On July 26, 2019, a human-caused fire three miles northwest of Lake Helena burned approximately 5,019 acres, including 4.5 miles of fenceline. 

Because emergency stabilization lacked funding at the time, Brandy Janzen, Butte Assistant Field Manager, executed a cooperative agreement with the Montana Conservation Corps (MCC) for labor costs to re-construct the priority portion of the burned fence. Work was scheduled for early April-May 2022, and the estimated cost was $11.50/ft.

Fire effects to range resources 

The fire burned about 4.5 miles of fence, damaging the wooden components of the fences, wire, corners, braces and cattle guards. Further, 428 Animal Unit Months (AUMs) were rested from livestock grazing for two full growing seasons to allow the rangeland resources to recover. Affected allotments include the Hilger Hills, Sieben and Doghair allotments. 

To maintain the integrity of the grazing systems and to keep the livestock of adjacent private landowners from entering and grazing the burned area during the rest/recovery period, the BLM retained funding to replace priority infrastructure. Ranchers with grazing permits on the allotments provided labor and equipment.

An Animal Unit Month (AUM) is the amount of forage required by one animal unit for one month. The Natural Resources Conservation Service (NRCS) uses 30 pounds of air-dry forage per day as the standard forage demand for a 1,000- pound cow and her calf (one animal unit). An AUM the use of public lands by one cow and her calf or their equivalent including but not limited to one horse, or five sheep or goats for a month.
