Coverage of dominant plant taxa, water surface area and hydrogeomorphological information for kettle holes surveyed in 2016, 2018 and 2020.

The published Excel tables contain coverage data from dominant plant communities (response variables) as well as from environmental variables (explanatory variables) collected at kettle holes.
The dominant plant communities and their coverage were determined on the basis of UAS images in summer 2016, 2018 and 2020. The delimitation of homogeneous vegetation from the surrounding vegetation areas, the water or the soil was done manually using the color, texture and/or shape in the UAS images. In the end there were 14 dominant plant communities.
The environmental variables include the kettle hole and the water surface area, which were determined every year based on the same UAS images as dominant plant communities. In addition, we publish the hydrogeomorphological types of the examined kettle holes and the class of the shore slope, both variables included as dummy variables.

已发布的Excel表格包含采集自壶穴（kettle hole）的优势植物群落盖度数据（响应变量）与环境变量数据（解释变量）。
优势植物群落及其盖度通过2016、2018及2020年夏季的UAS影像确定。研究人员依托UAS影像中的色彩、纹理和/或形状，人工完成同质植被与周边植被区域、水体或土壤的边界划定工作，最终共划定14个优势植物群落。
环境变量涵盖壶穴与水体表面积，二者均基于与优势植物群落相同的UAS影像逐年测算。此外，本数据集还包含本次研究涉及壶穴的水文地貌类型与岸坡坡度等级两类变量，两类变量均以虚拟变量形式录入。
