(Supplement) Regeneration of Pinus sylvestris, disturbance residuals and soil properties 5 years after a mixed-severity wildfire in the inner Italian Alps

We analyzed the abundance of Scots pine regeneration in a 257 ha wildfire in an inner-alpine forest. We sampled regeneration, percent soil cover by classes, physical and chemical properties of topsoils (A horizon, 0-5 cm) under four fire severity levels (unburned, moderate, moderate/high, high severity). 5 plots per severity level, circular (R= 3m). Analysis methods for soil properties as described in the paper.

本研究对阿尔卑斯内陆森林一处257公顷的野火迹地内的欧洲赤松（Scots pine）更新株丰度开展了分析。我们针对未过火、中度、中度/高度、高度共四级火烈度，采集了更新株数据、分级土壤覆盖百分比数据，以及各火烈度下表层土壤（A层，0~5 cm）的物理与化学性质数据。每个火烈度设置5个圆形样地（半径R=3 m）。土壤性质的分析方法详见对应论文。
