Acute oak decline is a tree disease, which has impacted Europe severely several times in over 2 centuries. Currently, there is a version of this disease being observed in the UK, which has been monitored and examined for 20 years. The targets of this disease are trees over 50 years old, meaning that veteran oaks are at particular risk.
The symptoms of acute oak decline include some of the following:
Several factors mostly determine the specifics of acute oak decline. The most important thing to remember is that the disease stresses out the trees. Things like waterlogging, pollution and sometimes drought are the environmental factors contributing to stressing the tree. Bacteria, fungi and insects can then further push an oak into decline.
It bears mention that oak decline occurs in stressed trees. There are certain processes taking place then, such as the tree being unable to supply enough water, its crown becoming thin and it loses a certain amount of leaves. In response to drought, a tree will develop dark patches on the bark. The stress factors combine and then lead to low amounts of energy within the tree to compensate for the issue at hand. In this condition, it may be ill-prepared for cold months and not be able to manage a pest infestation as effectively. For trees pushed into decline like that, death may take place in the following years.
Impact of acute oak decline
Oak decline has been monitored for over 250 years. Germany has had an issue with this disease since the 1990s. In the UK, the oak decline has mostly struck in Wales and the southern shores of England. As it is an atypical disease, the spread of it is much lower. The same cannot be said for its environmental impact, however, especially in regards to the environmental conditions become more unpredictable. As a result, other tree species experience the same decline.
The impact acute oak decline poses will increase, because environmental changes are ongoing still. Such a disease on trees will become more frequently surveyed, due to climate changes. Worse yet is the fact that the disease can cause the oak decline condition to be more severe.
Here is what can be done about the acute oak decline
Combating acute oak decline is not easy. One step in the right direction is to ensure more oaken trees are planted. More importantly, is planting them in an area that fosters their natural regenerative qualities. It is also important to do more research on the disease. Knowing what causes it and how it can be prevented and slow it down is very important.
Good tree surveying is of utmost importance when it comes to acute oak decline. Having experts explore the trees in a given area and take notes of their condition can make all the difference in the world. Changing matters isn’t always possible, but it is essential to assess the situation early on.

When it comes to dangers to UK trees, there are a lot of pests and diseases that qualify with the use of that word. It is important to monitor them and detect any issue early on so that it doesn’t lead to anything serious later on. Many pests and diseases can lead to very bad effects for trees if left rampant for too long.
One of the best ways to control pests and diseases is to detect them early on through tree surveys. When arborists do that, they have a much better chance to deal with the condition of the tree, regardless of what it may be. There are several major pests and diseases that tree surveys can reveal:
These diseases and pests are common enough that they need to be monitored and checked for through regular tree surveys, to minimise and prevent the damage from them.

The purpose of a tree survey is to provide essential information on the trees within a given area. Whether it is a private or public landscape, arborists can survey the land and gather data on the tree species, their age, condition, metrics and more. Also, the tree survey aims to provide information on various tree pests and diseases that may be present, as well as assess the risk of subsidence in the area. The survey outlines ways that a tree can be protected during any developments being made in the area, as well as provides information on tree preservation orders and more.
There are many different surveys that you can get for your property. The experts conduct each to a certain professional standard, based on your requirements. Here are some of the tree surveys you can have for your property:
As you know more about the different kinds of surveys, you are now better equipped to get experts and conduct the right one.
If you want to clear some land in the UK, which has trees, you will likely require a tree survey. This is something that professional arborists can carry out for you. If you are not sure what a tree survey is and how to get one, then the following guide is right for you.
What is a tree survey/tree report?
Tree surveys represent the process of gathering detailed data about trees present on a given property. These surveys aim to acquire more information about trees on both public and private landscapes. The reason why one would want to get a tree survey lies with the fact that owners of the land and representatives of the management team behind it have a legal duty to maintain the health and safety of trees, especially if the land is open to the public. Furthermore, to make the right decisions about the area owners need to have the expert level of information, which arborists can acquire during a tree survey. It is usually performed to the BS5837 standard. It presents a guideline for all of the data that needs to go into the survey, for it to be of any legal use.
What information do tree surveys collect?
The British Standard BS5837 accumulates all of the information necessary for tree surveys. Based on it, the experts provide data on:
All of this is mostly information for the experts to read and make recommendations based on. It is what makes the tree survey viable.
How to determine if you require a survey?
Carrying out a tree survey is required by law in many areas. One of the reasons for this is the species of trees in the area, many of which require protection. The Wildlife and Countryside Act of 1981 sets out the directives, which protect certain trees, i.e. stating they cannot be cut down. Another reason for tree surveys lies with developing the landscape. For those who want to build within the vicinity of trees, they will require a tree survey to determine whether the trees there are under a tree protection order and how to minimise the negative impact of development on them. Trees add great value to any property, and so any designer out there will first want to see a tree survey for recommendations on how to prevent any damage. Another important reason for tree surveys lies with detecting pests, diseases and structural damage, as well as the need to prune or otherwise assist the tree so that it doesn’t become a hazard.
Do you need a tree survey?
If you are close to finalising the plans for the development of your property, and you have a desire to add ancillary buildings or extensions, then a tree survey is something you need to get. If you need service lines or change of access to the property, you will also need a survey. It should include all of the trees present there, including any that are within influential distance. Needless to say, it has to be carried out by professional arborists, who know how to conduct the survey from A to Z and come up with the necessary data and recommendations.

