Hi Janeen, thank you for your response. It is very likely the species you heard is the Pacific tree frog, which lives in all 8 ecoregions in Oregon. This frog is a very common species of chorus frog, and is very commonly found and heard in the desert. They breed from November through July, so it's very likely you heard one or more breeding males, which can be very loud. There's numerous websites with Pacific tree frog sounds - perhaps you could listen to them and see if the sound was similar. Here's a great one - http://www.sdnhm.org/fieldguide/herps/video_treefrog.html
But just remember that in the middle of the desert, the sound is incredibly amplified. A chorus of male frogs can sound deafening at times, which may have been why you thought it was the loud invasive coqui tree frog.
Thank you again for your report - we appreciate your help in watching for invasives! Lisa DeBruyckere, Oregon Invasive Species Council Coordinator
