Q

What is coppicing?

A
  • cutting the stems at ground level
  • thinner stems regrow
  • provides lots of thin sections of wood which are ideal for firewood
2
Q

What is polarding?

A

It is like coppicing but carried out higher up the trunk so that areas with dear cannot reach the young shoots that are growing

Q

How can woodland ecosystems be managed to provide resources in a sustainable way?

A

• trees are cleared in strips or patches
- woodland grows back more quickly in smaller areas between bits of existing woodland than it does in larger open areas
- cleared strips aren’t too large or exposed so soil erosion is kept to a minimum so newly planted trees are able to grow
• only native species are planted as they grow more successfully as they’re better adapted to climate
• coppicing or polarding
• planted trees are attached to posts to provide support and are grown in plastic tubes to stop them being eaten by grazing animals
- makes it more likely that trees will survive to become mature adults
• harvest timber from a different part of the woodland each year and rotate the area used to avoid clearing one huge area
- wider range of habitats is maintained
