About

The permanently waterlogged soils over most of the site have produced a variety of wetland communities representing various stages in ecological succession. Where the vegetation is grazed by cattle, diverse rush-pasture fen-meadow, tall-herb fen and swamp have developed, whist ungrazed areas support willow and alder carr. At the south end of the nature reserve, the lighter sandier soil supports drier grassland, similar to the hay meadows that would have once covered much of the Vale of York.
 
The site has many bird species characteristic of the farmed landscape surrounding the site, such as chaffinch, greenfinch and yellowhammer. Snipe may be found in winter, along with mixed flocks of lesser redpoll and siskin, whilst reed bunting are present all year round. Green woodpecker are a noisy inhabitant of the nature reserve.

Over 120 species of beetle have been found on the site, including the nationally scarce diving beetle Agabus uliginosus and the large click beetle Ctenicera pectinicornis, which is an important indicator of damp grassland.
