Hairy-jointed Meadow-parsnip (Thaspium barbinode)
Hairy-jointed Meadow-parsnip (Thaspium barbinode), a State Endangered plant, is found in open woods and woodland edges, often with dolomite near the surface. Blooming occurs early May through late June; fruiting occurs early June through late October. The optimal identification period for this species is early June through late September.

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 open woods and woodland edges, often with dolomite near the surface.
- Soils: Moist soils with loam, sand or rock.
This table lists the natural communities that are associated with Hairy-jointed Meadow-parsnip. 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 Hairy-jointed Meadow-parsnip. 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.
Hairy-jointed Meadow-parsnip (Thaspium barbinode) has very few known occurrences in the state and is of the highest priority for conservation; we encourage you to consult with your District Ecologist or NHI Botanist for specific recommendations for your site.
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
- Maintain open to partially open canopy; avoid closed canopy conditions.
- Prescribed burns and/or brushing may be beneficial (dependent on local site conditions).
