Fawn to doe ratios collected in late summer give info on fawn recruitment and survival and they are made use of being an enter in the components for once-a-year deer herd abundance estimation.
The Grownup buck population is then expanded to your entire inhabitants applying estimates of the amount of does for each buck and the quantity of fawns per doe while in the pre-hunt populace. The overwinter deer population for every DMU is determined by subtracting the harvest with the pre-hunt populace estimate.
