Results from Lower Ohio River Survey for Aquatic, Wetland, and Riparian Invasive Species now available online

The Central Hardwoods Invasive Plant Network (or Chip-N) has recently completed a collaborative survey of invasive species along the lower Ohio River Valley and the results are now available online at:

Chip-N is an informal partnership between Cooperative Weed Management Areas in the southern portions of Illinois, Indiana, and Ohio (River to River CWMA, Southern Indiana CWMA, Iron Furnace CWMA and the Southeast Ohio NNIS Interest Group).

This project, with funding from USFS State & Private Forestry, USFS Eastern Region and several other sources, worked with The Nature Conservancy, Notre Dame University and the University of Georgia Center for Invasive Species and Ecosystem Health to design and implement the surveys and make the results available online.

This project resulted in the discovery of many new infestations of invasive species along the Lower Ohio River, its tributaries, and some nearby reservoirs. Most notably was the discovery of widespread infestations of Hydrilla along the Ohio River adjacent to Indiana and Ohio.
