Dr. Doug Tozer was honoured with a Conservation Award from Ontario Nature in early December 2025, spotlighting decades of quiet, meticulous work that has transformed how we understand and protect wetlands and the birds and frogs that depend on them.
His story is not just about scientific excellence, but about leadership, mentorship, and a rare gift for making complex science understandable for the public.
For more than 30 years, Doug has immersed himself in marshes, bogs, and shorelines, designing and implementing monitoring programs for birds, frogs, and their habitats across the Great Lakes, and beyond. As Director of Waterbirds and Wetlands at Birds Canada, he leads multiple high-profile science-based programs, overseeing more than a thousand volunteers and staff who collect data that can be used to guide conservation action.
Doug’s work is grounded in rigorous field science and advanced analysis of long-term data, including topics like habitat relationships, detection probabilities (how likely you are to find something that is actually there), population trends, and wetland health. This sustained effort has helped identify priority areas for conservation, evaluate restoration success, and track how wetland wildlife is responding to a rapidly changing climate and landscapes.
Doug is a leader on large-scale wetland monitoring programs that shape restoration strategies and policy across the Great Lakes region. Much of this impact flows from his leadership of the Great Lakes Marsh Monitoring Program and the Great Lakes Coastal Wetland Monitoring Program, which provide long-term, standardized data that decision-makers trust and utilize research on marsh-breeding birds in southern Ontario has directly informed best management practices for wetland restoration, benefiting species of conservation concern such as the Least Bittern and Black Tern by clarifying what healthy habitat looks like on the ground.
Doug has also published influential studies on issues like invasive phragmites control and the effects of changing water levels, giving wetland managers concrete guidance on how to restore degraded marshes and keep them resilient.

Conservation leadership is measured not only in papers and policies, but in people, and this is another area where Doug excels. Over his career, he has mentored roughly 20 graduate students and postdoctoral fellows, helping them develop the technical skills, scientific curiosity, and sense of responsibility needed to carry waterbird and wetland conservation forward. He also represents Birds Canada on collaborative bodies such as the international Loon and Diver Research Working Group (which he co-chairs) and the Ontario Eastern Habitat Joint Venture Steering Committee, where he works with partners across sectors to align science, funding, and on-the-ground action. It isn’t unusual to see or hear Doug sharing his knowledge with onsite wetland managers – ensuring a direct link between science and conservation. By fostering collaboration and building capacity in others, he ensures that the impact of his work extends far beyond his own projects or publications.
Doug continues to grow his mentoring activities, bringing wetland science to a larger community as he hosts MarshWatch – Great Lakes edition in 2026. With this project, Doug will share his love of wetlands with those less familiar, introducing beginners and new professionals to marshes and wetland-dependent birds and frogs, mentoring their species ID skills, and giving them a chance to “wet their feet” on marsh data collection through the NatureCounts app.

Doug’s leadership is equally evident in how he shares science with the public. In addition to nearly 60 peer-reviewed publications as well as other reports, he regularly writes popular articles, speaks on podcasts (see “Do birds have feelings?” and “Did a chickadee steal my hotdog?”), and steers documentaries, translating specialized research into compelling stories about loons, marsh birds, and the future of Great Lakes wetlands. Whether speaking at events, contributing to outlets like BirdWatch and Birding Magazine, or acting as an engaging MC with a well-timed pun, he tailors his message to each audience while keeping the core science accurate and clear. That ability to bridge rigorous research and public engagement is a key reason his work has galvanized volunteers, inspired volunteer scientists, and built broader support for wetland conservation and protection.

Ontario Nature’s Conservation Awards celebrate people and organizations whose efforts safeguard wild species and spaces across the province, and Doug’s recognition in 2025 underscores how essential wetlands are to Ontario’s biodiversity. By documenting long-term trends, guiding restoration, and championing evidence-based policy, he has helped ensure that they remain vibrant homes for birds, frogs, and countless other species.
Doug’s award is, in many ways, a celebration of the thousands of volunteers, students, and colleagues he has inspired to pull on rubber boots, head into the cattails, and turn data into good conservation decisions. It is also a reminder that thoughtful, sustained, and collaborative science can change the trajectory of entire ecosystems—and that Ontario’s wetlands and those of the rest of the Great Lakes are in far better shape because of Dr. Doug Tozer’s leadership.
My role with Birds Canada is to unravel patterns and processes driving avian population dynamics using citizen-science dataset collected by bird enthusiasts from across Canada. It is a privilege to mobilize these hard-earned datasets to help resolve key conservation challenges facing avian populations.
I am an avid supporter of conservation, habitat stewardship, and biodiversity, in the strength of grassroots community actions, and that each individual can make a difference. I spent my childhood in Long Point, Ontario next to the Big Creek National Wildlife Area. There I formed a great love for boating, wetlands, wildlife, and all things aquatic. I hold an H.B.Sc. in Wildlife Ecology and Environmental Studies from the University of Guelph, a M.Sc.F in Wildlife Management from Lakehead University and Volunteer Management accreditation from Humber College.

Birds Canada science has helped attract millions of dollars in recent funding to restore hundreds of hectares of threatened Great Lakes coastal wetlands for birds. Read on to see how data from our Great Lakes Marsh Monitoring Program and science-based recommendations from our Long Point Waterfowl and Wetlands Research Program have been critical for making this happen.
More than a century of conservation efforts paid off this spring, when a pair of Piping Plovers established a nest at Long Point for the first time since 1977. For nearly 50 years, birders, scientists, and nature lovers have eagerly awaited the return of nesting Piping Plovers to the Canadian shores of Lake Erie. Read on to learn just how significant this return is, and why it gives us hope for the future.
Strong partnerships are at the heart of effective bird conservation, and the growing relationship between Timiskaming First Nation (TFN) and Birds Canada embodies that spirit.
