Zebra and quagga mussels can seem less like an invasive species and more like an invasive surface. The two mussels, sometimes collectively referred to as dreissenid mussels, are famous for coating lake bottoms, rocks, docks, and boats in sharp, pointed clusters. In this blog post, we’re taking a closer look at zebra and quagga mussels, […]

When we think of invasive species in the Great Lakes basin, aquatic animals often jump to mind: zebra mussels coating a lake bottom, sea lamprey boring holes in fish, Asian carp leaping out of the water in droves as boats travel through waterways. Invasive plant species, however, can be just as impactful on ecosystems as […]

On November 19, 2019 GBBR held its first State of the Bay Conference at the Charles W. Stockey Centre in Parry Sound. Approximately 100 people were in attendance to hear about the latest research and monitoring findings on water quality, the lower food web, and fish communities. Attendees heard from knowledgeable presenters representing various government […]
In last month’s blog post, we dove into how the invasive sea lamprey entered the Great Lakes System, and the catastrophic effect they had on fish populations. While we touched on how rigorous control methods have reduced sea lamprey populations by up to 90 percent, going into exactly how sea lamprey control is done is […]

In 1919, improvements were made to the Welland Canal, a waterway that connects Lake Erie and Lake Ontario. The improvements widened the canal and allowed large ships to travel between the two; a feat that until then had been made impossible by Niagara Falls. With an effective connection between Lake Ontario and the rest of […]

The Georgian Bay Biosphere Reserve invites you to attend the State of the Bay Conference being held on November 19, 2019 at the Charles W. Stockey Centre in Parry Sound! This conference presents the latest research and monitoring findings on water quality, lower food web, and fish communities. The objectives of the conference are to […]
We are currently in a climate crisis. The world’s leading scientists have determined that greenhouse gases from human activity are causing the global climate to change and environmental changes are evident all the way to the local level. More on this at: https://stateofthebay.ca/the-ripple-effects-of-climate-change/ While the environmental issues caused by a changing climate are of great […]

We all know what algae is. We see it every summer in our lakes and rivers, whether it be as floating mats, delicate strands, or something to slip on getting into the water. Algae may seem like a nuisance to some, but these microorganisms are vitally important. They are at the base of our food […]
Last summer the Parry Sound 33 (PS33) forest fire swept the northern coast of the biosphere region, starting at Henvey Inlet First Nation and spreading to surrounding areas. Reaching almost 12,000 hectares, it was a force that left people worried for not only their homes, but for the plants and animals that also inhabit those […]
Algae is a summer constant, and a constant source of worry for many cottagers. The presence of algae in the Georgian Bay area is often seen as a sign that something is wrong. Whether it be a faulty septic system, or phosphorus pollution, people worry that the algae they are seeing are the result of […]
You’ve probably heard of the legacy of DDT and its effects on species such as the bald eagle. When this chemical was being produced and actively used in the mid 1900s, the eagles were poisoned when they consumed the contaminated fish. In turn, this chemical interfered with the birds’ ability to produce strong eggshells. As […]
When salt from our roads makes its way into the Bay or inland lakes, the salt dissolves into two separate ions – sodium and chloride. Chloride is a greater threat to aquatic ecosystem health. […]
With our cold Northern Ontario winters comes icy roads and consequently, road salt. Trucks travel up and down the highways spitting out these pellets of sodium and magnesium chloride hoping to melt some of the ice build-up. But what are the effects of this salty solution on our ecosystems? Are there any alternatives? […]
The world’s leading scientists have stated that humans are causing the climate to change. By increasing the amount of greenhouse gases in the atmosphere, we have raised the global temperature by 1°C since the industrial revolution. The new IPCC (Intergovernmental Panel on Climate Change) report released earlier this year urges us to keep global warming to a maximum of 1.5°C. Beyond this point, we will worsen floods, drought, extreme heat and weather events, and food shortages. […]
Georgian Bay is a nearly 15,000 square kilometers, making it almost the same size of Lake Ontario! Consequently, it is hard to study the Bay as one whole body of water. To understand water quality we use two regions of focus: the nearshore and the offshore. […]

Monarch Butterfly. Eastern Foxsnakes. Massasauga Rattlesnakes. Whip-poor-will. Bald Eagle. Blanding’s Turtle. Little Brown Bat. Lake Sturgeon. What do all of these species have in common? Not only are they iconic species that we can find in our Biosphere, but all of these are also species at risk of extinction. Eastern Georgian Bay is home to […]
Georgian Bay is warming, our local food web is collapsing, and invasive species are on the rise. With each passing decade, we make the ecosystems upon which we depend more vulnerable. Isn’t it time we stopped putting so much carbon dioxide into our own atmosphere? The most powerful computers on earth show that warmer winters […]

Since the Industrial Revolution, when we began burning coal and then oil, people have been changing the planet’s climate. According to NASA and the world’s scientists, burning fossil fuels and other human activities has increased the carbon dioxide (CO2) in the atmosphere from 280 parts per million to 400 parts per million in the last […]
When the United Nations launched the World Network of Biosphere Reserves in 1970, one of its main goals was to conserve landscapes, ecosystems, individual species and genetic variation. Core protected areas within a biosphere reserve, such as national and provincial parks, provide the physical space—or ecosystems—species need to thrive. In eastern Georgian Bay, we have […]

One of the best ways to study the state of Georgian Bay is to look at the fish community, and specifically whether each species of fish is naturally reproducing – or if the population is declining. Fish are a useful indicator of aquatic ecosystem health because they reflect changes in nutrients, prey availability, water quality […]
Many of us love hearing the call of a loon or seeing a majestic bald eagle. These species are the top of the food chain, relying on a healthy diet of fish. But what feeds the fish that they eat? Scientists are researching what they call “the lower food web” in Georgian Bay, and we […]
The home of the great blue heron, feeding grounds for rattlesnakes and fox snakes, and breeding habitats for numerous amphibians are all being threatened. These are the coastal wetlands of Georgian Bay and they are essential to a healthy environment. Unfortunately, wetlands across the world are at risk from shoreline modifications invasive species and from […]
Think about what makes life possible under water. Phosphorus is the “food” that microscopic plants and animals need to survive. As the foundation of our food web in Georgian Bay, phosphorus is an important nutrient for us to measure when we study the health of our ecosystem. You can imagine that there wouldn’t be many […]

Do you ever wonder about the state of Georgian Bay? How is the water and habitat for wildlife and fish? How is climate change affecting the Parry Sound area? In 2008, conservation groups asked the same questions and launched a research program that led to the first “State of the Bay” report in 2013 to […]
