Distribution of ash trees within areas less than half a hectare in Great Britain

The dataset consists of a distribution map of ash trees (Fraxinus excelsior) within woodland areas of less than half a hectare across Great Britain. The data is derived from Countryside Survey 2007. Trees were mapped in 569 1km sample squares across Britain, and this national estimate dataset was derived from the sample data using ITE Land Classes.

该数据集收录了英国境内面积不足半公顷的林地中白蜡树（Fraxinus excelsior）的分布图。数据源自2007年的乡村调查。在英国的569个1平方公里的样本方格内进行了树木测绘，并利用 ITE 土地分类法从样本数据中推导出全国估算数据集。关于该数据集的详细信息可查阅https://doi.org/10.5285/7f7c99c7-5457-444d-978a-fe7b01a85fd0。
