DES MOINES, Iowa (AP) – Gov. Terry Branstad has signed an executive order legalizing the use of lead shot in the hunting of doves, rescinding an action by the state Natural Resources Commission.  Branstad’s action today (Friday) allows dove hunters to use lead shot when the season begins in September.  The Iowa Natural Resources Commission last year approved a rule banning lead shot for dove hunting. The Legislature’s Administrative Rules Review Committee then agreed to postpone the rule to give the Legislature time to pass a law that would allow lead shot for dove hunting.  This year, the House passed a resolution, but the measure died in the Senate.  Opponents of dove hunting say the pellets contaminate the environment for other animals. Hunting groups say steel shot costs more and doesn’t work as well.
