25 CFR § 161.204 - How are carrying capacities and stocking rates established?

(a) BIA, with the concurrence of the Navajo Nation, will prescribe, review and adjust the carrying capacity of each range unit by determining the number of livestock, and/or wildlife, that can be grazed on the Navajo Partitioned Lands without inducing damage to vegetation or related resources on each range unit and the season or seasons of use to achieve the objectives of the agricultural resource management plan and range unit management plan.

(b) BIA, with the concurrence of the Navajo Nation, will establish the stocking rate of each range or management unit. The stocking rate will be based on forage production, range utilization, the application of land management practices, and range improvements in place to achieve uniformity of grazing under sustained yield management principles on each range or management unit.

(c) BIA will review the carrying capacity of the grazing units on a continuing basis and, in consultation with the Grazing Committee and affected permittees, adjust the stocking rate for each range or management unit as conditions warrant.

(d) Any adjustments in stocking rates will be applied equally to each permittee within the management unit requiring adjustment.
