The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.
This table lists the natural communities that are associated with Slender Bulrush. Scores for natural community associations are: "significant" association (score=3), "moderate association" (score=2) or the species can be present but is only weakly associated with the community (score=1).
| Natural communities | score |
|---|---|
| Emergent Marsh | 3 |
This table lists the ecological landscape association scores for Slender Bulrush. The scores (3=High, 2=Moderate, 1=Low, 0=None) also correspond to the map.
| Ecological landscape | score |
|---|---|
| Central Sand Hills | 2 |
| Forest Transition | 2 |
| Northwest Sands | 2 |
| Southeast Glacial Plains | 2 |
| Western Coulee and Ridges | 2 |
The Endangered Resources Program has developed avoidance measures and management guidelines for plants on the Natural Heritage Working List. These are a work in progress, and we welcome your suggestions and feedback. Sources used in developing this information can be found here.
These are specific actions designed to avoid "take" (mortality) of this species.
Management guidelines are additional considerations that may help maintain or enhance habitat for this species
