Description

Description The woodlands of the lower Wye Valley form one of the most important areas for woodland nature conservation in Britain, comparable with the Caledonian pinewoods, the oceanic oakwoods of western Britain, the New Forest and the mixed coppices of East Anglia. Unlike most other regions, semi-natural woodland is abundant and virtually continuous along the gorge. The woods are a mixture of many types, some of which are very localised, e.g., the lime-sessile oak stands on limestone; beech stands on both acid and alkaline soils in which lime, elm, oak and other species share dominance. Most woods are a rich mixture of stand types, which are believed to be similar in composition to the original natural woods of the valley. Many rare and local species are present, including some of the rarest native tree species (e.g. large-leaved lime, whitebeams), and trees close to the edge of their European range, e.g., hornbeam, beech. Furthermore, these woods sit in a matrix of unimproved grassland and other semi-natural habitats which, together with the woods, make the Wye Valley one of the most diverse, rich and attractive areas of southern Britain. Cleddon Shoots Woodland is an area of predominantly acid woodland on the very steep east facing slopes of the River Wye Gorge near Llandogo. There are extensive areas of sessile oak Quercus petrea standards over beech Fagus sylvatica coppice, a woodland type and structure which is rare in the County. Ash Fraxinus excelsior and alder Alnus glutinosa are dominant along the stream, Cleddon Shoots, where the falls and flushes form an interesting additional habitat with a diverse bryophyte community. Remarks: Within the Wye Valley Area of Outstanding Natural Beauty. A Wildlife Trust Reserve.

Insects to look out for

These moths, butterflies and beetles are known to feed on plants recorded at this site, and carry a notable UK conservation status — but a host-plant being present doesn't mean the insect has actually been recorded here. Treat this as "worth watching for," not a confirmed sighting.
