Report Terrestrial invasive species

DNR is seeking sighting information for invasive species in Indiana. If you believe you have spotted an invasive species, report it and, if possible, get pictures to assist in expert identification.

Terrestrial Plant Rule

The Terrestrial Plant Rule (312 IAC 18-3-25) designates 44 species of plants as invasive pests. This rule makes it illegal to sell, gift, barter, exchange, distribute, transport, or introduce these plants in the State of Indiana. Learn what you need to know in the Terrestrial Plant Rule Brochure.

This rule went into effect April 18, 2019 .

Plant species already in trade will be prohibited from sale one year later (April 18, 2020).
