Researchers use “beaver mimicry” to copy how beaver dams change waterways. Interest has grown because climate change threatens rivers, streams and nearby lands in places such as the Pacific Northwest.
A team at a university reviewed many scientific studies and found several benefits. The work reports cooler summer water, more water storage, better flood-plain connections and more plants and animals. Some projects build simple structures and other projects try to attract beavers back to streams.
People who practice these methods now often work with local groups. The researchers say more study is needed to know how well the results apply in different places.
