Terrestrial Plant Rule Has Passed!

The Terrestrial Plant Rule has been signed by the Governor and was published March 18th, 2019. The rule went into effect 30 days after publishing, so it became effective on April 18th, 2019. The rule states with respect to the 44 plant species included on the rule:

Indiana TPR is signed and published.

“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 (on April 18, 2019).

A pdf copy of the rule (plant list included) can be found here.
