Lichens on a Sessile Oak, Quercus patreae. Fairlight Glen. 05.03.24


Habitat: High Weald ancient woodland; oceanic micro-climate in a steep High Weald ghyll. In Fairlight Glen there is the famous Dripping Well waterfall - the only location of Dumortier's Liverwort, Dumortiera hirsuta, east of Devon). The ghyll carves a ravine out of the rocks of the Tunbridge Wells series, where they meet the see.
