Sand Loving Iceland Lichen (Cetraria arenaria), a Wisconsin Special Concern lichen, is found on sandy or thin soil in a range of habitats, including dunes, prairies, and sandy forests.

 
 
 

Sand loving Iceland lichen is a folios lichen with red-brown apothecia that are uncommon. The is light green, pale blue-green, or even reddish brown, and erect or tufted. The lobes are narrow linear, often involute and with pseudocyphellae (thallus pits or cracks) and ciliate margins.

The involute margins of the thallus branches may give sand-loving Iceland lichen the appearance of a fruticose lichen. This species can be distinguished from others in the genus by its flat or involute (but not terete) branches, marginal pseudocyphellae and cilia, and greenish (vs tinges of yellow or red) hue.

Sand loving Iceland lichen is found on sandy or thin soils in a range of habitats, including dunes, prairies, and sandy forests.

On dunes, associates include Juniperus communis and Arctostaphylos uva-ursi, in prairies Krigia virginica, Panica virgatum, Stipa spartea, Boteloua hirstua, Schizachyrium scoparium, and Selaginella rupestris, and in forests Pinus species.

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.
