What damages tree roots?
Mature trees are particularly susceptible to root damage; so any activities around the roots of trees need to be carefully considered in order to minimise this. A tree stays upright in the same way as a wine glass does, i.e. the roots form a plate or base usually at least the same width as the crown. Few trees have a significant “tap root”.
Given this support mechanism any trenching works that pass close to the stem of the tree are likely to cut off nearly half of its support. If the trench is then filled with a concrete foundation the tree will be unable to replace this root system. Root systems not only provide stability but also absorb water and nutrients, so loss can also lead to drought and starvation.
Compaction of the soil around roots destroys the soil structure and stops the flow of water / nutrients within the soil, whilst also preventing gaseous exchange ("breathing”) which is vital to root survival. Therefore, you should avoid regularly driving vehicles over the root plate or any other actions which may lead to compaction of the soil (such as the storage of heavy items). Tree roots may also be directly crushed by the movement of heavy vehicles etc.
Herbicides and other toxic or chemically active materials (such as diesel oil) will also cause damage or death if they come into contact with a tree or its roots.

Does ivy damage trees?
Ivy is not a parasite. Ivy plants derive all their nutrients and water through their own root system and only use trees for support. If ivy was parasitic then it would be unable to survive on dead trees or walls. Ivy has a very high wildlife value, as it provides both habitat and food for a wide range of birds, insects and animals. Ivy may however constrict the stem growth of saplings and can cause stability problems to very over-mature trees in poor health during winter storms.

What is a tree preservation order (TPO)?
These orders are placed on individual and groups of trees by Shropshire Council. They make it illegal to carry out any work without obtaining prior consent. Trees protected in this way are usually mature specimens, which form an important part of an area's character. However, less prominent trees are sometimes protected, so you should be sure that a TPO does not exist before undertaking any work. There are exemptions under TPO legislation, such as if a tree is dead, dying or dangerous, but it is best to check with us. You may be liable to a large fine if you cannot prove that an exemption applied.
For more information, contact us via the details on this page and ask for the tree officer.
What is a conservation area?
A conservation area is a designation that covers historic built areas such as the centres of towns and villages and affects trees. This includes protection of medium and large trees (over 7cm in stem diameter measured at a height of 1.5m) within the conservation area. You will require permission from Shropshire Council before you can undertake any work to these trees.
A popular misconception concerning conservation areas and TPOs is that they apply only to specific species of tree. This is untrue; any species can be protected. Similarly specific species are not automatically granted protection.

How are hedgerows protected?
Hedgerows are protected under the 1997 Hedgerow Regulations. They make it a legal requirement to notify your district or borough council before removing a whole hedgerow or part of one. Hedgerows are considered worthy of protection due to the number of woody species they contain, or to associations with ancient monuments, historical parish or manor boundaries and other features.
