After years in development, a rule that would ban the sale in Indiana of highly invasive plants (as identified by the Indiana Invasive Plant Advisory Committee and submitted to the Indiana Invasive Species Council) has been signed by the governor and will be in effect as of April 16, 2019.
During the arduous rule making process INASLA issued a statement of support for the rule and verbal testimony was given at a Department of Natural Resources public hearing by chapter Trustee David Gorden.
44 plant species are included in the rule which states:
“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 with the complete list of banned species can be found at: http://www.in.gov/legislative/iac/20181121-IR-312180316PRA.xml.pdf
Most of the species are not of commercial significance. However, several species are found and used in landscapes. They include:
Euonymus fortunei (Wintercreeper)
Phellodendron amurense (Amur Corktree)
Alnus glutinosa (Black Alder)
Berberis thunbergii (Japanese Barberry)
Coronilla varia (Crownvetch)
Celastrus orbiculatus (Asian Bittersweet)
The rule currently does not include Callery Pear and Norway Maple among the prohibited plants, despite the fact that both are identified as invasive. They were intentionally omitted because of the deemed economic value of the species to the Indiana nursery industry. It is hoped that after an appropriate transition period, they will be added to the list of prohibited plants.
