BLM Completes Mosier Fuels EA

The Bureau of Land Management (BLM) Buffalo Field Office (BFO) has completed an environmental assessment (EA) addressing hazardous fuels mitigation treatments in the Mosier Gulch area.

Mosier Gulch is located west of Buffalo, Wyoming along US Highway 16 and Clear Creek corridor. The planning area includes the Elk Ridge subdivision, other residences, and telecommunication facilities that adjoin or are intermingled with wildland fuels. These areas of human development that adjoin wildland fuels are defined as wildland urban interface (WUI) communities. BLM and other interagency fire management cooperators have placed a high priority on reducing hazardous fuels in WUI communities.

According to BLM fuel specialist Kristi Bulock, “A wildland fire that occurred in the area early this spring demonstrated how quickly fire could spread in the fuels and steep south-facing slopes that occupy much of the area. The Shooter Fire spread rapidly over 10 acres even though fuels in the area still retained some moisture from snowmelt. Had this fire occurred under more extreme conditions such as are typical in the summer, it would have been very difficult to contain.”

The EA analyzes impacts to the human environment associated with BLM’s proposal to reduce hazardous fuels that were recommended in a hazardous fuels assessment and mitigation report.

Proposed fuel reduction treatments include creating fuel breaks by removing and/or thinning forest vegetation and conducting prescribed fire. Prescribed fire treatments will occur over a period of several years and primarily target removal of surface fuels within the ponderosa pine forest.

Before BLM conducts the burns, a prescribed fire plan will be prepared that specifies how, when, and where the burns will take place. The plan will include prescriptions for conducting both broadcast and slash pile burning within the planning area. BLM fuels specialists will evaluate multiple factors that influence fire behavior such as temperature, relative humidity, wind speed, slope, aspect, fuel type and conditions, and forecasted weather. The plan establishes the personnel and the amount and types of equipment required to conduct the burn and contain the fire within the planned perimeter. The prescribed fire plan will also include agreements or permissions for burning any non-BLM administered land.

In addition to the BLM’s preferred alternative to implement the treatments recommended in the hazardous fuel mitigation plan, BLM considered and analyzed the effects of not changing the current management (the no action alternative). BLM’s Buffalo Field Office Manager, Duane Spencer, states “I have decided to implement the preferred alternative because it best meets BLM’s resource management goals and will help reduce risk from wildland fire to the public.”

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
