• Upper Illinois River habitat mapping, IDNR, INHS. INHS is conducting field 
monitoring to evaluate Asian carp habitat. 
• Technical assistance for market development, IDNR, Fisheries, Illinois Department 
of Commerce and Economic Opportunity (DCEO). The harvest program provides 
technical assistance for required analytical data to establish markets for Asian carp. 
Illinois’s DCEO has provided implementation costs for start-up and phase 1 of an 
intensified harvesting program. 
• Contaminant analysis for market development, IDNR, INHS, University of Illinois. 
The program provides additional contaminant analysis for market development. 
• Goby round-up/Carp Corral, a joint program with IDNR, U.S. Army Corps of 
Engineers, U.S. Fish and Wildlife Service, the Metropolitan Water Reclamation 
District. The program monitors the spread and expansion of round goby and 
bighead/silver carp populations in the Illinois River System toward Lake Michigan. 
• Eradication, IDNR. IDNR conducts eradication of Eurasian watermilfoil using 
Chemical- 2-4D and sonar. The agency is also experimenting with treatment timing and 
dosage for better long-term effects. A new project will target curly leaf pondweed. 
• Permanent Electric Dispersal Barrier, IDNR. An electric barrier has been 
implemented in the Chicago Sanitary and Ship Canal to deter the inter-basin transfer of 
invasive fish between the Great Lakes and Mississippi River. The barrier will be 
operated and funded by the IDNR upon completion; in the interim, the U.S. Army Corps 
of Engineers maintains management of the barrier. 
A.14.3. CLIMATE CHANGE CONCERNS 
• Climate change may have an indirect impact by allowing some species to expand into 
new ranges where they have not historically been found. If certain regions warm up (or 
cool down), they may be colonized by species that were only marginally adapted to the 
warmer (or cooler) temperatures. 
• Illinois’s ANS Plan includes vectors that are exacerbated by climate change: 
As use of the Great Lakes intensified as a transport route for 
commerce, the rate of introduction of aquatic nuisance species also 
increased. More than one-third of the organisms have been 
introduced in the last 30 years, a surge coinciding with the opening 
of the St. Lawrence Seaway. Other human activities contributing 
to the transport and dispersal of aquatic nuisance species in the 
Great Lakes and inland state waters include the release of 
organisms from the ballast water of ships, transport and release 
from the bottoms of ships, movement or intentional release of 
aquaculture and sport fishery species along with their associated 
A-44
