Trees are an essential part of our environment and play a vital role in maintaining the ecological balance. They provide oxygen, absorb carbon dioxide, prevent soil erosion, and offer habitats for wildlife. They also enhance the aesthetic value of our surroundings and offer shade and cooling effects, which are beneficial to our health.
As much as we appreciate the beauty and benefits of trees, they can pose a risk to human life and property if not well-managed. Therefore, it’s important to regularly conduct tree surveys to ensure they are healthy, safe, and properly maintained. Tree surveys can also help to identify potential risks and recommend appropriate measures to prevent incidents.
What is a tree survey?
A tree survey is a systematic inspection of trees to determine their condition, health, and risk potential. It involves a detailed examination of trees to identify any issues, such as disease, structural damage, pests, or any other factor that may impact the safety or health of the tree.
Tree surveys involve a visual assessment of trees, often from the ground, and sometimes require the use of equipment, such as aerial platforms, to inspect the crown of trees. The surveyor will examine the tree’s structure, including the trunk, branches, and roots, to identify any signs of damage or disease. They will also check the surrounding area to determine if any hazards are present that may affect the tree’s health or safety.
What is the role of tree surveyors?
Tree surveyors are trained professionals who conduct tree surveys. They have the expertise to identify potential risks and recommend appropriate measures to prevent incidents. They also have a good understanding of the various species of trees and their different growth habits, which helps in the evaluation of the tree’s health and structural integrity.
The importance of the BS5837 tree survey standard
The British Standard BS5837 sets out guidelines for conducting tree surveys and managing trees in relation to construction projects. The standard provides a systematic approach to assessing the impact of development on trees and identifying measures to protect them.
Complying with the BS5837 tree survey standard is essential for ensuring that trees are properly protected during construction activities. The standard helps to ensure that the potential impact of development on trees is considered, and appropriate measures are taken to protect them. By complying with the standard, property owners can avoid legal issues and ensure that trees remain healthy and safe.
How does the BS5837 standard ensure the safety of trees?
The BS5837 standard requires the identification of the critical root zone (CRZ) for each tree. The CRZ is the area around a tree where soil compaction, excavation, and root damage can have a significant impact on the tree’s health and stability. By identifying the CRZ, measures can be taken to prevent damage to the tree’s roots during construction activities, which helps to ensure its continued health and stability.
What potential risks are posed by trees?
Trees can pose various risks, including falling branches, tree collapse, root damage, and fire hazards. Falling branches can cause injuries, and in extreme cases, even death. Tree collapse and root damage can cause property damage, while fire hazards can lead to the destruction of homes and other structures.
Identifying potential risks posed by trees is critical to ensuring the safety of people and property in the surrounding area. Through a tree survey, potential hazards can be identified, and appropriate measures taken to mitigate the risks, including tree removal or pruning.
A tree survey can identify potential hazards, such as weak branch unions, decay in the trunk or roots, and damage caused by pests or disease. The survey can also identify trees that may be too close to structures, power lines, or roads, and those that are leaning or otherwise unstable. Identifying these potential risks can help to prevent incidents and keep people and property safe.
What diseases and pests can a tree be susceptible to?
Trees, like all living organisms, can be susceptible to various diseases and pests. These can range from small pests like aphids and mites to large diseases like Dutch Elm Disease and Oak Wilt. These diseases and pests can affect the tree’s overall health, reduce its lifespan, and increase the risk of incidents, such as falling branches or tree collapse.
Common tree diseases
Identifying the health and condition of trees is important for maintaining their well-being and preventing incidents. Through a tree survey, potential diseases can be identified and addressed, such as:
Oak wilt
Oak wilt is a destructive disease of oak trees caused by the fungus Ceratocystis fagacearum also known as Bretziella fagacearum.
Dutch elm disease
Dutch elm disease causes the wilting and death of the tree. It is caused by the fungus Ophiostoma novo-ulmi, which invades and blocks the water-conducting systems of trees.
Common tree pests
Emerald ash borer
Emerald ash borer is an exotic beetle pest that affects ash trees. It causes significant damage to the trees, including dieback and death.
Gypsy moth
The gypsy moth caterpillars affect the leaves of a wide range of broadleaved trees and shrubs, but oak trees are particularly affected.
Signs of stress
Leaf discoloration
The discoloration of the leaves of plants can have many different causes. In some cases it is indicative of adverse factors such as nutrient deficiencies, pests, diseases or cultural problems.
Premature leaf drop
Premature leaf drop is usually due to dry weather. Trees are damaged by leaf desiccation, slowing of photosynthesis, and slowing of growth. Leaves wilt, turn off-colour, and drop.
Bark damage
Bark damage can mean the complete or nearly complete loss of bark from around the circumference of a tree’s trunk. This disrupts the movement of water and nutrients between the roots and the top growth.
Appropriate measures can be taken, including pruning, fertilisation, and treatments, to help ensure the tree’s continued health and reduce the risk of incidents.
How much does a tree survey cost?
The cost of a tree survey can vary depending on several factors, such as the number of trees, their size, and their location. Typically, the cost ranges from a few hundred to a few thousand pounds.
While the cost of a tree survey may seem high, it is important to consider the potential cost of a tree-related incident, which can be much higher. For example, if a tree falls on a house, the repair costs can be tens of thousands of dollars, and if someone is injured, the cost can be much higher. Investing in a tree survey is a proactive step to prevent incidents and reduce the potential for significant costs.
What is the cost of not getting a tree checked?
The cost of a tree-related incident can include property damage, medical bills, and legal fees. For example, a tree falling on a car can result in the cost of repairing or replacing the vehicle. A tree falling on a house can cause damage to the roof, walls, and foundation, resulting in significant repair costs. If someone is injured or killed, the costs can include medical bills, lost wages, and potential legal fees.
Tree surveys are essential for maintaining the health and safety of trees, identifying potential risks, and preventing incidents.Property owners should consider investing in a tree survey to ensure the safety and health of their trees, prevent incidents, and reduce potential costs. Tree surveys are an important aspect of tree management and help to ensure the continued health and safety of trees. By identifying potential risks, addressing health issues, and complying with industry standards, property owners can protect their trees and reduce the potential for incidents and costs.
