| First, because earthworms are non-native exotics, and it is illegal to release exotic species into the wild in Minnesota. | |
| Second, because they are destructive of our woodlands and forests. They eat up the 'duff' of leaves and litter that provides nutrients to seedlings and undergrowth, and cause the death of tree seedlings, wildflowers, and ferns, and increased surface runoff and erosion. |
A website of Mn/DNR has more information about earthworms, how they got here (No earthworms are native to the area; they came with European settlement!) and the harm they are causing in northern forests. Check it out: http://www.dnr.state.mn.us/hot_topics/invasive_earthworms.html and then share the information with your fishing buddies.
