Unpublished data on leaf rust infection and herbivory in willow plantations

The data were collected during 2015 and 2018 within ~20 willow plantations in the Uppsala area, Sweden. I neither found the time nor research funding to use the data in a scientific publication or otherwise. The data from 2015 also offer canopy openness and vegetation cover within the willow short rotation plantations. The data from 2018 also included the establishment of plots for measuring stem diameter that were intended to be measures again. An associated data set (10.5281/zenodo.6995718) consist of similar estimation on willow bushes in Europe.本数据集采集于2015至2018年，采集地点为瑞典乌普萨拉（Uppsala）区域内约20片柳树人工林。笔者暂未获得足够时间与研究经费，无法将该数据用于学术发表或其他相关研究。2015年采集的数据还包含柳树短轮伐人工林的林冠开度与植被覆盖度信息。2018年采集的数据增设了用于测量茎干直径的样地，计划后续开展复测工作。另有关联数据集（10.5281/zenodo.6995718）针对欧洲地区的柳树灌丛开展了同类评估。
