Thames Basin Heaths

Year of compilation: 2007

Site description
The IBA contains several widely separated fragments of what was once an almost continuous block of heathland in the Thames basin. It includes much of the remaining heathland and mire in Surrey, north-east Hampshire and south Berkshire. The habitat mosaics comprise acidic grassland and heathland, and areas of invasive Ulex, Betula, Quercus and Pinus sylvestris. The IBA holds important breeding populations of specialist heathland birds.
