Great Lakes

Our Conservation Leaders

Lindsay Chadderton

Aquatic Invasive Species Director

Lindsay Chadderton has battled invasive rats and toads in Fiji and the Falkland Islands. He’s fought to protect New Zealand waters from the spread of marine seaweed, common carp, and a microscopic algae known as “rock snot.” And he’s worked to conserve the kakapo, a highly-threatened flightless parrot. Now, he’s using his expertise to fight invasive species right here in the Great Lakes.

As the aquatic invasive species director for the Conservancy’s Great Lakes Project, Lindsay leads a team working to stop the introduction and spread of Asian carp, Eurasian ruffe, and other invasive species in and around the Great Lakes. These non-native species enter the Great Lakes in a variety of ways and once they’re established can wreak havoc on native fish, wildlife, and local economies. In addition to developing new ways of keeping these aquatic invaders from spreading, Lindsay and his team also work to restore Great Lakes reefs and other habitats that native fish need to thrive.

Lindsay brings international expertise on invasive species – and how to stop them – to this role. Formally trained as an ecologist, he has worked at the local and regional levels with both urban and rural communities throughout his 30-year career. Prior to joining the Conservancy, Lindsay was part of the New Zealand Department of Conservation, a federal government conservation agency tasked with protecting and advocating for New Zealand’s biodiversity, recreational, and historic resources. He spent 17 years in a variety of roles across the organization.

“During this period, I worked in six countries providing conservation research or management advice,” Lindsay explains.

Lindsay has led or contributed to the development of many resource management plans and strategies, consulting with a wide variety of stakeholder groups, industry and management agencies. He has also co-authored 52 peer reviewed scientific publications, numerous technical management reports and strategies, and one book.  

What drew him to the Conservancy specifically was its mission.

“The Conservancy was the only U.S. organization that had a similar mandate to the agency I worked for in New Zealand,” he said.  “I liked that the Conservancy is focused on conserving nature and safeguarding it for future generations.”

Planning for the future is something Lindsay feels especially passionate about.

“I want to leave the planet, or at least the pieces I can influence, in a better, more sustainable condition for my son, and future generations,” Lindsay says. “I want to make sure he can enjoy the wonderful places in the world that I have had the privilege to see and work in.”
