Justification
Parmelia saxatilis is common and abundant in many forests, heaths, and uplands outside the tropics and does not qualify for any threat categories. It is, therefore, listed as Least Concern.Taxonomic notes
This species has been the subject of much recent taxonomic work, including splitting off the segregate species Parmelia ernstiae, P. serrana, P. mayi and P. rojoi (Feuerer and Thell 2002, Molina et al. 2004, Molina et al. 2011, Crespo et al. 2020), and investigations into the diversity in the genus (Divakar et al. 2016). None of these segregate species can be diagnosed confidently using morphology only (Corsie et al. 2019). Nevertheless, we suspect P. saxatilis s. str. remains an abundant macrolichen on rocks and trees throughout the northern temperate and boreal zone.Geographic range
This species is widely distributed across the temperate and boreal zones of the northern Hemisphere, in addition to South Africa, Patagonia, the Antarctic Peninsula, Southern Ocean islands and New Zealand.
Population and Trends
Parmelia saxatilis is one of the most common lichens in temperate and boreal habitats, and occurs in a wide range of settings (Molina et al. 2004). Even with the recently-recognized segregate species, recent molecular work has shown that P. saxatilis in the strict sense is found from pole to pole (Crespo et al. 2002, 2020). We infer the population size to be stable.
Population Trend: Stable
Habitat and Ecology
This species is abundant on trees and rocks (Brodo et al. 2001, Corsie et al. 2019) in a wide range of habitats across temperate and boreal biomes.Threats
This species may be sensitive to high pollution loads (Geiser and Neitlich 2007).
