摘要

随着人类人口的增长和人为变化的加剧,代价高昂的野外火灾越来越多地影响着农村和公私交界地带的景观。气候变化、历史上的火灾抑制以及生物入侵正在增加全球系统的火灾风险。在一个辖区引发的火灾可能会跨越所有权边界蔓延,因此,景观尺度的火灾管理和规划需要了解不同辖区的火灾应对和管理情况。为了阐明土地所有者对火灾管理的态度与其过去野火经验之间的关系,我们结合了来自烧伤严重程度监测趋势(MTBS)数据库的地理空间野火数据和来自美国西部三个以国家公园为中心的生态系统中 586 个私人土地所有者的调查回应数据。我们的目的是研究土地所有者对其土地、邻居、公共机构和火灾本身的态度是否与(a)他们的地块是否经历过火灾,以及(b)最近一次火灾事件的范围和严重程度以及火灾发生后的时间有关。我们发现,受访者表示他们对火灾进行管理的程度与他们的地块是否在土地保有权期间发生过火灾有关,如果在土地保有权之前发生过火灾,则与他们获得土地后两年内是否发生过火灾有关。对于经历过火灾的受访者而言,他们对野火的关注程度、与邻居和公共机构的互动以及对其土地对更广泛的经济或自然系统所作贡献的看法都与火灾发生后的时间有关。此外,被烧毁的总面积和烧毁面积中严重程度较高的百分比与火灾发生后的时间相互影响,从而预测受访者的态度和看法。我们的研究结果表明,过去的个人经历对于塑造私人土地管理者的关系和观点以及他们在当前火灾管理中投资的可能性非常重要。

Experiences with wildfire are associated with private landowners’ management decisions, relationships, and perceptions of risk

As human populations grow and anthropogenic change increases, costly wildland fires increasingly affect rural, public–private interface landscapes. Climate change, a history of fire suppression, and biological invasions are increasing fire risk in systems worldwide. Fires that ignite in one jurisdiction can spread across ownership boundaries, with the result that landscape-scale fire management and planning requires understanding differential fire response and management across jurisdictions. To illuminate relationships between landowner attitudes and fire management and their experience with past wildfires, we combined geospatial wildfire data from the Monitoring Trends in Burn Severity (MTBS) database and survey response data from 586 private landowners across three national park-centered ecosystems in the American West. We aimed to examine whether landowners’ attitudes toward their land, neighbors, public agencies, and fire itself were related to (a) whether they had experienced fire on their parcels, and (b) the extent and severity of the most recent fire event and the time elapsed since that fire. We found that the degree to which respondents reported that they manage for fire is related to whether a fire had burned on their parcels during their land tenure or, if prior to their tenure, within two years of their acquisition of the land. For those respondents that had thus experienced fire, their level of concern about wildfire, interactions with neighbors and public agencies, and perception that their land contributed to a broader economic or natural system were all related to the time that had elapsed since the fire. Furthermore, total burned area and the percent of the burn that was high severity interacted with time since fire to predict respondents’ attitudes and perceptions. Our findings illustrate the importance of personal past experiences in shaping private land managers’ relationships and viewpoints, as well as the likelihood that they invest in current fire management.

期刊介绍: Landscape and Urban Planning is an international journal that aims to enhance our understanding of landscapes and promote sustainable solutions for landscape change. The journal focuses on landscapes as complex social-ecological systems that encompass various spatial and temporal dimensions. These landscapes possess aesthetic, natural, and cultural qualities that are valued by individuals in different ways, leading to actions that alter the landscape. With increasing urbanization and the need for ecological and cultural sensitivity at various scales, a multidisciplinary approach is necessary to comprehend and align social and ecological values for landscape sustainability. The journal believes that combining landscape science with planning and design can yield positive outcomes for both people and nature.
