The habitats on the site are woodland, wet meadow and marsh, and it has one of the few areas of fen to survive in the area. There are three small woods, including Spring Wood, which has species indicative of ancient woodland. Locally uncommon plants in wetland areas include southern marsh-orchid, fine-leaved water-dropwort and golden dock. Insects include a rare bee, Macropis europaea, and 23 species of butterfly have been recorded.^[2] It is also a good site for water voles.^[1] A tributary of the River Ingrebourne runs through the site.^[3]
