Bob The Beaver

Meet Bob. 
Bob is a beaver. 

Beavers and their dams are common sights along creeks in Oregon. Beaver activity can create diverse habitats and homes for many animals, including birds, fishes, and dragonflies. The USGS are studying beaver dams and ponds in Portland, Oregon, to understand how they affect the amount and quality of water in urban streams. Insights from the study will highlight the effects and benefits associated with beaver dams and ponds in urban streams so that land managers can make strategic management and habitat restoration decisions based on science.
