PROTECTING WISCONSIN'S BIODIVERSITY

Blooming occurs in July, fruiting August through early-September.

Annual. The optimal identification period for this species is July through August.

Associated species include Nymphaea odorata, Brassenia schreberi, Dulichium arundinacea, Potamogeton epihydrus, Nuphar variegata, Sagittaria latifolia, Utricularia vulgaris, Potamogeton pusillus, and P amplifolius

Thread-like naiad prefers sandy or silty soils and is found in oligotrophic lakes with soft water, often in calm, somewhat shallow water.

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.

Because this plant is an annual, work may safely be conducted before the plants emerge or after they have developed mature seeds.

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.
