Counties with Mapped NHI Occurrences

Clustered Poppy-mallow (Callirhoe triangulata), a Wisconsin Special Concern plant, is found in sand terrace prairies. Blooming occurs early-July through late-September, fruiting early-August through late-September. The optimal identification period for this species is early-July through September.

Clustered poppy-mallow is an erect forb, 40-100cm tall, that grows in a gently sweeping upward manner. It has flower stalks that bear several flowers, each flower has 3 leaf-like bracts at its base and 5 red to bright pink petals 16-32mm long with a white spot at the base. It has several, short-stalked, heads borne on the ends of longer branches. Mature carpels are rounded or short-beaked, hairy but not rugose and contain 1 seed. Leaves are triangular to heart-shaped and edged with rounded teeth. The lower leaves have long petioles, the upper leaves tend to be much narrower. Its stems are covered in many stellate hairs.

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

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

Associated species include Amorpha canescens, Andropogon scoparius, Stipa spartea, Euphorbia corollata, Carex muhlenbergii, and Quercus velutina.

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 locating landings, staging areas, or access routes in open sandy areas dominated by native grasses.

Prescribed burns and/or brushing may be beneficial, dependent on local site conditions and burn frequency. Rotational burns with annual unburned refugia may be preferred.

Maintain and restore open habitat through selective clearing and brushing.

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.
