Macrolichens of Forillon National Park, Quebec, Canada.

Forillon National Park (Forillon) is on the Gaspé Peninsula in Quebec, Canada. It covers c. 245 km2 at the northernmost tip of the peninsula and is part of the continental terminus of the Appalachian Mountains in eastern North America, which extends from Alabama in the United States to the island of Newfoundland in Canada. The southern portion of this mountain range is a well-documented hotspot for lichen diversity, but lichens in the northern portion, on the Gaspé Peninsula, are not as well understood. To address this knowledge gap, we completed a detailed survey of the macrolichens of Forillon. The park contains a remarkable diversity of habitats and microclimates, due to its unique geography and geology. This includes coastal environments in marine and freshwater habitats, exposed calcareous cliffs, boreal and Acadian forests, and a taiga environment, which makes colonization possible for a wide range of lichen species. Using the floristic habitat sampling method, we discovered 161 macrolichen species, including new provincial records and major range extensions. Our results contribute to a better understanding of the lichen diversity in Quebec, eastern Canada, and the Appalachian Mountains. They also provide a baseline from which future changes can be monitored.
