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.
