Arger Fen and Spouse's Vale is a fascinating mosaic of ancient woodland alongside fen meadow and regenerating woodland. The interesting mix of trees at Arger Fen includes oak, ash, field maple, holly, crab apple, superb large alder, hazel stools and wild cherry. The reserve's contrasting habitats of dry wooded hillside and damp valley floor create a rich environment for wildlife and visitors alike. Many rare and declining species find refuge here including the scarce hazel dormouse and the barbastelle bat. Common lizards and grass snakes bask in woodland glades in summer, butterflies to look out for include speckled wood, meadow brown, orange tip, holly blue and comma.
