If you're going to be soaking up the sun during this warm October weekend, you might as well look for jumping worms while you're at it!
Extension's terrestrial invasive species team needs your help mapping jumping worms across Minnesota. These invasive earthworms can dramatically change soil conditions and disrupt forest ecosystems.
Even though parts of northern Minnesota have already seen frost, adult jumping worms can remain active until a hard freeze. That means there’s still time in much of Minnesota to find and report active jumping worms before the season winds down.
Found a jumping worm? Report it at EDDMapS.org or email [email protected] with clear photos of the clitellum.
