Ecoregions have been noted to be determined by vegetation as well as soil associated with the region. It would be interesting to look at how soil composition may shape the ecoregion's composition. Possible open source data can be acquired using SoilGrids : https://www.isric.org/explore/soilgrids .
It would also be interesting to compare the soil composition of the whole ecoregion cut into regular intervals vs. where angiosperm occurrences have been georeferenced in our dataset.
