They lie adjacent to the lower, tidal part of the River Wye, and are unique in Gloucestershire. The area is made up of a collection of fields which are crossed by rhines and water-filled ditches. This pastureland, which is flooded by spring tides (the Wye being a tidal river), is traditionally grazed in the summer months.[1] FloraMud rush, meadow barley, red fescue, marsh foxtail and the nationally rare bulbous foxtail flourish in the pasture. There is a variety of saltmarsh plants such as sea arrowgrass, sea milkwort, sea aster, greater sea-spurrey, and lesser sea-spurrey. The rare narrow-leaved marsh dandelions (Taraxacum palustre and T. anglicum) are also recorded. Where areas become marshy grassland other species are found. The drainage ditches support a separate range of plants. The brackish water-crowfoot (Ranunculus baudotii) may be found at the boundaries of some of the fields.[1]FaunaRedshank and lapwing breed on the site. Several species of damselfly flourish along the draining ditches include the azure damselfly.[1]References1. ^1 2 3 Natural England SSSI information on the citation 2. ^Forest of Dean District Local Plan Review, adopted November 2005, Appendix D 'Nature Conservation Site Designations Within the Forest of Dean District', Sites of Special Scientific Interest 3. ^Forest of Dean District Local Plan Review, adopted November 2005, Appendix D 'Nature Conservation Site Designations Within the Forest of Dean District', Key Wildlife Sites External links
