Areas of Critical Environmental Concern

As defined and authorized in the Federal Land Policy and Management Act of 1976 (FLPMA), an Area of Critical Environmental Concern (ACEC) is an area within the public lands where special management attention is required to protect and prevent irreperable damage to important historic, cultural, or scenic values, fish or wildlife resources, or other natural systems or processes, or to protect human life and safety from natural hazards.

Currently the Richfield Field Office Manages two ACECs. Relict vegetation was specifically identified as relevant and important in both ACECs. Management prescriptions for both ACECs include: allowing no uses that will cause irreparable damage to the relevant and important values; and reducing surface-disturbing activities within those areas, thereby protecting vegetation and relevant and important values. Restrictions will include closing the areas to OHV use; managing the areas as open to leasing subject to major constraints (NSO), making the areas unavailable for livestock grazing; and acquiring inholdings.
