Missouri Rock-cress (Boechera missouriensis), a Wisconsin Special Concern plant, is found in soil pockets on acidic cliffs, as well as in pine forests on sterile sand and gravel outwash plains. Blooming occurs late May through late June; fruiting occurs late June through late July. The optimal identification period for this species is late May through late June.
Synonyms: Arabis laevigata var. missouriensis, Arabis missouriensis, Arabis missouriensis var. deamii, Arabis viridis, Arabis viridis var. deamii

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 Missouri Rock-cress. 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 |
|---|---|
| Northern Dry Forest--young seral | 2 |
| Northern Dry Forest--mid seral | 2 |
| Northern Dry Forest--late seral | 2 |
| Aspen-Birch | 1 |
| Dry Cliff | 3 |
| Bedrock Glade | 3 |
| Dry Prairie | 2 |
| Oak Barrens | 3 |
| Pine Barrens | 2 |
This table lists the ecological landscape association scores for Missouri Rock-cress. The scores (3=High, 2=Moderate, 1=Low, 0=None) also correspond to the map.
| Ecological landscape | score |
|---|---|
| Forest Transition | 2 |
| North Central Forest | 2 |
| Northeast Sands | 3 |
| Northern Highland | 1 |
| Northwest Sands | 1 |
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
