Details from harvest registration and aging, coupled with other knowledge, is used in a mathematical inhabitants model known as the Sex-Age-Get rid of (SAK) formulation. Info on the age composition on the buck harvest is utilized to estimate the percentage of Grownup bucks killed throughout the lawful hunt. The SAK formulation brings together this estimate with information on the dimensions from the buck harvest to estimate the dimensions from the pre-hunt Grownup buck population.
