BOISE, Idaho (AP) — Federal land managers have agreed to restore information about grazing allotments not meeting rangeland health standards in 13 western states after a public lands advocacy group complained about the omission.

The U.S. Bureau of Land Management agreed the information covering 150 million acres is needed after Washington, D.C.-based Public Employees for Environmental Responsibility filed an administrative complaint. The group says the information helps the public measure the BLM's success or failure.

The BLM says it's currently working on restoring information omitted in the Rangeland Inventory, Monitoring, and Evaluation report for 2013 and subsequent years and should be down within six months.

The BLM says a mapping application failure resulted in the omissions that include whether overgrazing is causing an allotment to not meet acceptable standards.
