Bryophytes & Lichen of the Francis Rose Reserve/Wakehurst Wood part of the Wakhurst and Chiddingly Woods SSSI 18.03.18

I visited Kew's Wakehurst not to look at epiphytic bryophytes and lichens on the introduced trees and plants of its botanical gardens but to see the lichens and bryophytes in the large amount of indigenous high weald ghyll woodland, especially the Wakehurst Wood area of Kew's Wakehurst estate, part of the Wakehurst & Chiddingly Woods SSSI 


Ecology:

The wooded ghylls have been formed by streams cutting through formations of Wadhurst clay and Lower Tunbridge Wells sands, leaving exposed outcrops of sandstone in the valleys. The warm, moist micro-climate allows plants to flourish which are more typically restricted to the west of the country. The streams have been dammed to form a series of ponds with marginal vegetation which contribute to the value of the site for birds. Much of the woodland is semi-natural, but in some areas conifers and rhododendron have been planted. The sandrocks in Wakehurst and Chiddingly Woods support rich communities of ferns, bryophytes (mosses and liverworts) and lichens. These are a remnant of a Western ‘Atlantic’ plant community which was once far more widespread in distribution. They include uncommon plants such as the Tunbridge filmy fern Hymenophyllum tunbrigense, bryophytes such as Dicranum scottianum, Orthodontium gracile, Tetrodontium brownianum, Scapania gracilis and Blepharostoma trichophyllum, and some lichens of county importanceWakehurst & Chiddingly Woods SSSI 

Part of the Wakehurst Wood area of the SSSI is called the Rock Walk, where the Ardingly Sandstones of the Tunbridge Wells series are the home of many cryptograms, this is called the Frances Rose Reserve, after one of Sussex's most important bryologists and lichenologists. 


Here are the species I saw either on indigenous trees, the Ardingly Sandstone, on the ground or in/around the ghylls. Some of these identifications may not be correct; I am still new to bryophytes and lichens, so please do correct me in comments on this post

I am grateful to receive corrections if I have made an identification error.

I visited Walk Wood and St Mary's Churchyard in Balcombe with a friend who is an expert lichenologist. All of these identifications were...
