Datasets for many plants naturalized as aliens abroad have also become more common within their native regions

In our research we used data on the grid cells occupancy of native species from 10 different European regions, for at least two time period, spanning over decades to centuries. Here we have provided all the necessary data that will need to reproduce our research (specifically as Source data file). (see methods and supplementary methods for details). In addition, we also provide the field description and R code.
