2017年9月初，伊尔玛是近100年来袭击加勒比海北部的最强飓风。在21世纪，由于气候变化和内部气候变化，较强类型的热带气旋可能会增加频率。可以从这一极端事件中吸取经验教训，以预测红树林对这种加剧的反应。在这里，我们分析了圣马丁岛红树林造成的破坏。由于历史上的人类压力和最近的过度城市化，这个岛屿的红树林以前已经退化。森林调查和极高分辨率卫星图像的时间序列显示，大约80%的红树林面积被飓风破坏。结果突出了明显的森林恢复率。在大多数研究地点，大部分都观察到了早期和快速的恢复。然而，在骚乱发生14个月后，一些红树林仍然无法恢复。飓风前人为造成的生态系统退化被认为是控制森林缺乏恢复的主要因素。我们建议，面对这样的极端事件，人类退化的红树林将被削弱。我们主张保护和恢复红树林，以保证它们提供的所有宝贵的生态系统服务。
In early September 2017, Irma was the most powerful hurricane that struck the northern Caribbean over the last 100 years. In the 21st century, the stronger types of tropical cyclones will likely increase in frequency due to the climate change and internal climate variability. Lessons to anticipate the response of mangroves to this intensification can be learned from this extreme event. Here, we analysed damages caused in mangrove forests of the Saint Martin Island. Mangroves of this island were previously degraded due to historic human pressures and recent over-urbanisation. Forest inventories and time series of very high resolution satellite images revealed that approximately 80% of the mangrove area was damaged by the hurricane. Results highlighted distinct rates of forest recovery. Early and rapid recoveries were largely observed in most study sites. However, some mangroves were still unable to recover fourteen months after the disturbance. The human-induced degradation of the ecosystem prior to the hurricane is hypothesised to be the main factor controlling the absence of forest recovery. We suggest that human-degraded mangroves will be weakened in the face of such extreme events. We advocate to preserve and restore mangroves in order to guarantee all the valuable ecosystem services they provided.
