Natural depressions in the glacial drift left by the ice sheets which covered the Cheshire–Shropshire plain during the last ice age, 10,000–15,000 years ago, filled with water, forming the meres and mosses characteristic of the area today. In some cases, like Risley Moss, peat accumulation filled the depression, allowing colonisation by bog mosses such as the Sphagnum varieties, thus giving rise to the name "moss".
Risley Moss is one of only two mosses in Cheshire where the water level has been deliberately raised in an attempt to encourage the regeneration of an active bog surface.[1] The long-term restoration project to re-wet the moss began in 1978 and was completed in 2002. This scheme was undertaken to create a series of scrapes and bunds to retain water and recreate the perfect conditions for bog flora such as cotton grass and sphagnum mosses to re-colonise the bogs.[5]
Risley Moss was first mentioned in the Doomsday Book when it was part of the Culcheth Estate. The Moss passed to his daughter Ellen de Risley and remained in her family until 1736 when it was bought by a local landowner. During the Industrial Revolution many of the peat bogs near Manchester were drained however Risley was too wet and remained under water.[6]
The main feature of Risley Moss is the large peat bog, overlooked by two observation points: a raised platform (previously having a large watchtower) ideal for bird watching, and a smaller lookout (currently obstructed by plant growth). These points have additional information inside relating to bird species and landscape layouts. The Moss also has several smaller huts located inside the forested area for bird watching and nature enthusiasts. Tours across the bog and nature reserve are available from the main information centre and are undertaken by local rangers.
In addition to the natural features and landscape, there are several sculptures around the site, usually with a natural theme.
