Devon hedge bank
Devon hedges comprise an earth bank topped with hedgerow shrubs. The bank may be faced with turf or faced with stone. If stone-faced, the stones are generally placed on edge, though around gateways the stones are often placed flat.
A quarter of Devon's hedges are thought to be over 800 years old. There are approximately 33,000 miles (53,000 km) of hedge in Devon, more than any other county, though this is not all of Devon hedgebank construction. This is because the traditional farming throughout the county has meant that fewer hedges in Devon have been removed than in other counties.
Devon's hedges are particularly important for wildlife habitat. Around 20% of the UK's species-rich hedges occur within Devon. Over 600 flowering plants, 1500 insects, 65 birds and 20 mammals have been recorded living or feeding in Devon hedges.
