Q

Managing woodland has two effects on climate change:

A
  1. Resilience - Establishing mixtures of trees bearing in mind the changes in climate will increase the rate at which woodlands can change and increase the ability of ecosystems to react to changes.
  2. Mitigation - effective and efficient ways of removing atmospheric carbon. Timber a good replacement of building materials such as steel. Can control and contain flooding and erosion. Shelter belts to fields.
