This document discusses different methods for using and maintaining trees, including shelterbelts, coppicing, and pollarding. It provides guidelines for selecting tree species for shelterbelts, noting characteristics like rapid growth, wind resistance, and drought tolerance. Suitable species mentioned include plum, dog rose, privet, and hazel. The document also briefly explains the differences between coppicing and pollarding tree maintenance techniques and presents a vision of "super trees" that could generate power and harvest rainwater.

- 2. Diversity of Trees Trees turn up on the scene some 400 Million yrs ago
- 4. Windbreak
- 5. Shelterbelt - Windbreak Also known as a wind break a shelter belt is a living barrier consisting of rows of trees and shrubs to mitigate wind speed in a given location.
- 6. Selection of Species - Local plants - Rapid growth; - Wind firmness; - Good crown formation; - Deep root system, which do not spread into nearby fields; - Resistance to drought; - Evergreen species for year round protection - Multiple outputs- Forage - fuel wood - mulch – timber

- 8. Coppicing Benefits include Promoting ground and undergrowth vegetation- designed disturbance (by letting light in) Raw materials for thatching, fencing, kindling and charcoal making. All deciduous trees can be coppiced, but hazel, ash, lime,sweet chestnut and beech are common.
- 9. Pollarding The difference between a Pollard and a Coppice is that Coppice's are cut to ground level whilst Pollards are cut to a height over 2metres tall.
