Info from harvest registration and getting old, as well as other information, is Employed in a mathematical population product called the visit Sexual intercourse-Age-Get rid of (SAK) formulation. Info on the age composition in the buck harvest is utilized to estimate the percentage of Grownup bucks killed throughout the lawful hunt. The SAK formula brings together this estimate with info on the size with the buck harvest to estimate the size with the pre-hunt Grownup buck population.
