Lichens on worked wood (fence rails). St Mary the Virgin churchyard. Friston. East Sussex. 22.05.24

 "Worked wood" (e.g. fences, fence posts, gates etc.) can be a great substrate for lichens.

Cladonia portentosa, Reindeer Lichen

I've only seen it on lowland heaths in Sussex before. But perhaps the wood is so well-rotted it is like soil to the Cladonia

Lichens of Selwyns Wood (Sussex Wildlife Trust), Cross-in-Hand, East Sussex. 07.05.24

Selwyns Wood is a small nature reserve south of Cross-in-Hand, near Heathfield, East Sussex.

Selwyns Wood is a small, mixed semi-natural woodland near the town of Heathfield, mainly Oak, Birch and Sweet Chestnut, with a few old big Beech trees. It is nestled in a south-facing valley with three streams running through it, one of which has developed into a typical Wealden ghyll stream. There is also a small open area dominated by heather, a characteristic feature of woodlands in this part of Sussexfrom Sussex Wildlife Trust Selwyns Wood Reserve Profile

Lichens on three Wild Service Trees, Torminalis glaberrima, in woods north-west of Cow Fold, 16.04.24

I examined three Wild Service Trees near Cowfold. All three had the same lichen community growing on them.




Habitat: Low Weald ancient woodlands on clay. Ancient woodland status suggested through presence of Yellow Archangel, Bluebells, Wood Sedge, Midland Hawthorn, and Wild Service Trees

This map showing the location of these tress is from Dave Bang's The Land of the Brighton Line: A field guide to the Middle Sussex and South East Surrey Weald (2018)
