BLOG: Beavers: A Potential Missing Link in California’s Water Future

On California’s central coast, a region that usually receives drenching rainfall or fog for most of the year, some forests are now as arid as a desert. Streams that once ran at least at a trickle through summer have vanished in the ongoing drought, and environmentalists and fishermen fear that local salmon will disappear if climate conditions don’t improve.

The landscape desperately needs rain. It could also use beavers, according to ecologists who say the near eradication of Castor canadensis from parts of the West in the 19th century has magnified the effects of California’s worst dry spell in history.
