Nature Preserves > Invasive Plant Species Invasive Plant Species

Of the more than 2,000 species of vascular plants in Indiana, roughly 25 percent are non-native to Indiana. Most don't create problems in natural areas, but many do, competing with and crowding out more desirable native species.

Highlights of Non-Native/Invasive Indiana Plants

The Midwest Invasive Species Information Network (MISIN) is a regional effort to develop and provide an early detection and rapid response (EDRR) resource for invasive species.

The goal of this regional resource is to assist both experts and citizen scientists in the detection and identification of invasive species in support of the successful management of invasive species.

Examples of non-native plants include:

Bush Honeysuckle

The Indiana Invasives Species Council is another source of information on invasive species in Indiana.

Use EDDMaps to report invasive plants in Indiana.

Organizations Focused on Controlling Invasive/Non-Native Species

Those organizations that focus a great deal of time, money and effort controlling undesirable non-native and invasive species in natural areas include:

Although many of these detrimental plants are sold in nurseries and planted by people who are generally unaware of the problems they create, there are plenty of native plants that could be used instead for landscaping. 

Alternatives to Non-Native/Invasive Plant Species

To learn more about alternative native species that can be used in landscaping, as well as, non-native and invasive species, check out the Indiana Native Plant and Wildflower Society website.
