minus-squaresleet01linkfedilink1•1 year agoI found out just a few years ago that many earthworms are invasive species in North America: https://en.m.wikipedia.org/wiki/Invasive_earthworms_of_North_America. Apparently the last ice age cleared out all the earthworms north of the 49th, and existing native species didn’t migrate back after the glaciers receded, leaving many northern and west-coast forests without earthworms at all.
