Update on Terrestrial Plant Rule - Signed by Governor and published March 18, 2019.

The Terrestrial Plant Rule has been signed by the Governor and was published March 18, 2019.

The rule goes into effect 30 days after publishing, so it should be effective around April 16, 2019.

The rule states with respect to the 44 species included on the rule:

“a person must not:

(1) Sell, offer or grow for sale, gift, barter, exchange, or distribute a species;

(2) Transport or transfer a species; or

(3) Introduce a species.

(4) Subdivisions (1) and (2) of this subsection are effective one year after the effective date of this rule.”

Note that section (3) “Introduce a species” is effective immediately (around April 16, 2019).

A copy of the rule (plant list included) is attached.

The Governor also declared April 7-13, 2019 as Invasive Species Awareness Week in Indiana (proclamation is attached). Whoop Whoop! It’s a great week to talk about our amazing native plants and to remove invasives ones.   

And it just so happens that many Indiana residents have decided this spring (Mar-May) to participate alongside our fellow states in an appreciation of our wonderful natural areas and green spaces by participating in Weed Wrangles®. Please see the list of events and an explanation of a Weed Wrangle® in the attached document, title, “Weed Wrangle Indiana...”

We know there are many invasive species events occurring across the state this spring to make our state a wonderful place to live. All efforts are much appreciated!

One last update. The Indiana Invasives Initiative is making headway. In roughly 13 months we have increased our Cooperative Invasive Species Management Areas (CISMAs) by 10. There are now 17 functioning CISMAs in Indiana and many of them are hosting Weed Wrangles® and working hard to share the great news about our natural areas and how each one of us can make a positive impact. This collection action shows we understand the impacts of our actions, we are willing to learn together to intensify positive impacts, and that we understand the need to collaborate.

Have a great week and I hope to see you at a couple of Weed Wrangles® or other events that celebrate our special native plants and wildlife this spring. 



So just what is a Weed Wrangle Indiana®?
Weed Wrangles are events hosted nationwide to gather volunteer effort to help control invasive plants that are negatively impacting our public parks, green spaces and natural areas. For instance, garlic mustard (Alliaria petiolata) is a plant in the mustard family that is native to Europe that can harm our native plants and wildlife. In addition to eliminating our native plants, research shows that garlic mustard can be fatal to several butterfly species. For instance, the West Virginia white butterfly (Pieris virginiensis) is a rare species that lays eggs on plants in the mustard family. Butterfly eggs laid on garlic mustard do not survive. Community members learn to identify and control through hands-on removal of these invasive trees, shrubs, vines and plants.
Supervised by an expert, volunteers are learning across America to identify and manage invasive plants. We are hoping that by engaging our community members and challenging them to act in their own spaces we foster a collective effort to have a large and positive impact for our native plants and wildlife.
Please join us by attending a Weed Wrangle Indiana® in your area, and consider hosting one next year. You may contact Dawn Slack at dawn.slack@tnc.org for more information on how to host a Weed Wrangle Indiana®. You will not only learn about plants and wildlife, learn how to manage invasive plants, but will also join a national effort to positively impact our communities.
And it’s fun! Just ask someone who has participated in a Weed Wrangle®. It’s a rewarding couple of hours spent with community members to show our appreciation for our green spaces and natural areas.
