PROTECTING WISCONSIN'S BIODIVERSITY

Rhizomatous. Fruiting occurs mid- to late-summer.

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

Associated species include Acer saccharum, Betula alleghaniensis, Tsuga canadensis, Ostrya virginiana, Athyrium angustum, Quercus rubra, and Adiantum pedatum.

Male fern prefers moist soils and is found in mesic hemlock-hardwood forests, often on rocky basaltic slopes.

Avoid broadcast spraying of herbicides and use care with spot spraying.

Avoid site preparation that heavily disturbs herbaceous ground layer and soil, including bulldozing and furrowing, as well as grubbing and stump removal.

Avoid direct disturbance to sensitive microsites such as seeps, cliffs, and moss-covered boulders.

This species overwinters above ground, meaning that seasonal restrictions like conducting the a project on frozen ground will not result in avoidance. Therefore, known individual plant locations should be avoided year-round. Consult with a biologist, if needed.

This species requires shaded habitat conditions, maintain high forest canopy cover.

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.
