PROTECTING WISCONSIN'S BIODIVERSITY

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

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

Associated species include Bouteloua curtipendula, B hirsuta, Sorghastrum nutans, Polygala verticillata, Ambrosia artemisiifolia, Andropogon gerardii, and Euphorbia corollata.

Arrow-headed rattle-box is found in dry prairie areas, but habitat requirements are not well-understood. It has also been documented along a sandy lakeshore.

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.

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.

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.
