Counties with Mapped NHI Occurrences

Prairie Dunewort (Botrychium campestre), a Wisconsin Endangered plant, is found on Lake Michigan dunes and dry prairies. The optimal identification period for this species is throughout June.

 
 
 

Prairie dunewort is a fern, 3-18cm tall, with one smooth, oblong, pinnate frond 4cm x 1cm, erect and very fleshy, usually with 5 pairs of lobes. Its stem is bright green and smooth. Its sporeophore (spore producing organ) emerges from base of a leaf and is ~1.5 times the size of the leaf.

Its fronds appear in late-spring and die in late-spring to early-summer, much sooner than similar moonworts.

Rhizomatous. Fruiting occurs April through June.

Perennial. The optimal identification period for this species is throughout June.

Associated species include Ammophila breviligulata, other Botrychium species, Asclepias syriaca, Orobanche fasciculata, Juncus balticus, Lathyrus japonicus, and Artemisia campestris.

Prairie dunewort is found on Lake Michigan dunes and dry prairies with sandy or gravelly soils.

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 and use care with spot spraying.

Avoid locating landings, staging areas, or access routes in open sandy areas dominated by native grasses.

Prescribed burns and/or brushing may be beneficial, dependent on local site conditions and burn frequency. Rotational burns with annual unburned refugia may be preferred.

Maintain and restore open habitat through selective clearing and brushing.

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.

Species of Greatest Conservation Need (SGCN) are associated with habitats (or natural communities) and places on the landscape. Understanding relationships among SGCN, natural communities and ecological landscapes help us make decisions about issues affecting SGCN and their habitat and how to respond.

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the Wisconsin Wildlife Action Plan because lack of information can threaten our ability to successfully preserve and care for natural resources.
