State status
Status and Natural Heritage Inventory documented occurrences in Wisconsin
The table below provides information about the protected status - both state and federal - and the rank (S and G Ranks) for A Predaceous Diving Beetle (Hygrotus marklini). See the Working List Key for more information about abbreviations. Counties shaded blue have documented occurrences for this species in the Wisconsin Natural Heritage Inventory database. The map is provided as a general reference of where occurrences of this species meet NHI data standards and is not meant as a comprehensive map of all observations.
Note: Species recently added to the NHI Working List may temporarily have blank occurrence maps.

Wildlife Action Plan
Natural community (habitat) associations
The table below lists the natural communities that are associated with A Predaceous Diving Beetle. Only natural communities for which A Predaceous Diving Beetle is "high" (score=3) or "moderate" (score=2) associated are shown. See the key to association scores for complete definitions. Please see the Wildlife Action Plan to learn how this information was developed.
| Natural community | Score |
|---|---|
| Emergent Marsh | 2 |
Ecological landscape associations
The table below lists the ecological landscape association scores for A Predaceous Diving Beetle. The scores correspond to the map (3=High, 2=Moderate, 1=Low, 0=None). For more information, please see the Wildlife Action Plan.
| Ecological landscape | score |
|---|---|
| Forest Transition | 3 |
| North Central Forest | 3 |
| Southeast Glacial Plains | 3 |
| Western Coulee and Ridges | 3 |
Landscape-Community combinations of highest ecological priority*
Ecological priorities are the combinations of natural communities and ecological landscapes that provide Wisconsin's best opportunities to conserve important habitats for a given Species of Greatest Conservation Need. The 10 highest scoring combinations are considered ecological priorities and are listed below. More than 10 combinations are listed if multiple combinations tied for 10th place. For more information, please see the Wildlife Action Plan.
| Ecological Landscape | Community |
|---|---|
| North Central Forest | Emergent Marsh |
| Southeast Glacial Plains | Emergent Marsh |
| Western Coulee and Ridges | Emergent Marsh |
| Forest Transition | Emergent Marsh |
* Ecological priority score is a relative measure that is not meant for comparison between species. This score does not consider socio-economical factors that may dictate protection and/or management priorities differently than those determined solely by ecological analysis. Further, a low ecological priority score does not imply that management or preservation should not occur on a site if there are important reasons for doing so locally.
Issues/threats and conservation actions
Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.
