Alterations generated by intensified wildfire regimes are leading to unprecedented impacts in the supply of ecosystem services (ES). We investigated how a large wildfire affected the components of ES delivery (capacity, flow, and demand) in a fire-prone landscape. We selected a set of socio-ecologically and economically important provisioning ES and analysed temporal trends in and mismatches between ES flow and demand indicators over three spatial scales. Serotinous pine forests were the principal service providing units (SPUs) contributing to ES supply before fire. Fire interrupted their ES capacity, correspondingly reducing the ES flow of wood production, hunting, livestock, and mushroom harvesting for several years. Actual fire-driven losses in wood production were masked by the immediate removal and selling of the burned trees. We detected two new opportunities of ES delivery emerge as a result of post-fire natural vegetation dynamics that last until today: honey and resin collection. Finally, there were no spatial mismatches between ES flow and demand over time due to wildfire occurrence. These findings highlighted the need to promote the post-fire recovery of key SPUs, and identify new unforeseen opportunities of ES supply created by fire and by the natural post-fire dynamics of the vegetation, to, at least partially, reverse the losses.

野火对易发生火灾的海洋松树为主的森林中生态系统服务交付的影响

野火加剧导致的变化正在对生态系统服务 (ES) 的供应产生前所未有的影响。我们调查了大型野火如何影响易发生火灾的环境中 ES 交付的组成部分(容量、流量和需求)。我们选择了一组在社会生态和经济上具有重要意义的供给 ES,并分析了三个空间尺度上 ES 流量和需求指标的时间趋势和不匹配。有血清的松林是主要的服务提供单位 (SPU),在火灾前为 ES 供应做出贡献。火灾中断了他们的 ES 能力,相应地减少了木材生产、狩猎、牲畜和蘑菇收获的 ES 流量数年。木材生产中由火灾造成的实际损失被立即移除和出售被烧毁的树木所掩盖。由于火灾后的自然植被动态持续到今天,我们发现了两种新的 ES 交付机会:蜂蜜和树脂收集。最后,由于野火的发生,随着时间的推移,ES 流量和需求之间没有空间失配。这些发现强调需要促进关键 SPU 的火灾后恢复,并确定由火灾和植被的自然火灾后动态创造的 ES 供应的新的不可预见的机会,以至少部分地扭转损失。
