The purpose of this rule is to help prevent the introduction and
distribution of invasive aquatic plants into Indiana waters and wetlands.
The spread of invasive aquatic plants reduces boating, fishing and other
aquatic recreation opportunities. Such plants also negatively impact native
aquatic plants and reduce property values around lakes and ponds.
A list of the prohibited plants and the exact language of the rule is
available at http://www.in.gov/legislative/iac/20120411-IR-312120050PRA.xml.pdf.
Many of these invasive plants have been used in aquariums or water gardens
for years. Some are already widely established. The most popular of such
plants currently sold include flowering rush, Brazilian elodea (Anacharis),
yellow flag iris, parrot feather and yellow floating heart.
Cost for management or eradication of invasive species already in Indiana
waters easily exceeds $1 million annually when Department of Natural
Resources and lake association costs are combined.
Aquarium and water garden hobbyists can help slow the spread of such species
by purchasing non-invasive or native plants.
Boaters can help stop their spread by removing plants, mud and other debris
from their watercraft when they remove them from the water.
The new rule will be administered by the DNR Division of Entomology & Plant
Pathology, in cooperation with the Division of Fish & Wildlife.
