Occurrences of vascular plant on algific talus slopes in South Korea

Algific talus slopes are characterized by locally detected unique micrometeorological phenomena such as cold air blowing or water getting frozen during summer and warm wind blowing during winter in a hole or crack on the rock. It is thus known that rare plants and plants that are uncommon in the environments at close proximity to humans are widely distributed on the algific talus slopes. Notably, as the habitats of polar and alpine plants that naturally grow in low temperature regions are being continuously reduced due to global warming or climate change, the micrometeorological phenomena on algific talus slopes, where low temperature is maintained even in summer, are critical for providing a refuge for plants sensitive to high temperatures and for the conservation of rare and endangered species. This study was conducted to rediscover the phytogeographic values of algific talus slopes by investigating the distribution of five plant types across 25 algific talus slopes as the specific areas of forest biodiversity. Vascular plants were investigated in each season during April 2016 to November 2021. We share the data of the sample collected here.

冰蚀坡脚地带以其独特的局地微气象现象而著称，如夏季冷风劲吹或水结冰，以及冬季暖风在岩石的孔洞或裂缝中吹拂。因此，众所周知，稀有的植物以及那些在人类居住环境附近不常见的植物在冰蚀坡脚地带广泛分布。值得注意的是，随着全球变暖或气候变化导致极地和高山植物的自然栖息地不断缩减，即使在夏季也能保持低温的冰蚀坡脚地带的微气象现象，对于为对高温敏感的植物提供庇护以及珍稀和濒危物种的保育至关重要。本研究旨在通过调查25个冰蚀坡脚地带五种植物类型的分布，作为森林生物多样性的特定区域，重新发现冰蚀坡脚地带的植物地理学价值。在2016年4月至2021年11月期间，对维管植物在每个季节进行了研究。我们在此分享所收集的样本数据。
