Spring and autumnAbout the reserve
Semi-natural ancient woodland is a relatively rarity in Northumberland; this reserve is probably one of the best examples in the county. Ash dominates the reserve, although oak and birch are common. Typical ancient woodland plants are present including ramsons (wild garlic), woodruff and dog’s mercury, but there are a number of locally uncommon species including two regional rarities, bird's-nest orchid and wood fescue. Other uncommon plants such as herb Paris and toothwort are present along with a very good bryophyte flora and several rare, ancient woodland indicator lichens.
An area of the woodland planted with non-native species is being restored to provide suitable conditions for a range of rare species including dormouse which is found in neighbouring woodland, their most northerly location in the UK. You may also see red squirrel and roe deer as well as numerous birds including pied flycatcher and great spotted woodpecker.
There are remains of an old lead smelt mill near the River Allen. The grasslands have been contaminated by heavy metals derived from the Pennine orefield upstream. Plants indicative of this contamination include mountain pansy and alpine penny-cress.
There are no facilities on the reserve but The National Trust car park at Allen Banks has toilets and a picnic area.
