The American beaver holds a prestigious place within Oregon's wildlife, standing as the state symbol, the mascot for Oregon State University, and a celebrated emblem on the reverse side of Oregon's state flag. Known for their remarkable engineering prowess, these beavers create habitats by constructing dams across streams and rivers throughout Oregon, offering critical ecosystem services and thriving in their natural habitat. Despite facing near extinction from fur trapping in past centuries, the resilience and concerted conservation efforts have led to the successful restoration of American beavers across many of Oregon's waters, heralding a promising future for these industrious creatures.

Beavers, often hailed as 'nature's engineers', play a pivotal role in enhancing biological diversity. Their skillfully constructed dams not only manage water flow but also create seasonal habitats for a wide array of wildlife, including insects, amphibians, reptiles, birds, fishes, and mammals. This intricate balance between beaver activity and habitat creation illustrates the profound impact these creatures have on Oregon's ecological health and biodiversity. The conservation of beavers and their habitats is thus critical, not only for sustaining their populations but for maintaining the ecological integrity of Oregon's waterways and surrounding environments.
