The following 14 threats were that were evaluated by natural resource professionals as medium to high severity throughout the State. They are a subset of the 50 threats to aquatic and terrestrial wildlife and systems outlined in the action plan. An explanation of how the threats detailed here were identified as statewide priorities is available in the Threats pages. Effects of each statewide priority threat on wildlife and landscape features are detailed, and conservation actions, research and monitoring to address these threats are identified.
Because many of these issues overlap, addressing them individually is difficult and some repetition is necessary. When possible, similar terrestrial and aquatic issues have been addressed jointly. Some identified priority threats have been broken into multiple issues to address them more effectively (e.g., Dredging and Channelization). These priority threats (and others not identified as statewide priorities) are also addressed by ecoregion and lake basin, and by landscape feature (within the Landscape Feature Summaries). There they are addressed at a finer scale, in the context of recommended conservation actions, research and monitoring for individual landscape features within specific ecoregions or lake basins.
Two threats ('Highest Priority Threats'), invasive species and fragmentation, have been brought to the front for emphasis, because they were repeatedly identified, through the ranking process and discussion at meetings and workshops, as being the highest priority threats to wildlife and landscape features in both aquatic and terrestrial systems throughout Michigan.
