Three causes have been identified for the spiraling cost of wildfire suppression in the United States: climate change, fuel accumulation from past wildfire suppression, and development in fire-prone areas. Because little is likely to be performed to halt the effects of climate on wildfire risk, and because fuel-management budgets cannot keep pace with fuel accumulation let alone reverse it, changing the behaviors of existing and potential homeowners in fire-prone areas is the most promising approach to decreasing the cost of suppressing wildfires in the wildland-urban interface and increasing the odds of homes surviving wildfire events. Wildfire education efforts encourage homeowners to manage their property to decrease wildfire risk. Such programs may be more effective with a better understanding of the factors related to homeowners' decisions to undertake wildfire risk-reduction actions. In this study, we measured whether homeowners had implemented 12 wildfire risk-mitigation measures in 2 Colorado Front Range counties. We found that wildfire information received from local volunteer fire departments and county wildfire specialists, as well as talking with neighbors about wildfire, were positively associated with higher levels of mitigation. Firsthand experience in the form of preparing for or undertaking an evacuation was also associated with a higher level of mitigation. Finally, homeowners who perceived higher levels of wildfire risk on their property had undertaken higher levels of wildfire-risk mitigation on their property.
气候变化、过去野火扑救导致的燃料堆积,以及火灾多发地区的发展。由于几乎不可能采取措施来阻止气候对野火风险的影响,而且燃料管理预算跟不上燃料堆积的速度,更不用说扭转这种情况了,因此改变火灾多发地区现有和潜在房主的行为是降低城乡结合部野火扑救成本、提高房屋在野火事件中幸存几率的最有希望的方法。野火教育工作鼓励房主管理他们的财产以降低野火风险。如果能更好地理解与房主决定采取野火风险降低措施相关的因素,这类项目可能会更有效。在这项研究中,我们测量了科罗拉多州 Front Range 两个县的房主是否实施了 12 项野火风险缓解措施。我们发现,从当地志愿消防队和县级野火专家那里获得的野火信息,以及与邻居谈论野火,与更高水平的缓解措施呈正相关。以准备或进行疏散为形式的第一手经验也与更高水平的缓解措施有关。最后,那些认为自己的财产面临更高野火风险的房主,在自己的财产上采取了更高水平的野火风险缓解措施。
