Bison Management 13
In the early years, bison were identified with metal eartags. Along with the eartag number, the animal's age, gender, weight, height, vaccination data and test results were documented. In the mid-1980's, all previous bison data was entered into a computer database. Data was recorded by hand during the roundup, and then manually entered into the database. This was time consuming, and in the event of a bison loosing an eartag, the corresponding data was lost.
