| Founded in 1982, the Upper Thames Branch aims to protect butterflies, moths and their
habitats in the counties of Berkshire, Buckinghamshire and Oxfordshire. The Chiltern Hills,
the Oxfordshire/Berkshire Downs,
the Oxford and Aylesbury clay vales, the Bernwood Forest complex, the edge of the Cotswolds
and the Berkshire heathlands are all to be found in the three counties. | | Three-quarters of the fifty-eight British butterfly species can be found in the Upper Thames region, including the Black Hairstreak, Adonis Blue, Silver-spotted Skipper and Duke of Burgundy. Over 1700 moth species have been recorded, including Drab Looper, Striped Lychnis and Heart Moth. | | | The Branch is entirely run by volunteers.
