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.
