June 3, 2013 – The Service proposed to designate a mere 1,110 acres of critical habitat for the endangered Salt Creek tiger beetle in Nebraska's Lancaster and Saunders counties. The decision stands in sharp contrast to a 2005 recommendation by scientists that 36,000 acres of habitat needed to be protected to ensure the recovery of the beetle.
