Fir Clubmoss (Huperzia selago), a Wisconsin Special Concern plant, is found on moist, shaded cliffs on the Lake Superior shoreline. It has also been found inland in a black spruce/balsam-fir swamp. This species can be identified year-round.

Fir clubmoss is a fern ally with sporophylls that resemble the vegetative leaves, 1-1.5mm wide, spores 32-38 microns in diameter, with concave sides and smooth commissural faces. Its sterile leaves are usually ascending, equal size throughout, in about 8 ranks, broadest at or near the base, gradually tapering to a sharp point at the tip, entire, glossy, 3-5mm long by 0.6-0.8mm wide, and often with axillary buds.

It can be distinguished from H lucidula by its entire leaves (rather than leaves that are toothed at the tip) and from H appalachiana by its annual growth constrictions and longer leaves.

Associated species include Primula mistassinica, Abies balsamea, Betula papyrifera, Thuja occidentalis, Sorbus decora, Ledum groenlandicum, Cornus stolonifera, Alnus viridis, Campanula rotundifolia, and Agrostis hyemalis.

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

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.

Avoid disturbance to shorelines and the forest-beach interface.

Follow BMPs, especially around streams and use care near ravines, steep slopes, cliffs, rock outcrops, etc.

Buffer management around unique microhabitats such as ephemeral ponds, seeps, etc.

Minimize disturbance to hydrology, including soil disturbance from rutting.

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.
