HorsetailThe north-east end of the site is occupied by a small area of woodland. This mixed, semi-natural woodland includes English oak, hornbeam and field maple on the drier ground, while ash, hazel and alder, together with some crack willow, occur on the stream sides. Holly, hawthorn and elder form a srub layer, and the small woodland shrubs rasberry, redcurrant and goosberry, all occur. The woodland is quite damp and the streamside vegitation is lush, supporting large bittercress which is a locally scarce wildflower.

Ancient woodland indicators have been found among the small woodland strip, which runs along the south-eastern boundary. Yellow archangel and wood anemone, as well as more wide spread species including lesser calandine, dog's mercury and wood avens have all been noted. Nearer the stream the trees have been coppiced, which has created a scrubby edge. Alder is abundant in this area, and the open conditions have allowed marsh species such as great horsetail, meadowsweet and pendulous sedge to spread.

The central marsh, an area of fen vegetation, is raised above the adjacent stream, and is fed by two seepages which arise in the pasture to the north west of the site. The area is not evenly wet througout, in fact some areas are relatively dry. Common-pipistrelleFalse oat grass, cocksfoot, cleavers and hogweed are found on the dryer areas, with rushes, meadowsweet, marsh marigold on the wetter. In the spring time the meadow is carpeted with ragged robin.

Survey work carried out in 1999 has shown the site to be fairly rich in insect life. Some rare species were found including the long-horn bee (Eucera longicornis) and a rare cranefly (Thaumastoptera calceata). The stream also proved to be rich in aquatic life. A small sensitive fish, the stone loach was found, indicating that the stream is clean and holds very little pollution.

The site has also been used by two species of bat, the common pipistrelle (Pipistrellus pipistrellus) and the soprano, or brown pipistrelle (Pipistrellus pygmaeus).
