Existing APR Zones 27, 29, 35, 63 – Age Class by Number

-712 + 114 = -598 (average number of bucks lost to harvest per year in the southern APR zones.)

- 116%

+ 7%

+ 88%


On 361 sq. miles of deer range, that’s <1/3 older age class buck per sq. mile harvested. (1 older buck ~>3 miles)

In Conclusion… Division of Fish & Wildlife supports QDM

on private lands where supported by quality habitat.

APR has positives & negatives:

Positives- harvest of older age class bucks increase.- increase in higher point classes

Negatives

- decrease in overall buck harvest- number of older age classes did not equal number ofyearlings saved.- increase in higher point classes did not equal decrease inlower point classes.
