To make the case that an animal needs protection under the Endangered Species Act, you have to prove that you seek to protect a distinct population of the animal.
And recent research appears to prove a distinction between Spring Chinook and Fall Chinook salmon native to the Klamath River.
Which may strengthen the case for protecting the troubled spring run under the ESA.
The Karuk Tribe recently filed notice of intent to request such protection for the fish.
Karuk Natural Resources Policy Advocate Craig Tucker and Tribal Council Member Joshua Saxon join us with reasons for the request.
