Higher altitudes, and differing rock types/exposure levels can facilitate the growth of distinct lichens and mosses from those found in low country and woodland environments. These lichens were seen on an upland ridge at #TheLawley in #ShropshireHillsAONB #UK today. Silvery pale acid greens and silver tones may be a defensive strategy to mitigate the effects of high winds and exposure to sunlight. #LichenSubscribe
