Hazard assessment

As part of assisting clients in effectively discharging their legal duty of care in respect of tree ownership, we can provide tree inspection reports and surveys for individual trees through to larger quantities located in areas such as highway verges or parks. We also offer woodland management plans, veteran tree management strategies and decay detection and assessment using equipment such as the non-invasive PICUS Sonic Tomograph and the invasive Resistograph micro drill.

Arborist consulting services from Broadleaf Tree Services

Complementing our core business we are pleased to now be able to offer an arboricultural consultancy service to meet the requirements of clients who are responsible for individual trees such as home owners through to large collections of trees such as in business parks or schools. Our consulting arborists are qualified and experienced individuals with many years of experience in managing trees in a variety of locations.

Prior to any work being carried out, Broadleaf will assess the tree for any potential danger to the climber or arborist on site prior to ensure safety and reduce the risks of any accidents or potential damage to the tree.

 

This is also very useful to highlight any potential problems with the trees general health. From this we can provide you with some advice on if the problem can be rectified.

Types of hazard that may indicate a trees potential to fail.

•  Cracks

A crack is a deep split through the bark, extending into the wood of the tree. Cracks are extremely hazardous because they indicate that the tree is failing.

•  Weak Branch Unions

Weak branch unions can occur where branches are not strongly attached to the tree. They form when two or more similar-sized upright branches grow so closely together that bark grows between the branches, inside the union. This ingrown bark does not have the structural strength of wood, which results in a much weaker union.

•  Decay

Decaying trees can be prone to failure, but the presence of decay, by itself, does not indicate that the tree is hazardous. Advanced decay (wood that is soft, punky, or crumbly, or a cavity where the wood is missing) can create a serious hazard. Evidence of fungal activity, including mushrooms, conks, and brackets growing on root flares, stems, or branches, are indicators of advanced decay.

•  Cankers

A canker is a localized area on the stem or branch of a tree where the bark is sunken or missing. Cankers are caused by wounding or disease. The presence of a canker increases the chance of the stem breaking near the canker. A tree with a canker that encompasses more than half of the tree’s circumference may be hazardous even if the exposed wood appears sound.

•  Root Problems

Trees with root problems may fall without warning. Soil mounding, twig dieback, dead wood in the crown, and leaves that are off-colour or smaller than normal are symptoms often associated with root problems.

•  Poor Tree Architecture

Poor architecture is a growth pattern that indicates weakness or structural imbalance. Trees with strange shapes are interesting to look at, but may be structurally defective. Poor architecture often arises after many years of damage from storms, unusual growing conditions, improper pruning or topping, or other damage. Any abnormalities should be examined by an arborist knowledgeable with that species of tree.

•  Uneven Crown Growth

Uneven crown growth can come as a result of a badly pruned a tree, or as a result of storm damage. A tree with uneven crown growth can become unstable and prone to fail.
