Changes in agricultural land use have led to a drastic decrease in grassland and heathland habitat in Britain. This book presents an illustrated and practical guide to Britain's range of natural and semi-natural grasslands and heaths. It examines topics of concern to the ecologist or habitat manager such as causes of the loss and deterioration of these habitats, including inappropriate management, eutrophication and climate change. It then evaluates opportunities for positive change, such as conservation, restoration and creation. A series of case studies illustrates the pressures on some lowland grassland and heathland habitat types and looks at ways to enhance them for biodiversity.
