Here is an interactive map showing the suitability of Europe for the Japanese beetle (Popillia japonica). 

This map is the result of our INRAE team's modelling efforts and shows predictions of environmental suitability. You can read more about this work in our previous blog post and in our recent publication (Borner et al., 2023).

In addition to the suitability map, our dataset also includes files used in our modelling approach, such as:

• a raster file of the distribution of Popillia japonica occurrences, collected using citizen science platforms and standardised surveys,
• a raster file of the distribution of Coleoptera species collected through citizen science and used as pseudo-absences in the models,
• a raster stack of predictors used in modelling (climate, human-related variables, land use, soil properties, etc.).

The extent of the raster files is global, the spatial resolution of the raster files is 4 km x 4 km.
