Abstract
In a recent study in Freshwater Forum on Speakman's Pond (also known as Nursery Pond) the impression was given that it had been a permanent water-filled pond which had recently dried out due to exceptionally low rainfall. In fact, Nursery Pond was created by the extraction of gravel and was never more than 50 cm deep, until the creation of trenches in 1989 to provide a refuge for aquatic life. The Nursery Pond followed a seasonal pattern of filling with winter rain and slowly drying out between 1940 to 1970. It had no established aquatic vegetation, no fish, and only rarely amphibians. Permanent water was present only from about 1979 until 1995 due to leakage from a Thames water storage reservoir.
