PROTECTING WISCONSIN'S BIODIVERSITY

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

Annual. The optimal identification period for this species is early-August through early-September.

Associated species are primarily Potamogeton species.

Large water-starwort prefers wet soils and is found on muddy shores, pools in swift streams, and wet sand along creeks.

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.

Minimize disturbance to hydrology, including soil disturbance from rutting.

This species is likely sensitive to water quality. Following BMPs around streams and buffering associated drainages will reduce eutrophication and prevent water quality degradation.

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.
