The World Wildlife Fund is working with local partners and ranchers to install artificial beaver dams in streams across the Northern Great Plains. The area’s ecosystem lost the benefits of beaver dams when the population of this aquatic creature was decimated in the mid-to-late 1800s for its fur.

Like their natural counterparts, artificial dams slow water flow and prevent harmful erosion, resulting in higher water tables, soil improvements, healthier plants and better habitats for wildlife. Areas with dams also recover more quickly from droughts.

Artificial dam construction borrows extensively from the beaver’s natural skills. Flexible branches from local trees are woven between wooden stakes and then packed with mud, sand, dirt, roots and plants. In a full-circle moment, a participating rancher spotted a beaver making a new home by expanding upon an artificial dam one year after it was installed.
