Facts from harvest registration and growing old, in conjunction with other knowledge, is used in a mathematical populace model known as the Sex-Age-Eliminate (SAK) formulation. Info on the age composition from the buck harvest is used to estimate The proportion of adult bucks killed in the authorized hunt.
