This hardback book is the culmination of over four year's research and survey work by Martin Sanford of the Suffolk Biological Records Centre. Several thousand records, most supplied by amateur naturalists, have been analysed with the help of sophisticated computer programs and used to plot accurate distribution maps. High quality colour photographs of each species with accompanying notes enable the book to be used as an identification guide. There are introductory sections on ecology, variation, habitats and conservation, and a special feature 'Suffolk orchids, half a century of change' by Francis Simpson, author of Simpson's Flora of Suffolk.
