around 500 years ago and for much of its history has been used for farming. It was used as arable land and for grazing cattle, and at times for smuggling; the last inhabitants left the island at the end of the 1920s. In the 1930s it was used for summer grazing and in 1933 a gravel company set up shingle extraction on the island but this was found to be unprofitable and they soon left. During

the military took control of the island along with Orford Ness. Without human intervention during this time salt water flooded parts of the island making it unsuitable for agricultural use. Havergate Island was formerly an

and by 1961 the parish was unpopulated. On 1 April 1985 the parish was abolished and merged into Orford. In 1947 pied avocets were found on the island, as well as at nearby Minsmere, for the first time in the UK since they had become extinct in the country over 100 years before. A number of pairs bred that year on Havergate Island and raised eight chicks between them. Following this discovery the RSPB purchased the island in 1948 and have since managed it for the benefit of birds and the environment.
