Recruiting Beavers

Wilderness workers are recruiting beavers for habitat restoration.  Beavers are a keystone species for two reasons.  First, they're fussy about water quality: if you have beavers, then you know that your water is pretty good.  Second, they have a huge impact on the whole ecosystem around them.  By damming creeks, they create ponds that establish habitat for many more creatures than a small trickle would offer.  Just putting back the beavers that have been extirpated from many places can go a long way toward fixing the damage.
