Oliver Rackham was an academic at the University of Cambridge who studied the ecology, management and development of the British countryside, especially trees, woodlands and wood pasture. His books included Ancient Woodland (1980) and The History of the Countryside (1986).

A woodland is, in the broad sense, land covered with woody plants, or in a narrow sense, synonymous with wood, a low-density forest forming open habitats with plenty of sunlight and limited shade. Some savannas may also be woodlands, such as savanna woodland, where trees and shrubs form a light canopy.
