Counties with Mapped NHI Occurrences

Dune Goldenrod (Solidago simplex var. gillmanii), a Wisconsin Threatened plant, is found on semi-stabilized dunes along Lake Michigan. Blooming occurs early-August through early-October, fruiting late-September through late-October. The optimal identification period for this species is late-August through September.

Dune goldenrod is an erect forb, 3-9dm tall, with larger heads (6-9mm) in a long, often branched inflorescence with 7-10 rays. Fruits are short, hairy achenes. Leaves are basally disposed, the larger ones are narrowly oblanceolate to narrowly obovate, 2-30cm long and 4-40mm wide, toothed or sub-entire, generally acute, and often have irregular, fine hairs along the margins. Cauline leaves are progressively reduced, mostly lance-elliptic to oblanceolate or linear, the middle cauline leaves are not at all rhombic.

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

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

Associated species include Calamovilfa longifolia ssp magna, Artemisia caudata, Elymus canadensis, Calamagrostis inexpansa, Potentilla anserina, Elymus lanceolatus ssp psammophilus, Diervilla lonicera, Cirsium pitcheri, and Tanacetum huronense.

Dune goldenrod is found on semi-stabilized dunes along Lake Michigan.

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 disturbance to shorelines and the forest-beach interface.

Avoid any activities that destabilize the dune, including the use of off-road vehicles, removal of native vegetation, and pedestrian recreational overuse.

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.
