|IPA Factsheet - Avon Gorge|
Site Description Avon Gorge is an example of Tilio-Acerion forest in south-west England; here found on the limestone cliffs and scree slopes of a large river gorge. The Avon gorge is of ecological importance for a number of reasons. It contains habitats suitable for uncommon plants, such as green hellebore Helleborus viridis, fly orchid, Ophris insectifera, and honewort, Trinia glauca.. There is a high concentration of small-leaved lime Tilia cordata and small groves of yew Taxus baccata also occur on some of the stonier situations. Species-rich transitions to scrub and grasslands are associated with the woodland. The Avon gorge is a sorbus hotspot, containing many rarities and 2 endemic species.The unique landscape varies from mixed woodlands and grasslands of great interest to rugged rock faces, which plunge down to a glistening river. The cliff faces are home to rare wildflowers such as the Bristol rock-cress Arabis scabra and Bristol onion Allium sphaerocephalon
Botanical Significance Noted for vascular and habitat interest. Two of the Sorbus species are endemic to the Gorge and surrounding woodland.
