r
pa a. The degree of use will not exceed 50% by weight of the current
season's growth of the key species when grazing occurs during any part
of a growing season. This would be from April 1st to October 30.
b. Under a planned grazing system where grazing occurs during the dormant
season grazing 60 percent of the annual growth by weight of the key
species would be permissible with concurrence of the District
Conservationist. Under no circumstances must this use contribute to
site deterioration. The date of dormancy will be November 1 through
March 31.
