(a) The authorized officer may suspend active use in whole or in part on a temporary basis due to reasons specified in § 4110.3–3(b)(1), or to facilitate installation, maintenance, or modification of range improvements.

(b) When monitoring or documented field observations show grazing use or patterns of use are not consistent with the provisions of subpart 4180 of this part, or grazing use is otherwise causing an unacceptable level or pattern of utilization, or when use exceeds the livestock carrying capacity as determined through monitoring, ecological site inventory, or other acceptable methods, the authorized officer will reduce active use, otherwise modify management practices, or both. To implement reductions under this paragraph, BLM will suspend active use.
