PROTECTING WISCONSIN'S BIODIVERSITY

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

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

In Wisconsin, it's noted to be parasitic on Corylus, Agalinis, Asclepias syriaca, Helianthus, Solidago canadensis, and members of the Lamiaceae family. In Michigan, it's known to parasitize Mentha, Euthamia, Aster, Stachys, Ceonothus, Amphicarpeaea, Bidens, Mondarda, and Symphoricarpos.

Hazel dodder is found in sandy lake margins, wet-mesic areas, mud flats and moist fields, and in one instance, a prairie.

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.

Avoid disturbance to shorelines and the forest-beach interface.

Minimize disturbance to hydrology, including soil disturbance from rutting.

Maintain partial canopy to encourage woodland species, avoid closed-canopy conditions.

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.
