What CPW is doing
Releasing ferrets since 2001, and since 2013 on the eastern plains in partnership with landowners. On one ranch near Lamar, CPW reported evidence of ferrets reproducing in the wild in 2024.CPWCPW
When fall 2025 spotlight surveys at another release site didn’t detect a single ferret, CPW started using drones for the first time to track newly released ferrets wearing radio collars. With Smithsonian researchers, it’s studying which species prey on the ferrets so it can explore non-lethal ways to reduce losses.CPW
