Thank you for submitting the report. Nutria are common in parks around the region because they are often fed by humans. It is important for people to realize that nutria are rodents and potential reservoirs for a variety of diseases. The nutria page on the Center for Lakes and Reservoirs website at http://www.clr.pdx.edu/projects/ans/nutria.php contains information on nutria diseases. My contact information can also be found on this site if you have questions or would like further information.

I saw Nutria in Commonwealth Park in Beaverton, about 6 of them, about a month or two ago, before hearing about this program or knowing they were invasive. They were near the western end of the park, near the bathroom/outhouse near the play structure.
