Biodiversity on avalanche tracks, a case study in the national park "Gesäuse" (Styria, Austria)

摘要: On the investigated avalanche tracks soils are very shallow, stony, nutrient-poor, base-rich rendzinas that developed over limestone debris. The sites steep and mainly east-facing slopes located in montane beit. Under these conditions, plant stands characterized by a high species density. average number of vascular within plot size 20 m2 is 71, bryophyte 5. species-rich stands, colourful when bloom, dominated herbs, resulting aesthetic value an increased diversity butterflies. have nature-conservation because natural ecological processes still happens, leading to near-natural, ecosystems.
