Dr. Sheila Colla is a pioneering conservation scientist and educator whose work bridges the gaps between pollinator health, urban ecosystems, and social justice. As one of the first scientists to quantitatively document the decline of a wild bee species, Dr. Colla played a pivotal role in the successful campaign to have the rusty-patched bumblebee listed as endangered in both Canada and the U.S. Her scientific expertise has been crucial in shaping pollinator advocacy, inspiring several campaigns that engage both citizens and policymakers alike.

In 2011, Dr. Colla co-founded BumbleBeeWatch.org, a citizen science initiative that has collected over 172,000 photo records of bumblebees across North America. This platform has empowered the public to actively participate in bee conservation and become informed about the vital role of pollinators, particularly in urban environments. Her efforts have not only transformed public understanding but have also earned her numerous accolades, including the Ontario Nature Education Award, the York University President's Research Impact Award, the Entomological Society of Canada’s C. Gordon Hewitt Award, and the American Library Association’s Outstanding Reference Source Award.

Dr. Colla is also a trusted voice in science communication, speaking on platforms such as CBC, Reuters, CNN, The Washington Post, and CTV National to reach millions of people. Her written work—including opinion pieces, articles, and books like The Bumblebees of North America: An Identification Guide and A Garden for the Rusty-Patched Bumblebee—has made pollinator conservation more relatable and actionable for Canadians, offering practical ways for people to support native pollinators right from their backyards.

Throughout her career, Dr. Colla has exemplified leadership in both science and advocacy, especially as a woman of colour in STEM. She is a role model for aspiring scientists and actively contributes to initiatives that promote diversity and equity in the field. Dr. Colla is dedicated to her outreach efforts, mentoring young ecologists and citizen scientists, and inspiring others to take part in the conservation movement.

Dr. Colla’s work demonstrates that science is not only about data—it’s about connecting people to the natural world and motivating them to protect it for future generations. Her approach underscores how science can be both impactful and accessible, solidifying her role as one of Canada’s leading advocates for pollinator and habitat preservation.
