Threat ImpactVery high - high

Range Extent<100-250 square km (less than about 40-100 square miles)

Number of Occurrences6 - 20

Rank Reasons

Endemic to central and northwestern Wisconsin and restricted to the shorelines of inland lakes. Only 7 occurrences are known extant. The species' habitat is susceptible to a wide range of detrimental activities. The greatest immediate threat is probably changes to the lake hydrology. invasive species (spotted knapweed (Centaurea biebersteinii) and sweet clover (Melilotus ssp.)), and to a lesser extent, all-terrain vehicle use of the shorelines.

Range Extent Comments

Restricted to small inland lakes at eight sites in central and northwestern Wisconsin: Waushara, Portage, and Bayfield counties. Historic populations in Bayfield and Waushara counties.

Occurrences Comments

Eight extant populations, 10 total occurrences (1 Historic and 1 Extirpated).

Threat Impact Comments

The present or threatened destruction, modification or curtailment of present habitat or range, use of motorized vehicles on shorelines, pesticide drift and fertilizer run-off, road run-off, excessive trampling, water-level drawdown, and destruction of habitat through grazing. Other potential threats include dredging of shoreline habitat by landowners or counties, digging of plants, competition from sweetclover and spotted knapweed, and the alleged allelopathic properties of an associate, orange hawkweed (Hieracium aurantiacum). Landowners have become good stewards of the species, protecting and monitoring plants (USFWS 2015).

Ecology & Habitat

Habitat

Open to partially shaded, sandy or gravelly shorelines of small landlocked seepage lakes. Apparently intolerant of competition and shading; not found in abundance where dense grasses, woody shrubs, or trees have become established. Dependent on lake level fluctuations to maintain an open habitat.
