PROTECTING WISCONSIN'S BIODIVERSITY

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

Perennial. This species can be identified year-round.

Associated species include Picea mariana, Abies balsamea, Betula papyrifera, Sorbus decora, Thuja occidentalis, Ledum groenlandicum, Linnaea borealis, Alnus viridis, Cornus stolonifera, Vaccinium angustifolium, V oxycoccos, and Gaultheria hispidula.

Mountain cranberry prefers acidic, loamy soils and is found on mossy cliffs along Lake Superior and in conifer swamps inland.

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.

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.

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.

Minimize disturbance to hydrology, including soil disturbance from rutting.

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.
