Wildfire & Mountain Sky

When the first European settlers came to America, they found not the pristine forests so commonly depicted by Albert Bierstadt, Frederic Church, and other Hudson River School painters, but rather they found a landscape marked by fire.

As fire chronicler Stephen Pyne (1997) has observed, human-set fires once cleansed the landscapes of North America, but today fires are absent from regions like the Northeast that formerly relied on them for farming and grazing; they have receded from the prairies, once near-annual seas of flame; and they have faded from the mountains and mesas, valleys and basins of the West.

 Fire is a natural component of the Gallatin-Madison range ecosystem. It is a driver of change that influences the overall structure of the forest, its species composition and its age class distribution. Fire helps drive the recycling of carbon and other nutrients in the soil, and stimulates the regeneration of fire-dependent, fire-adapted vegetation. For wildlife, fire removes the overstory of trees, causing openings that release grasses and forbs as well as creating snags and tree cavities for food, roosting, and nesting.

While wild fire is a natural process, it is commonly not welcome in conflict with humans, and the values society places on private lands, human-built structures, and desired natural resources (e.g., timber, recreation, water supply). While prescribed fire is a useful tool, in reality, its use is highly constrained due to risk of escaped fires threatening private and state land, as well as federal lands.

Two influences on today’s forest, and our ability to respond to wildfire, are noteworthy: 1) Smokey Bear and 2) the lure of building next to wildlands.


The first influence is a decades-long policy of attempting to prevent forest fire, as symbolized by Smokey Bear’s “Only You Can Prevent Forest Fires.” Though well-intentioned at the time, it is now widely acknowledged by researchers and managers that the policy of aggressive wildfire suppression has contributed to a decline in forest health, an increase in fuel loads in many forests, and wildfires that are more difficult and expensive to control (Donovan and Brown 2007). Fire suppression, combined with other influences like climate change, insect pests, and diseases, are contributing to vast changes in wildland vegetation with the result that landscapes are drier, less resilient, and more likely to burn once ignited. The number of large wildfires (>50,000 acres) has increased over the past 30 years, and wildfires are more intense than they were in the past.

The second influence is the lure of living next to wildland. It sounds idyllic, and more and more people are choosing to live in these natural areas -- referred to the wildland-urban interface (WUI). Unfortunately, as more people dwell in the WUI, fire management becomes more complex and the costs to fight wildfires and protect homes and human lives has risen sharply as a result. Firefighters are forced to fight wildfires based on private property and structures rather than the best way to contain fire or guide the actual fire -- adding millions of dollars in cost and increased risk to responding fire crews. Slowly efforts are building to incentivize private landowners to become ‘fire-safe,’ to initiate hazardous fuels reduction projects and increase landowner’s ability to defend structures and increase firefighter safety.

But the question is not if a fire event will occur, but rather a question of when, where, and to what extent. Forest and fuels management cannot prevent fire, but it can greatly influence its behavior, intensity, and extent.

The effects of two fires on Mountain Sky Guest Ranch are plain to see.



Big Creek Wild Fire, July-August 2006.
 A lightning strike on a power pole within State Section 16 started the fire. On July 29, 2006, it was 97 degrees and 9 percent humidity. The fire was promptly reported and managed by two U.S. Forest Service incident management teams and several local fire teams. Full perimeter control was used on the north, south and east sides where homes and private land are present.  On the west side, where there were safety concerns and no human values at risk, very limited action was taken. The fire burned a total of 14,000 acres, 6,500 acres of national forest and 7,500 acres of private and state land.  It was declared controlled on October 19, 2006 at a cost of approximately $3 million. On Mountain Sky Guest Ranch, the fire burned some 1,720 acres in the north-central/Dry Creek area.

 “I remember a thunder storm on Wednesday, and high winds. Evidently a lightning strike smoldered till the wind on Saturday ignited it. We sat down for dinner about the same time that the wranglers turned out. Looking up from the picnic tables behind the main lodge, we saw a huge plume of smoke northeast of the upper ranch. The wranglers brought the herd back down and sent them to the lower ranch. The decision was made to evacuate the ranch. And we did.” Randy Venteicher, MSGR Head of Maintenance

Big Creek Prescribed Burn (March 2004, September 2008)
The Big Creek prescribed burns were authorized by the Gallatin National Forest, Paradise Valley Fuels Management and Prescribed Burning Project Decision Memo, on April 7, 2003.   The first prescribed burn, aimed at treating a ≈430-acre area (map), was implemented during the last week of March 2004.  Due to the fact that objectives were not achieved with this burn, the area was burned again in September 2008.  The 310-acre burn required about 130 acres of juniper slashing in 2007.  The burn was accomplished in a prescription burn window on September 14-15, 2008. In 2010, the riparian area between the upper bridge and the Big Creek Ranger Cabin was burned to reduce conifer encroachment and stimulate willow sprouting. Overall project goals were:

1.       Reduce conifer encroachment on grass and sagebrush meadows and aspen stands
2.       Maintain area with their natural fire occurrence and severity
3.       Public and firefighter safety during wildfire events
4.       Allow fire to play its natural role in the HPBH Wilderness Study Areas
5.       Provide and/or maintain existing defensible spaces within the drainage to facilitate fire suppression tactics and staging areas during wildfire events
