EWINA_RICH : a database of EarthWorm native and alien species richness accross North America

<p><strong>EWINA_RICH</strong> gathers data on observed and predicted native and alien species richness of earthworms species across geographical units of North America (Mexico, US and Canada), based on data from 1850 to 2021.</p><p>Please refer to the published paper for the details about the process to produce the predictions and the general interpretation of the results.</p><p>Data are given at two distinct spatial resolutions</p><blockquote><p><strong>- Data at the resolution of counties or equivalent</strong></p><ul><li><a href="https://zenodo.org/api/files/61402820-f567-48fb-b030-2353b156a676/EWINA_counties.geojson">EWINA_counties.geojson: </a>Spatial layer of all counties or alike geographical units, with environmental covariates.
