted royalty, celebrities and hunters from all over the world. That was, before the carp. The invasive species muddied the marshes water, stirred up the bottom and generally made life miserable for the aquatic plants that called the marsh home. No plants, no ducks. Then scientists perfected the carp barrier and the marsh is bouncing back (see how it works). You’ll hear the story of a remarkable recovery.
Next we pay a short visit to Matt Dyson a University of Waterloo field researcher. He tells us what it’s really like in the woods, bogs and muck of the north as he does the real, on the ground work of a deep woods scientist.Download Episode File
Dale Wrubleski, PhD
Dale is Ducks Unlimited Canada’s lead research scientist at Delta Marsh. Trained as an entomologist, Wrubleski has more recently become an expert on native fish species and on the invasive carp that threaten the famed Manitoba wetland.
Glen grew up near the shores of Delta Marsh in the 1970s. Over the years, he’s seen the health of the iconic wetland deteriorate, as well as unsuccessful attempts to improve conditions. Rather than become discouraged, Suggett’s a part of the team working to restore Delta Marsh for the next generation. Together with Gordon Goldsborough, PhD, and members of the Delta History Group, Suggett authored Delta: A Prairie Marsh and its People, a book that introduces readers to the people who have relied on and enjoyed the marsh over the years.
Gordon Goldsborough, PhD.
Few people know the history of Manitoba’s Delta Marsh as intimately as Gordon Goldsborough, PhD. A Winnipeg-born research scientist and natural storyteller, Goldsborough’s connection to Delta dates back to his days as a student at the University of Manitoba. As a water quality specialist, and professor at his alma mater, Goldsborough enjoys sharing the many reasons why Delta Marsh is so important for people and wildlife.
Matt Dyson’s Twitter feed, much like his life, is anything but boring. The University of Waterloo student’s tweets alternate with images of cougars and ravens eating duck eggs. The photos of ravenous predators—captured by trail cameras—are part of Dyson’s ongoing doctoral research that takes him to northern Alberta each spring. While battling the landscape’s rugged elements, he’s studying the impact a changing boreal forest is having on predators—and in turn, on duck populations.
