Thank you for your report! Unfortunately nutria are a common sight in the Portland area and many other places in Oregon. Depending on the needs of the site and potential damage nutria are or may be causing, they are sometimes removed. If you have concerns about nutria at Grant Butte, you can contact Metro, who manages this park. There's also a link to some good information from Oregon Dept of Fish and Wildlife in the Resources section below.

Thank you,
Lindsey Wise
