Why is roundwood durable?
• Unbroken fibres do not allow water penetration
• Nilapuu!

Energy use
• Manually processed roundwood has very low energy use
• Positive environmental impacts:
• Habitat / biodiversity
• Carbon sequestration

Chestnut palings
• Attractive
• Very durable 40years!
• Small businesses
• Multifunctional forest management / biodiversity
EURIS – Europeans Using Roundwood Innovatively & Sustainably
Silviculture• Chestnut Pales are
harvested from coppices situated in Kent and Sussex.
• Coppicing is an ancient forest management system whereby the growing tree is cut back to ground level every 15 years, leaving what is known as a stool.
• The tree then puts out new shoots, up to as many as 12, which can be commercially harvested at the end of the 15 year growing cycle.
• Small coupes – multi-structured woodland
EURIS – Europeans Using Roundwood Innovatively & Sustainably
Environment• Coppice woodlands provide excellent habitat, supporting often very
specific species• Some stools are up to 500 years old, making them some of the
oldest living plants in the UK. • Coppices flourish on poor ground and therefore are important to the
rural economy, both in terms of land usage and employment.• Integral feature of the local landscape

Harvesting
• Motor manual harvesting• Small coupes (less than 1 hectare)• Low impact / low tech extraction• Pole length

UsesEither permanent or re-useable fencing situation such as:
• Around a building or civil engineering site.
• Tree and planted area protection.• Hazardous areas. • Parks, gardens and Country
Estates.• Crowd control.• Temporary car parks and access
ways.• Erosion control of beaches.• Snow drift control.
