2 points why sustainable management of woodland essential
1) To maintain biodiversity 2) To ensure timber companies are financially secure and can keep supplying wood
1 of 11
What is the small-scale timber production called and how does it happen?
Coppicing, the trunks are cut at the bottom to allow new shoots to grow and mature into stems that can be harvested
2 of 11
What are the quite narrow stems produced from coppicing used for?
Furniture, fencing and firewood
3 of 11
What is pollarding and why is it is done?
When the trunk is cut further up the trunk to allow the growth of new shoots - this is done when there are high numbers of deer in the population, it prevents them eating the new shoots as they cannot reach them
4 of 11
How do we ensure there is a continuous supply of wood from coppicing?
We use 'rotational coppicing' which is when the wood is divided into sections and each section is harvested at different time points (the period of time changes depending on the type of tree). This allows the tree's to fully mature
5 of 11
What are standards and what are they used for ?
They are trees that are left to grow larger without being coppiced and are used to supply larger pieces of timber
6 of 11
Why is rotational coppicing more beneficial for biodiversity than leaving the woodland unmanaged?
Because the tree's are cut down which means more light can get through to the flood of the wood and increasing the variety of species present

2 reasons how clear felling damages habitats and, as a result, is now rarely practised
1) It reduces the soil mineral and nutrient levels as there are no tree's to play a part in the carbon/nitrogen cycle 2) soil may run off into waterways and pollute them as there are no tree's to hold soil in place and absorb water
8 of 11
What are the three principles that modern sustainable forestry works by?
1) The local community must derive a benefit from the forest. 2) The harvested tree's must be replaced. 3) The ecology of the forest must be maintained (biodiversity, climate, mineral and water cycles)
9 of 11
What is selective cutting? Why is this beneficial to the habitat?
Only cutting down the largest and most valuable trees. This means the habitat is fairly unaffected.
10 of 11
Three methods which are practised in order to increase the yield from each tree
1) Pests and pathogens are controlled. 2) Only one type of plant is planted - they are usually well suited to the soil type. 3) The tree's are planted a set distance away from one another to ensure the best conditions for quality and efficiency

Report

To be sustainable implies that the woodland can be managed indefinitely. Without doubt the most common mistake among woodland owners on this is chopping, or pollarding, their woodland with Tree Pruning. The reason for this is that they see trees as wood. In fact, trees are a complex mechanism which involve all the different parts of the tree.
