Illinois had 249 aquatic and terrestrial wildlife species classified as wildlife species of greatest conservation need (GCN). Of these 249 GCN species, 29 are mussels, 80 are fishes, 14 are amphibians, 23 are reptiles, 83 are birds and 20 are mammals. Problems or threats to the GCN species populations in Illinois are commercial and industrial development, landfill construction or operation, dams, road construction, urban development, water diversion, municipal and industrial point source, commercial harvest, conversion of riparian forests, excessive non-commercial harvest or collection, channel maintenance and confined animal operations. Other problems or threats to GCN species are crop production practices, excessive groundwater withdrawal, fire suppression, management of or for certain species, channel alteration, exotic species, parasites, pathogens, recreation, grazing, predation, forestry activities and resource extraction. The Illinois Comprehensive Wildlife Conservation Strategy has addressed these problems or threats to the GCN species population with conservation actions. These actions include decreasing the data gap by gathering more information on GCN species, by fire management with controlled burned, with habitat protection by initiating projects to protect existing habitat or habitat components, with habitat restoration and improvement by initiating projects to restore or enhance existing habitats, with land acquisition by purchasing land or conservation easement that is important to GCN species, with population management by directly manipulating GCN species population by restocking, translocation an harvest management, with public
relations and education
by increasing public awareness of GCN species and key habitats through education and public outreach, with threat abatement by mitigating existing threats including pollution, predation an competing species and with other conservation action plans that have not been covered previously.
