This book presents another milestone in our knowledge of butterflies in Berkshire, Buckinghamshire and Oxfordshire. A detailed survey of butterflies across the three counties over the period 1995-2000, has made possible for the first time the identification of changes and trends since a similar survey completed almost a decade earlier (1987-1992).
The changes reflect the damaging effects of further habitat loss and the warming effects of climate change. Habitat specialists are declining further-Pearl-bordered Fritillary and Small Pearl-bordered Fritillary appear to be extinct in the three counties and Marsh Fritillary is on the verge of extinction. In contrast, species at the limit of their European range in this area, such as Silver-spotted Skipper and Adonis Blue are faring better, as warmer climate improves their breeding success.
The book, richly illustrated with colour photographs and graphics, describes the trends for all of our local butterfly species, what is happening to key habitats and the continuing impact of climate change. It is a must for those with interests in butterflies, conservation and the countryside.
