undrained, realising their ornithological value. RSPB era The RSPB had been considering the Minsmere site, at that time about in extent, as a potential reserve from the late 1930s, and a management agreement was signed in 1947. The appointment of Bert Axell as warden in 1959 led to major changes in reserve management, which were in due course also adopted elsewhere. He realised that ecological succession would eventually lead to the loss of important habitats, such as bare ground on the heaths or open water in the reed beds, unless natural plant colonisation was actively prevented. He created the "scrape", an area with shallow water, islands and bare mud, by lowering land levels and managing the water level with new sluices. A circular path led around the scrape, giving access to hides on each of the four sides. In 1977, two years after Axell's retirement, the RSPB purchased the reserve outright. The Great Storm of 1987 destroyed 3,000 trees in one night. Many areas were reforested, but it was noticed that other badly affected woodlands nearby were colonised by woodlarks, so some recently acquired arable land was acidified and converted to heathland to encourage open-ground species. Minsmere is one of a small number of UK sites at which bitterns breed. In 1979, nine booming males were counted but the population at Minsmere has varied over time, reaching a low of only one booming male in 1991. During the 1990s the existing reed beds were managed specifically for bitterns; when grazing marshes known as the North and South Levels were purchased, the North Levels were converted to reed bed and the South Levels to wet grassland. The Minsmere reserve covers about of reed bed, open water, lowland heath, grassland, scrub, woodland, dune and shingle vegetation. The nature reserve, its habitats and wildlife, are protected under UK law as part of Minsmere–Walberswick Heaths and Marshes, which is a Special Protection Area, a Ramsar Site, a Special Area of Conservation and a Site of Special Scientific Interest. The site is also included in the areas covered by the Suffolk Coast and Heaths Area of Outstanding Natural Beauty (AONB) and the Suffolk Heritage Coast. Access and facilities The reserve is accessible by car from the A12 via the village of Westleton. It is also connected to Route 1 of the Sustrans National Cycle Network by the Suffolk Coast Cycle route. The nearest bus access
