The environmental and socio-economic impacts of wildfires are foreseen to increase across southern Europe over the next decades regardless of increasing resources allocated for fire suppression. This study aims to identify fire-smart management strategies that promote wildfire hazard reduction, climate regulation ecosystem service and biodiversity conservation. Here we simulate fire-landscape dynamics, carbon sequestration and species distribution (116 vertebrates) in the Transboundary Biosphere Reserve Gerês-Xurés (NW Iberia). We envisage 11 scenarios resulting from different management strategies following four storylines: Business-as-usual (BAU), expansion of High Nature Value farmlands (HNVf), Fire-Smart forest management, and HNVf plus Fire-Smart. Fire-landscape simulations reveal an increase of up to 25% of annual burned area. HNVf areas may counterbalance this increasing fire impact, especially when combined with fire-smart strategies (reductions of up to 50% between 2031 and 2050). The Fire-Smart and BAU scenarios attain the highest estimates for total carbon sequestered. A decrease in habitat suitability (around 18%) since 1990 is predicted for species of conservation concern under the BAU scenario, while HNVf would support the best outcomes in terms of conservation. Our study highlights the benefits of integrating fire hazard control, ecosystem service supply and biodiversity conservation to inform better decision-making in mountain landscapes of Southern Europe.

山区农田保护和消防智能管理共同减少火灾隐患,增强生物多样性和碳固存

预计在接下来的几十年中,无论分配给灭火的资源增加如何,野火对环境和社会经济的影响将在整个欧洲南部增加。这项研究旨在确定能促进减少野火危害,气候调节生态系统服务和生物多样性保护的智能消防管理策略。在这里,我们模拟了跨界生物圈保护区Gerês-Xurés(西北部伊比利亚)的火地景观动态,碳固存和物种分布(116个脊椎动物)。我们根据以下四个故事情境,设想了由不同管理策略产生的11种情况:照常营业(BAU),扩展高自然价值农田(HNVf),Fire-Smart森林管理以及HNVf加Fire-Smart。火灾景观模拟显示,每年燃烧面积增加了多达25%。HNVf地区可能会抵消这种日益增加的火灾影响,尤其是与火警策略结合使用时(在2031年至2050年之间最多减少50%)。Fire-Smart和BAU方案的固碳总量达到最高估计值。在BAU情景下,预计1990年以来受保护物种的栖息地适宜性下降(约18%),而HNVf将在保护方面支持最佳结果。我们的研究强调了将火灾隐患控制,生态系统服务供应和生物多样性保护相结合的好处,从而可以更好地指导南欧山区的决策。Fire-Smart和BAU方案的固碳总量达到最高估计值。在BAU情景下,预计1990年以来受保护物种的栖息地适宜性下降(约18%),而HNVf将在保护方面支持最佳结果。我们的研究强调了将火灾隐患控制,生态系统服务供应和生物多样性保护相结合的好处,从而可以更好地指导南欧山区的决策。Fire-Smart和BAU方案的固碳总量达到最高估计值。在BAU情景下,预计1990年以来受保护物种的栖息地适宜性下降(约18%),而HNVf将在保护方面支持最佳结果。我们的研究强调了将火灾隐患控制,生态系统服务供应和生物多样性保护相结合的好处,从而可以更好地指导南欧山区的决策。
