Abstract

Boreal felt lichen (Erioderma pedicellatum) is a rare lichen that is listed as critically endangered by the IUCN. On the island of Newfoundland, Canada, the Central Avalon Forest Ecoregion is a hotspot for this species. The population in this region is relatively abundant, providing an opportunity to study its habitat requirements. I used occupied and unoccupied plots (each 5 m radius) to test critical habitat for boreal felt lichen. To ensure I effectively detected lichens in our plots, I developed a decoy lichen experiment to test the detection probability of these lichens. I applied the results from the decoy experiment to the habitat study. Although I could not consider time in the study, I discussed how the shortened lifespan of the host tree may constrain the temporal niche of boreal felt lichen. I identified critical habitat for boreal felt lichen, which will contribute to informed land use to help protect this population.
