A. 15. SUMMARY OF AQUATIC INVASIVE SPECIES MANAGEMENT IN INDIANA 
A.15.1. AQUATIC INVASIVE SPECIES MANAGEMENT PLAN 
Indiana’s Aquatic Nuisance Species Management Plan was published in 2004 (see 
Appendix B, State Aquatic Invasive Species Management Plan Summaries for a general 
description of the Plan). 
A. 15.2. AQUATIC INVASIVE SPECIES PROGRAMS AND ACTIVITIES 
• Early Detection and Rapid Response, Indiana Department of Natural Resources, 
(INDNR), Division of Fish and Wildlife. The Division is conducting treatment of 
Brazilian elodea in Griffy Lake, as well as a survey and development of an aquatic 
vegetation management plan. Whole-lake herbicide treatment began in 2006 and will 
continue in 2007. Access restrictions were implemented in the spring of 2006 to prevent 
the movement of Brazilian elodea to other waters. The Division is also conducting rapid 
response for hydrilla, first discovered in 2006 at Lake Manitou. Response included an 
herbicide treatment and access restrictions in the fall of 2006. Large-scale aquatic 
herbicide treatments are planned for the spring of 2007. 
• Lake and River Enhancement Program, INDNR Division of Fish and Wildlife. The 
Program provides grants to lake associations for the control of aquatic invasive plants. 
• Yellow Perch Research, INDNR Division of Fish and Wildlife, Ball State University. 
Researchers examine the impacts of aquatic invasive species (AIS) such as zebra mussels 
and round goby on yellow perch and other native species in Lake Michigan. 
• Management of sport fisheries, INDNR Division of Fish and Wildlife. The Division 
is responding to AIS’ threats to sport fisheries through the following actions: (1) 
eradicating fishery altogether; (2) stocking predators; and (3) manipulating habitat (e.g., 
lake drawdowns to reduce aquatic invasive fish and plants). 
• Emergent aquatic plant control, INDNR Division of Nature Preserves. The Division 
is controlling purple loosestrife, Phragmites, and reed canary grass on Indiana’s nature 
preserves. A purple loosestrife biocontrol program has been implemented using beetles 
on Nature Preserve properties as well as other areas that contain large areas of purple 
loosestrife. Phragmites and reed canary grass have been sprayed with glyphosate-based 
herbicides, though the Division uses some plant-specific herbicides for reed canary grass. 
The Division has also performed some herbicide control for the narrowleaf cattail and 
hybrid cattail, though there is some debate about whether narrowleaf cattail is native to 
North America.
