Response History
I have photos that I am unable to attach using the feature on this form. I can e-mail them to an e-mail address. Thank you.
Thank you for submitting the report. The animals you are seeing are nutria, an invasive, semi-aquatic mammal native to South America. Unfortunately, nutria are now common in the Portland metro area. In fact, I have been to the Tanasbrook location and am aware of the nutria population there.
It is important to realize that nutria are potential reservoirs for a variety of diseases that can be transferred to other species, including humans in some cases. Nutria can also become aggressive on occasion, so please encourage people not to feed the nutria if feeding is currently happening.
The nutria page on the Center for Lakes and Reservoirs website at http://www.clr.pdx.edu/projects/ans/nutria.php contains more information on nutria impacts if you are interested. My contact information can also be found on this site if you have questions or would like further information.
Thanks again for your efforts!
