Wyoming Game and Fish officials are advising black bear hunters who want to use bait for the upcoming bear seasons that the registration period for existing bear bait sites begins March 1st. Those who had bait sites registered in 2010 can register the same sites between March 1st and March 21st. Then, the registration period is closed from March 22nd through the 31st before being reopened for the issuance of unclaimed bait sites on April first. Hunters can renew existing bait sites by telephone, mail, fax, in person or through a representative. Bait sites are registered for the year and cannot be changed until the following year.
