Welcome to the Upper Thames Branch of Butterfly Conservation

Founded in 1982, the Upper Thames Branch aims to protect butterflies, moths and their habitats in the counties of Berkshire, Buckinghamshire and Oxfordshire. The rolling hills of the Chilterns, the Oxford and Aylesbury clay vales, the ancient Bernwood Forest complex, the edge of the Cotswolds and the heathlands of south-east Berkshire are all to be found in the three counties. Several rare species of lepidoptera can be found in the region, including the Black Hairstreak, Adonis Blue, Silver-spotted Skipper and Duke of Burgundy butterflies, and the Striped Lychnis and Heart moths.
