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. Harper’s Grove – Lord’s Grove is a large area of predominantly relict mixed coppice and mixed coppice with standards of woodland on the steep west -south-west facing slopes of the River Wye gorge south of Monmouth. There are a large number of woodland types with extensive areas of oak Quercus robur and Quercus petraea, small leaved lime Tilia cordata and beech Fagus sylvatica. The site is notable for a stand of hornbeam Carpinus betulus which appears to be the only truly natural stand in the county and is a considerable distance from its main area of distribution. Large leaved lime Tilia platyphyllos also occurs in Lord’s Grove. Remarks: Within the Wye Valley Area of Outstanding Natural Beauty.

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.
