The vast majority of people living in areas prone to wildfires听know they face risk, but they tend to underestimate that risk compared with wildfire professionals.

At the same time, they tend to over-estimate the importance of specific risk factors beyond their control -听such as the composition of vegetation on their property -听while giving less heed to those they can mitigate, such as replacing combustible siding with more fire-resistant materials.

Those are key findings of researchers from the 麻豆视频, the U.S. Forest Service Rocky Mountain Research Station, the U.S. Bureau of Land Management and the West Region Wildfire Council. The team鈥檚 findings, published in the journal Risk Analysis in June, are based on surveys of nearly 300 residents of Log Hill Village in southwestern Colorado鈥檚 Ouray County in 2012.

鈥淎 lot of natural听hazards research finds that people tend to overweight things they have pretty limited control over. But they are downplaying the risk of things they can do something about, such as creating a 鈥榙efensible space鈥� and what kind of siding they have,鈥� said James Meldrum, the study's lead author and a research associate in the environment and society program at the university鈥檚 Institute of Behavioral Science.

But identifying such gaps in perception may be able to help wildfire professionals better communicate risks and design incentives to get homeowners to better protect their properties.

鈥淭he reality is that there is not enough (wildfire) suppression to go around to protect every house that is out there,鈥� said Meldrum.

Overall, 93 percent of respondents answered听鈥測es鈥� when asked, 鈥淎re you concerned about wildfire risk affecting your current residence?鈥�

But expert and residential opinion differed significantly.

While 50 percent of residents rated their properties as being at 鈥渕oderate risk,鈥� professionals rated 65 percent as being at 鈥渉igh risk.鈥� Fifty-three听percent underrated their wildfire risk relative to the professionals, and 18 percent overrated risk.

Digging deeper, researchers gauged residents鈥� perception of specific risks in 10 categories, including risk from vegetation type on the property, the type of materials used for roofing, and questions regarding accessibility to firefighting teams and equipment, such as the visibility of the address number.

Residents鈥� perception of risk was less than that assessed by professionals for five attributes 鈥� address visibility, deck type, siding type, distance to hazardous vegetation and distance to other combustible hazards (such as propane tanks).

The professionals and residents rated risk roughly the same for number of roads accessing a property and distance to problematic topography, such as a steep canyon or ridge, and roof type.

In two categories, vegetation type and driveway width, residents reported higher risk perception than the professionals.

Paradoxically, residents tended to fret more about things they couldn鈥檛 change, such as the vegetation profile, than those they could, such as rebuilding a deck or cutting down trees near their homes.

鈥淎 lot of people do see the costs of being able to do the work themselves, and that stops them from doing it,鈥� Meldrum said. 鈥淭hey might want to, but when push comes to shove, they don鈥檛 necessarily do it.鈥�

He said the good news is that financial incentives offered by communities or governments have been fairly effective at persuading people to take action to protect their properties.

鈥淪o we can recognize these gaps for what they are and put money toward programs to help push people into taking action,鈥� he said.

That鈥檚 the idea behind Fire Adapted Communities, a coalition of government, business and nonprofit entities 鈥渃ommitted to helping people and communities in the wildland-urban interface adapt to living with wildfire and reduce their risk for damage, without compromising firefighter or civilian safety.鈥�

That campaign recognizes that wildfire is a natural part of many landscapes, and that the emphasis on suppression that held sway for most of the 20th century in the United States unintentionally resulted in fuel buildups that led to more听catastrophic fires.

鈥淭he idea that fire does belong on these landscapes is integral to the Fire Adapted Communities concept,鈥� Meldrum said. 鈥淭his is a big, top-down effort to get communities to recognize this, to take responsibility for the fact that they live in these places, and not be dependent on suppression. We want you to be OK if suppression can鈥檛 reach you.鈥�
