A boreo-montane, rather continental, epiphytic species, growing mostly on branches of conifers. It is common in northern Eurasia, but rare in North America. In the past, Evernia divaricata was probably quite abundant in the Czech mountains, but as a consequence of air pollution, it markedly declined in the second half of the 20th century. At the end of the 20th century, it occurred only in the Šumava Mountains. Then its numbers have increased in the last decades. Besides mountains (Krušné hory, Krkonoše, Novohradské hory Mts), the species is occasionally reported at lower elevations, especially from Larix decidua monocultures, and Prunus spinosa and Crataegus sp. stands. In newly settled localities, however, usually only one or a few thalli are recorded.
