With decades of experience in this sector, Wally shares his view on environmental stewardship in the US, and the work being done in stream and wetland restoration across North America.

David speaks with Tim Male, Founder and Executive Director of the Environmental Policy Innovation Center based in the US state of Maryland.

Having previously worked on environmental issues at the White House and held several roles in environmental policy at a range of US organisations, Tim shares his view of the biodiversity landscape in the US.
