Fassett's Locoweed (Oxytropis campestris var. chartacea)
Fassett's Locoweed (Oxytropis campestris var. chartacea), a State Endangered and Federally Threatened plant, is found in sandy, fluctuating lakeshores. Its appearance is sporadic depending on water level. Blooming occurs early May through late June; fruiting occurs late June through late July. The optimal identification period for this species is late May through late July.
Synonyms: Oxytropis chartacea
- Distinguishing characteristics: Herbage, bracts, and calyx not sticky; bracts densely hairy on the back; hairs slightly looser and more persistent; pods smaller, only 8 to 15 mm.
- Flower characteristics: Spikes dense, 2 to 4 cm, much longer in fruit; flowers purple, 1.5 to 2 cm.
- Fruit characteristics: Lance-ovoid, with a rather papery texture, not rigid, sparsely hairy with loose hairs, 1.5 to 2.5 cm including the beak.
- Leaf characteristics: Densely hairy at first with long, lax but not strongly spreading hairs, later more thinly hairy or partly smooth; leaflets 15 to 31, lance-linear to lance-ovate, 5 to 25 mm.
- Blooming phenology: early May through late June
- Fruiting phenology: late June through late July
- Optimum time to identify: late May through late July
- Growth form: Forb-erect
- Vegetative reproduction:
- Life cycle: Perennial
- Comments: Associated Species: Astragalus alpinus, Juncus alpinus, J. balticus, Panicum lindheimeri, Eupatorium perfoliatum, Lycopus americanus, Carex viridula, Potentilla anserina, P. norvegica, Sisyrinchium spp.

Habitats and landscapes
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.
General habitat information
- Habitat description: Found in sandy, fluctuating lakeshores. Its appearance is sporadic depending on water level.
- Soils: Sandy, rocky, and gravelly soils.
This table lists the natural communities that are associated with Fassett's Locoweed. 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).
This table lists the ecological landscape association scores for Fassett's Locoweed. The scores (3=High, 2=Moderate, 1=Low, 0=None) also correspond to the map.
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.
- Avoid known individual plant locations and conduct operations elsewhere when they are least likely to cause damage. Ideally, this would involve frozen, snow-covered ground. However, in areas of the state where frozen conditions are unreliable, very dry soils late in the growing season might be the best available alternative. Consult with a biologist, if needed.
- Avoid broadcast spraying of herbicides; use care with spot spraying.
Management guidelines are additional considerations that may help maintain or enhance habitat for this species
- Minimize disturbance to hydrology, including soil disturbance from rutting.
- Avoid disturbance to shorelines and the forest-beach interface.
- Survey for and control invasive plants prior to conducting timber operations, as these can be spread by vehicles and often respond vigorously to increased light; see forestry BMPs for invasive species.
