Summary

Beavers have long been considered pests by landowners and government agencies. But now, many are starting to embrace them. Today on the show, Host Aaron Scott tells Host Emily Kwong how these furry ecosystem engineers are showing scientists a way to save threatened and endangered salmon and steelhead.

Watch the video Aaron filmed with Oregon Field Guide about beavers and stream restoration. For more videos check out Oregon Field Guide.

throw back.

As far as fishing goes, this kind of sounds like cheating, but I'm guessing these scientists
