ST. PAUL— An environmental group has put the Minnesota Department of Natural Resources on notice that it plans to sue the agency for failing to protect Canada lynx from trappers.

The Center for Biological Diversity filed a 60-day notice on Wednesday as required by federal law before it can file a lawsuit to try to force the state to follow the Endangered Species Act.

The notice says the state has failed to comply with a 2008 federal court order that’s meant to protect lynx from being caught by trappers seeking other species.
