Species-rich montane lawn companies on avalanche railways of the Gesäuse National Park (Austria)

The aim of this study was to gain insights into the importance of avalanche railways for biodiversity. In the Gesäuse National Park (Steiermark, Austria), 16 plant populations in three selected avalanche lanes were examined in plant sociology, characterised vegetation ecology and documented with vegetation table, soil analysis data and topographic parameters. In addition, an inventory of the butterflies was carried out. The diversity of plant species was assessed with different diversity indices. The causes of the species richness in the examined avalanche tracks are discussed.本研究旨在深入探究雪崩通道（avalanche railways）对生物多样性的重要性。研究区域设于奥地利施蒂利亚州的格萨乌斯国家公园，针对选定的3条雪崩廊道内的16个植物种群开展植物社会学调查，对其植被生态特征进行表征，并通过植被样表、土壤分析数据及地形参数完成系统性记录。此外，本研究还完成了蝴蝶类群的物种编目工作。研究采用多种多样性指数对植物物种多样性进行评估，并对所调查雪崩路径内的物种丰富度成因展开讨论。
