Threats to Wilderness From Fire Suppression
Dropping retardant, like that being used in the Lava Beds Wilderness, is one fire suppression technique.
Despite running counter to scientific research and management goals to preserve both the natural and untrammeled qualities of wilderness, fire suppression has been the dominant fire management strategy in wilderness. As of 1998, only 15% of wilderness areas--excluding Alaska where fire use is more widespread--had approved fire plans that allow some natural ignitions to burn and even these areas continue to suppress many natural ignitions. Parsons also reported that between 1988 and 1998, even in the Bob Marshall Wilderness--the 5th largest wilderness in the lower 48 states and which has a progressive natural fire program--the average number of natural ignitions permitted to burn dropped by over half, the average size of natural fires decreased by 75%, and only 19% of all eligible lightning fire starts were permitted to burn.
Firefighters monitor the Bonita Fire, a management-ignited prescribed fire, in the Chiricahua National Monument Wilderness.
As a result of the 1988 fires, all wilderness fire programs were suspended pending a national review of fire policy. Two years later a public opinion survey revealed that 55% of Montana/Wyoming respondents and 48% of respondents living elsewhere supported a controlled burn policy, yet many respondents were illiterate about wildfire and its effects. Decades later, research suggests that fire use stigmas still exist. Although a 2004 study in Montana's Bob Marshall, Great Bear and Scapegoat wildernesses indicated that two-thirds of visitors felt natural ignitions in wilderness were desirable, a comparable assessment in the same area a year earlier, during a high fire season, showed that only 49% of visitors felt natural ignitions in wilderness were desirable.
The following reasons besides public sentiment may also perpetuate fire suppression: The small size of many wilderness areas results in natural ignitions outside of wilderness being suppressed before they can burn into wilderness; with increases in settlement in the wildland urban interface, the risks of fire escaping onto adjacent lands, unnaturally intense fires burning as a result of unnatural fuel loads, and unacceptable smoke impacts to surrounding areas are also very real.
In some cases, management-ignited fire may be an alternative to natural fire. However, although management-ignited fire may increase naturalness, it does so at the expense of wildness because it involves human manipulation of the wilderness landscape. As such, management-ignited fire is not always desirable. The same 2004 study researching Montana wilderness visitor opinions about natural fire found, for example, that respondents were split over the acceptability of management-ignited fire, with slightly over half indicating they would accept management-ignited prescribed fires in wilderness. Management-ignited fire is also not always feasible. Many of the same problems facing the reintroduction of natural fire also prevent management-ignited fire use, including the small size of many wildernesses, their proximity to urban areas, air quality concerns, and excess fuel buildup from past suppression efforts.
