Counties with Mapped NHI Occurrences

White Camas (Anticlea elegans ssp. glaucus), a Wisconsin Special Concern plant, is found in a variety of habitats, including oak openings, wet-mesic calcareous prairies, limestone-capped sandstone bluffs, cliffs, outcrops, and stabilized dunes along Lake Michigan. Blooming occurs late-May through late-July, fruiting mid-August through early-September. The optimal identification period for this species is late-May through July.

White camas is an erect forb, 3-8dm tall, with a tall panicle of 6-parted white petal-like tepals, usually purple beneath and with green or yellow spots near center. Its fruit is an ovoid capsule 10-15mm long, barely exceeding the persistent perianth. It has narrow to broadly linear leaves, 2-4dm long and up to 12mm wide, attenuate, and crowded toward the base of the plant.

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

Perennial. The optimal identification period for this species is late-May through July.

For the Lake Michigan locations, associated species include Juniperus horizontalis, Prunus pumila, Carex crawei, C garberi, C viridula, Lobelia kalmii, Arabis lyrata. For the prairies and savannas, associated species include Quercus species, Carya ovata, Rhus glabra, Amorpha canescens, Solidago nemoralis, Schizachyrium scoparium, Andropogon gerardii, Bouteloua curtipendula, Aster sericeus, Dalea purpurea, and Liatris aspera.

White camas is found in a variety of habitats with moist, calcareous soils, including oak openings, wet-mesic calcareous prairies, limestone-capped sandstone bluffs, cliffs, outcrops, and 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.

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.
