Beginning May 1, 2003, each captive cervid must be identified with two individual permanent identifications that are unique identifying numbers or marks and that can be a combination of any two of the following: ear tag, tattoo, microchip or other permanent identifier approved by the department in writing. Tags or marks shall be used to identify the herd premises and uniquely identify the individual animal. Licensed hunting preserves are exempt from this requirement except in regard to those cervids purchased or otherwise acquired after October 15, 2002.
