What did the Burrard Inlet look like in the past, compared to how it is now? What were the fishing, food source, and maritime resources there and how did this habitat change over time? UBC researchers sought to answer those questions, in a clear and interactive way.

In collaboration with Tsleil-Waututh Nation and West Coast Environmental Law, graduate student researchers in the Ocean Leaders Program at the Institute for the Oceans and Fisheries and University of British Columbia brought together research on factors of change in Burrard Inlet. Blending this information into an interactive "Story Map" webpage, they illustrate how factors such as infrastructure, fishing, climate, and maritime activities have impacted Burrard Inlet over the past 200 years, while also highlighting some exciting conservation and restoration projects.

Burrard Inlet has been home to Tsleil-Waututh Nation (The People of the Inlet) for thousands of years, long before European settlers came in the 1700s. The Nation "hunted, fished, and harvested abundant food in and around Burrard Inlet, including crabs, clams, mussels, oysters, fish, duck, deer, bear, elk, pheasant, berries, and other food and ," said Tsleil-Waututh Nation employee, Spencer Taft. Even today, the inlet is an important source of food, livelihood, and recreation for all the communities that live along its shores.

However, "the Inlet has experienced a lot of change over the past several hundred years, and this has impacted food production and put many of the plants and animals at risk," said Fanny Couture, a Ph.D. student, and one the Ocean Leaders Program research members who developed the website.

"The Inlet is an important place for recreation and food for all of the communities around Metro Vancouver, but it is often unsafe to swim in and eat from the waters," said Meaghan Efford, a Ph.D. student and another member of the Ocean Leaders Program research team. "Much of the habitat has, over the years, been lost to industrial and commercial activity. Protecting the Inlet from further damage would be beneficial to everyone along its coastline."
