Beavers accomplish long-stalled conservation plan on former army site, sparing crayfish and taxpayers alike

Beavers have saved Czech taxpayers $1.2m (£1m) by flooding a protected former army training site where a long-stalled dam was planned.

Officials had hoped to build a barrier to shield the Klabava River and its population of critically endangered crayfish from sediment and acidic water spilling over from two nearby ponds. As a bonus it would turn a part of this protected area south of the capital, Prague, into a nature-rich wetland.
