Post-fire vegetation succession after 5 years in managed pine forests at different time since clearcutting

To study plant community succession after fire and how it is influenced by time since previous (pre-fire) disturbance, vegetation data were collected in 2019, 5 years after a large (13000 hectare) wildfire in boreal Southern Sweden (county Västmanland). Plant communities were surveyed in severely burnt even-aged pine stands that varied in time since clearcutting (0-123 years) before the wildfire occurred. Data includes at the plot-level (50x50cm quadrats): vascular and moss species frequency, total cover, dead wood, and canopy openness. At the stand-level: means for all species, community weighted trait means (trait data from databases), and distance to the fire perimeter.

Two files are archived. (1) post_fire_vegetation_TSC_plotlevel_data.csv contains all raw data from each surveyed vegetation plot, (2) post_fire_vegetation_TSC_standlevel_trait_sp_data.csv contains averaged species abundance data and community weighted trait means at the stand level.

为研究火灾后的植物群落演替规律及其受火前干扰时长的影响机制，研究团队于野火发生5年后的2019年开展植被数据采集工作，该野火为发生于瑞典南部北方针叶林（boreal）区域的1.3万公顷大型野火，地处西曼兰郡（Västmanland）。研究针对野火发生前皆伐时长介于0至123年的严重火烧同龄松林样地，开展植物群落调查。数据集包含样方（50cm×50cm）与林分两个层面的观测数据：样方层面涵盖维管植物（vascular plant）与苔藓物种频度、总盖度、枯木（dead wood）量及冠层开度（canopy openness）；林分层面涵盖所有物种的均值、群落加权性状均值（community weighted trait means，性状数据来源于公共数据库），以及样地至火边界的距离。

本次研究共归档两份数据文件：(1) post_fire_vegetation_TSC_plotlevel_data.csv 包含所有调查植被样方的原始数据；(2) post_fire_vegetation_TSC_standlevel_trait_sp_data.csv 包含林分水平下的物种丰度均值数据与群落加权性状均值。
