This final report includes documentation of the approaches, methods, and results of our efforts to evaluate current and potential Species in Greatest Need of Conservation (IWAP Appendix I). We reviewed 563 taxa and provide draft updates and revisions of the Status, Conservation Objectives, and Stresses for non-mollusk invertebrate taxa in Illinois. We propose listing 166 of these as Species in Greatest Need of Conservation including 129 species from the 2005 list of 375 taxa and 36 of the 188 species newly evaluated in this project. Additionally, we propose a Watch-List of 245 invertebrate species which appear to be rare or declining but that have insufficient information to conduct a thorough conservation assessment at this time.Illinois Department of Natural Resources State Wildlife Grant Program Project Number T-88-R-001unpublishednot peer reviewedOpe
