According to Wikipedia: An invasive species is a plant, fungus, or animal species that is not native to a specific location (an introduced species), and which has a tendency to spread to a degree believed to cause damage to the environment, human economy or human health.
What's The Big Deal?
Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources.
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.
Ornamental pear trees, most commonly known as Bradford pears, have been a popular landscaping tree in Indiana for decades.
So popular that they are crowding out native Indiana trees.
Cooperative Invasive Management
If you're looking to help address the problems of invasive species beyond your own property, consider joining or forming a local Cooperative Invasive Species Management Area (CISMA) or as they used to be called, a CWMA, Cooperative Weed Management Area. CISMAs are partnerships that can include federal, state, and local government agencies, tribes, individuals, and other interested groups that manage noxious weeds or invasive plants in a specific area (such as county). Marshall County SWCD, as a member of the Arrow Head Country RC&D, has an Invasive Species Resource Specialist, Erica Luchik, based in the Rensselaer Service Center.
CISMAs include local citizens, city, county, state, tribal and federal leaders, and both nonprofit organizations and for-profit corporations to more effectively control invasive plants across property lines. Some CISMAs have been started by government agencies taking a larger, region-wide approach to invasive plant management, while others have been formed by concerned citizens partnering with agencies, organizations, and corporations that can provide additional resources.
No matter where the impetus comes from to start a CISMA, the goal is the same: to work together with all interested parties in the area for more effective invasive plant management. Currently, there is no CISMA in Marshall County. If you would like to see a CISMA started, please contact the Marshall County SWCD office at 574-936-2024 x 3 or send an email.

What Can I Do?
You can help by reporting invasive plants when you find them! Indiana has partnered with EddMaps to allow Hoosiers to report invasives online or via their smartphone. You can also browse their website or app to view distribution maps, photos, and other information on area invasives.
Clean ~ Drain ~ Dry
“The best way for boaters to help protect our waters is by following the ‘Clean-Drain-Dry’ message,” said Eric Fischer, aquatic invasive species coordinator for the DNR Division of Fish & Wildlife.
Clean: When leaving the water, clean all equipment that touched the water. This includes watercraft hulls, trailers, shoes, waders, life vests, engines and other gear. Remove all visible plants, algae, animals and mud.
Drain: Drain accumulated water from watercraft or gear, including live wells and transom wells, before leaving the ramp or public access point.
Dry: Once home, let all gear dry for five days or more before using it in a different water body.
Dumping bait or unwanted aquarium or terrarium pets can introduce invasive species to waterways.
Dispose of all unused bait in a trash can instead of dumping it into the water or on the shore.
Monarch butterflies will lay eggs on black swallowwort, but the larvae will die.
