Grasslands of Wales provides a thorough account of the vegetation of species-rich grasslands in lowland Wales at the end of the 20th century. It sets out the findings of 18 years of research and survey of all significant stands of agriculturally unimproved lowland grasslands and their associated vegetation.
This magnificent volume is an essential buy for anyone with a serious interest in the vegetation of Wales. It is clearly written and beautifully illustrated with attractive and relevant pictures of both landscapes and individual plants. One of the recurring themes of nature conservation is the need for 'base-line' studies against which future monitoring of the state of our environment can be measured. Grasslands of Wales is an exemplar of how such studies should be executed and presented. It represents the results of many years of painstaking and original research.

The book provides detailed descriptions of all the lowland grassland, mire and heath vegetation types of Wales in a very clear and logical format, and then goes on to discuss the complex ecological interactions between plant communities and the environment. A number of site 'pen pictures' are a useful addition, giving a feeling for the distribution of habitats in defined areas such as the Great Orme or Roundton Hill.

Since it was commissioned in 1975, the National Vegetation Classification has become the standard for describing floristic diversity in Britain. This book not only expertly utilises the classification, but enhances, elucidates and informs its use, especially by illustrating the main plant communities described. For this reason alone it will attract buyers from far beyond Wales.

Although a technical report, Grasslands of Wales will appeal to anyone with a strong ecological interest. Overview sections at the end of the chapters clarify some of the technical detail for more general readers. This is particularly true of Chapter 9 ('Vegetation Analyses'), the detail of which is highly statistical, and of Chapters 10 and 11 on 'Patch Characteristics' and 'Environmental-vegetation Relationships' respectively.

As a former soil surveyor, I have to admit to some disappointment with Chapter 12 ('Soil-vegetation Relationships'), which does a reasonable job, but does not relate the plant communities to soil types mapped on the National Soil Map. But this is a minor grouse related to my own interests.

Overall this book is a major achievement for its authors and their organisation. They have every right to be proud of it as a fitting tribute to the late David Stevens who led the project. It will serve as a wonderful reference on Welsh vegetation, which is such an important element of the landscape.

Bywgraffiad Awdur:
The authors worked as part of the Terrestrial Science Group of the Countryside Council for Wales, the successor body to the Nature Conservancy Council for Wales, during the preparation of this book.

Until his untimely death in 2007, David Stevens co-ordinated the Lowland Grassland Survey of Wales.

Stuart Smith spent several years undertaking grassland field survey, and has since had a major role in compiling the survey findings.

Tim Blackstock is head of the group and has overseen the grassland survey since its inception in 1987.

Sam Bosanquet participated in the final phase of fieldwork on the grassland survey, and has played a key role in analysing the spatial dataset.

Jane Stevens has organised the database with the survey findings and undertook vegetation data analysis.
Gwybodaeth Bellach:
Such wildlife-rich grasslands have been widely replaced by much less diverse rye-grass swards. The survey covered 1070 sites of varying size and pioneered the use of the National Vegetation Classification for identifying and mapping vegetation at a regional scale. Over 150 different vegetation types were recorded, and this book characterises their forms and relationships, and extent and distribution within species-rich grasslands in lowland Wales.

Grasslands of Wales includes detailed phytosociological floristic descriptions, extent data and distribution maps of lowland grassland plant communities and sub-communities, with critical comments on how each differs from similar plant communities and what vegetation types each is typically associated with in the field. Quadrat records are summarised in synoptic tables. Technical analyses of the data are presented giving insights into community distribution patterns and associations. New information on the physical and environmental characteristics of lowland grassland communities within Wales is assembled, and data on soil characteristics of Welsh lowland grasslands and associated flush communities are given in detail. Also reviewed in this book are the rare and uncommon plant species associated with lowland grasslands in this part of western Britain. The authors have worked for most of their careers in applied conservation biology, and a strong conservation current runs through the book.
