Photos by joelsartore | Beavers are incredible engineers. The dams they build help maintain a healthy balance within environments by controlling runoff, erosion, and floods. Because of this, their actions not only directly benefit humans but also create crucial habitats for various plant and animal species. Photos taken newildliferehab, a center in Omaha, Nebraska, that saves injured and orphaned wildlife. To see more species featured in the Photo Ark, follow me joelsartore. #PhotoArk
