Eastern Candlewax Lichen (Ahtiana aurescens), a Wisconsin Special Concern lichen, is found on bark in a variety of northern forests, from spruce bogs to stands of old growth hardwoods.
Cetraria aurescens, Tuckermannopsis aurescens
Eastern candlewax lichen is a foliose lichen with apothecia that have maroon to brown flat or concave discs and occur mostly along the lobe margins. The thallus (vegetative body) is greenish-white or grey with shallow round lobes that are often wavy or wrinkled. The thallus underside is whitish to light brown, rhizines are short.

Soredia and isidia are absent.

Associates include black spruce, sugar maple, basswood, yellow birch, and white cedar.
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.
