Hunters in Wyoming will need a 2018 conservation stamp as of Monday.

The 2017 stamp expires on Dec. 31, even for those with hunting licenses that are valid into next year. The stamps can be purchased at Wyoming Game and Fish offices around Wyoming or online.

Applications for many resident and non-resident Wyoming big-game hunting licenses will also open on Tuesday, January 2.

Those include licenses for deer, elk, bighorn sheep, antelope, turkey mountain goat, and bison.
