Semi-natural Oak, Ash and Elm-dominated woodland

This woodland type is associated with wetter areas, generally in valley bottoms and on stream banks.

There is a canopy of Oak together with varying amounts of Ash; the latter becoming the dominant canopy species in some areas. The wettest areas of woodland often have Alder and Crack Willow. Although Elm was once an important species in this type of woodland, its population has been heavily reduced as a result of Dutch Elm Disease and the only Elms found in the canopy are now dead. As with the Oak and Birch dominated woodland, this woodland type contains occasional Sycamore and Beech of different ages. Some of the mature Oak and Ash are also likely to have been planted.

Most areas of this woodland type have a varied structure and a diverse understorey comprising young trees of Oak and Ash as well as Elder, Hazel, Elm and Guelder Rose. There is usually a rich ground flora, this being particularly the case by streams and on the wettest areas of ground. Ancient woodland indicator species such as Wood Anemone, Yellow Archangel and Bluebell are occasional to frequent.
