What are invasive species?
As long as humans have traveled across the earth, they have purposefully and sometimes unknowingly transported plants, animals, insects, and other organisms on their bodies, in shipping containers, on their shoes, etc. When an organism is brought to an area it did not traditionally grow, it is considered non-native. When a non-native species causes harm to the environment, human health, and the economy, it is considered an invasive species.
Why are they a problem?
Some of these exotic species, when uninhibited by the environmental conditions and predators of their natural home, are able to feed, reproduce, and spread with no limitations. These species "invade" and spread, sometimes causing great environmental destruction in their path. The proliferation of invasive species in an ecosystem disrupts the complex and critical relationships that our native species have with their physical environment and other organisms.
How do I know if I have invasive species on my property?
Resources are available on this page and elsewhere online that can help you identify invasive species and suggest removal options. Alternatively, feel free to contact our office for a consultation.
What can I do if I have invasive species on my property?
Removal methods for invasive species vary widely depending on their reproduction and ecology and unfortunately, it takes maintenance to keep invasive species from recolonizing an area. Establishing native species after removal can help keep invasives at bay. Refer to the resources on the right for more info.
If you'd rather hire out services for invasive removal, refer to this Grow Indiana Natives list of invasive plant removal contractors.

Learn about the new Indiana Terrestrial Plant Rule
Terrestrial Plant Rule Info:
Beginning April 18, 2020, the Indiana Terrestrial Plant Rule (312 IAC 18-3-25) will make it illegal to sell, gift, barter, exchange, distribute, transport or introduce in Indiana any of 44 invasive pest plant species without a permit. While it will be illegal to transport or gift these 44 plants among private property owners, it will not be illegal to have these species on your property. That being said, we do encourage you to work to remove these species from your property.
See the list of 44 regulated species on the IDNR website.
Individual invasive plant assessments can be reviewed on the Indiana Invasive Species Council website).

Invasive Spotlight: Wintercreeper
Wintercreeper is an aggressive perennial woody vine/groundcover that spreads prolifically in sun, shade, and many soil conditions. Winter creeper is native to Asia and was introduced to the US via the landscape trade. It damages natural and suburban areas by out competing and eliminating native ephemerals and other flowers. The vine can kill mature trees and shrubs. Wintercreeper is an evergreen so it is easily identified even in winter. Controlling wintercreeper is no easy task. Hand cut vines at the base and apply a Glyphosate herbicide to the cut stump in late winter. Hand control via pulling for small infestations can be effective but left roots will re-sprout. Persistence is key. Herbicide applications in late fall are options.
