![]() ![]() (a) The global map (excluding Antarctica) illustrates spatial patterns of areas of 0–1500, 1500–3000 and ≥ 3000 m, (b) burned area (error bars stand for ± 1 SD of annual averages) and (c) changes in burned area at different elevations at 500 m intervals, (d) monthly variations in burned area (box-dot) in global high mountains, (e) major climatic parameters related to fire weather from August to December in high mountains: relative humidity, temperature, precipitation and volumetric soil water (0–7 cm). In this study, an abnormal increase in wildfires was identified during 2001–2021 and an unprecedented wildfire pattern was revealed in 2020 in global high mountains, on the basis of the burned area product derived from the moderate-resolution imaging spectroradiometer (MODIS).īurned area changes in global high mountains during 2001–2021. However, very few studies have yet focused on the evaluation of wildfire changes in high mountains (Westerling et al. Assessing the spatiotemporal variability of wildfires is, therefore, critical for understanding changes in climate and ecosystems in high mountains. 2021), global fire activities have in general been suppressed by human landscape management (Andela et al. ![]() Australia and the Amazon) have experienced extreme wildfire events recently (Boer et al. 2020), and is noticeable for those high-mountain biodiversity hotspots like the Himalayas and the Andes (Westerling et al. Vegetation fire is a crucial factor in shaping global biodiversity (Bowman et al. High mountains are sensitive to climate change due to their fragile ecological–environmental conditions (Rahbek et al. 2019) and have seen little influence of human activities (Klein Goldewijk et al. 1a), have extraordinarily rich biodiversity (Rahbek et al. High mountains, especially those with elevations higher than 3000 m above sea level (a.s.l.), account for less than 3% of the Earth's land surface when excluding the Antarctic (Fig. ![]()
