Findings and Recommendations from the Indiana Invasive Species Task Force
July 7, 2008

From the EXECUTIVE SUMMARY:

"Indiana is the crossroads of America—our waterways, railroads, highways and other transportation facilities are some of the finest in the nation. That distinction as a hub of transportation and commerce means Indiana has more than its share of invasive species problems. Invasive species enter Indiana through both transportation and commerce, and the rate at which invasive species are entering Indiana is increasing rapidly. We are also at a crossroads in time; by taking action now, we can lessen the impact of invasive species to our economy and environment.

Invasive species harm our economy, environment, and human health in many ways. Just one invasive insect, the Asian soybean aphid, has significantly decreased soybean productivity in the US. In 2003 an estimated 300 million bushels were lost to this pest. With today’s soybean prices hovering at $15/bushel this translates into a loss valued at $4.5 billion nationally. There are dozens of invasive plants, aquatic species, insects, plant diseases, terrestrial animals, and animal diseases that threaten Indiana. Asian bush honeysuckle has invaded forests in every county in the state, significantly decreasing tree regeneration and growth. Hydrilla has invaded Lake Manitou in Fulton County, and if appropriate action is not taken it could spread to other waters and result in reduced aquatic biodiversity, recreational opportunities, and fish populations. Emerald Ash Borer is killing ash trees in northern and central Indiana, and will most likely be moved by people south to the vast forests of southern Indiana. Feral hogs are destroying crops and forested land in southern Indiana, potentially carrying brucellosis and pseudorabies, two diseases that have been eradicated in our domestic livestock but could be reintroduced by these animals."
