Parsonage Moor and Cothill Fen


Join Oxfordshire Reserves Officer, Lucy Garrod, for a walk around Parsonage Moor and Cothill Fen. Cothill Fen Site of Special Scientific Interest is the largest remaining area of alkaline fen in central England. This is an exceptionally important site with an outstanding range of nationally rare habitats supporting a large number of rare invertebrates and plants. Cothill Fen supports over 330 species of vascular plant and over 120 nationally scarce or rare invertebrates, including the nationally rare Southern Damselfly (Coenagrion mercuriale).

Lucy will explain how BBOWT manages the different habitats within the reserve. She will tell us about some of the threats to calcareous fens, and about some of the special species the site supports. We are hoping to find the beautiful Grass of Parnassus still in flower. This species is rare in southern England, occurring in only two or three other calcareous fen sites in Oxfordshire, and in the Norfolk Broads, and in fens in Anglesey.
