Reversing the habitat fragmentation of British

Originally, natural forests covered perhaps 85-90 per cent of the land, but by the 11th century, clearance had reduced them to 15 per cent in England. Today, the remnants – the ancient woods – cover no more than 1.4 per cent of ...

Restoration ecology
Restoration ecology emerged as a separate field in ecology in the 1980s. It is the scientific study supporting the practice of ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action. The term ""restoration ecology"" is therefore commonly used for the academic study of the process, whereas the term ""ecological restoration"" is commonly used for the actual project or process by restoration practitioners.
