Worm Lesson

with 2 comments

Yesterday I learned something that surprised me, especially for the extent of time —basically, my lifetime— about which I have been clueless. I assumed earthworms were native to my region and entirely beneficial. They provide food for our birds and other critters, and they aerate and enrich the soil.

Invasive EarthwormsAu contraire! I spotted an article in the sports section of a local newspaper aiming to educate people who fish about not dumping their leftover angle worms on the ground. Worms should be disposed of in the trash.

Why? First of all, the terrestrial earthworms are a non-native invasive species from Europe and Asia! I had no idea. Second, they are harming our hardwood forests. They actually disrupt the natural decomposition of leaf litter on the forest floor and turn good soil into grainy, dry worm castings (poop), which then can’t support the understory plants of our forests.

Apparently, they are welcome to help in my compost pile, but they are not friendly to our woods. Up at our lake place in Hayward, WI, our favorite flowering woodland plant on the forest floor is the trillium. Around Memorial day at the end of May, when we head up for “work-weekend” to open up the property for the summer, we often find a carpet of white blossoms covering the ground.

According to the literature I have reviewed, trillium is one of the plants that is lost to the earthworms.

All of my life I have assumed that earthworms were a good thing. I’m afraid I will no longer think of them the same way at all. I would much rather have a thick, healthy layer on our forest floor that could support a robust undergrowth, than a dry, leafless surface of worm poo.

Anglers, contain those crawlers!
