ECOLOGY:
Dammed If You Do, Damned If You Don't?
John Pickrell
CAMBRIDGE, U.K.--A major test of wills is shaping up over plans for the U.K.'s first large-mammal reintroduction: the European beaver (Castor fiber). Backers view bringing back the riparian engineer as a chance for Britain to get with the continental European mainstream and to put right a historical wrong. Critics, however, contend that in the 4 centuries since the beaver disappeared from the British Isles, its former habitat has become so degraded that it would be foolhardy to resurrect the species now.
