NW Washington | Yes, it is some of the illegal alien worms that are the problem, not the native species. It is a big problem in northern forest, like Minnesota. One more invasive species issue. I had "night crawlers" where I used to live and they can devour and amazing amount of organic residue in short order. As the name implies they come out on to the soil surface at night or when you get a lot of rain. I copied this paragraph from the above link.
"Not all foreign earthworms are destructive, however. Of the thousands of species around the globe, only approximately 15 of the European and Asian varieties are considered to be bad guys. Hale says that despite distinct differences in these worms’ anatomy, color and behavior, most people never really notice and think “a worm is a worm.” But research is showing that different species can have very different environmental impacts." | |
