COSEWIC Assessment Summary and Status Report: Vole Ears Erioderma mollissimum

Assessment Summary – November 2009

Common name
Vole Ears

Scientific name
Erioderma mollissimum


Reason for designation
This large foliose lichen is known in Canada only from Nova Scotia, New Brunswick, and the island of Newfoundland, where it inhabits cool, humid and coastal conifer forests dominated by Balsam Fir. Although there are 24 known sites for the lichen in these regions, few individuals (133 thalli) are known. While recent surveys have increased the number of known locations, the lichen has been extirpated from 11 sites in the last 30 years. This lichen is a sensitive indicator of air pollution and acid precipitation, which are its main threats. Other threats include forest harvest and browsing by moose.

New Brunswick, Nova Scotia, Newfoundland and Labrador

Status history