An arboricultural survey is often used to identify and preserve trees within a given area. It provides important information to homeowners and estate managers with a plan on the trees within the area.
There are various reasons why you’d want to have a tree survey conducted. The most common of them are:
What Goes Into A Tree Survey?
There are a few important aspects of each survey:
One of the major purposes of a tree survey is that it has to be preemptive about certain issues that trees develop. To identify and assess these problems, experts conduct a survey, to have the information before a real problem escalates. And even though trees make for an important component of the landscape, when individual trees pose too serious of risk to property and people, they may need to be removed. Tree surveys outline this need or share the necessary steps to mitigating the risk and remedying the situation.
Sometimes tree surveys are necessary out of the need to comply with British duty of care, in addition to statutory requirements. Only licensed arborists conduct surveys, however, as they have the necessary tools and expertise for the job. This is also because tree surveys should adhere to various standards.
How long does it take to conduct a tree survey?
A quick survey is possible with a professional company. Their aim is usually to provide quick results since they know that homeowners and developers require them. Because of the tools and knowledge of the experts, a tree survey wouldn’t take long to execute. All that people need to do is find a company that works within the area and then consult with them on conducting a tree survey. They will be able to arrange things pretty quickly.

Tree surveys aim to provide a landowner with various data on the trees present there. Such a survey plays an important role in the development of the land and outlines steps to improve the condition of the trees on it. Every good landlord knows that trees boost the value of a property greatly and so need to be preserved. Furthermore, some trees are protected by law, like the Wildlife and Countryside act, which has to do with felling prohibition on protected trees.
Overall, it is clear that tree surveys are important enough so that you should never ignore them. But it is also important to understand how experts conduct them. There are a few types of surveys that are important: tree health surveys targeted surveys and pre-property development surveys. Each of them is specific:
Tree health surveys – inspect the health of all trees on the property, the presence of diseases and pests. Outlines possible cures and prevention methods.
Targeted surveys – these establish the damage and extent of a tree disease. Their goal is to predict further damage and prevent more issues.
Pre-property development survey – this is done to ensure the property complies with the British Standard BS5837: 2012, in the trees concerning the construction part.
So what are the phases of a tree survey? Following are each of them with a rundown of what they include.
Phase 1 – Pre-planning and setting parameters
Before the survey starts, experts plan out how they will conduct it. There are a few methods they can use.
Line transects – perhaps the most common way of conducting tree surveys. It involves walking a series of parallels and evenly-spaced lines. The experts then conduct an exam of all trees on the left and right of these lines.
Quarter-point transects – experts walk a line to the north, south, west and east starting from a diseased tree. That way they can estimate just how many trees are infected and how far the disease has spread.
Radius survey – when trees have great distances between them, this sort of survey is just right. Experts choose a radius and survey all of the tree species in that radius.
Complete survey – looks at all trees for signs of pests and diseases. It is the go-to method for small woodlands and parks.
Most tree surveys take place from the ground, although in some cases experts may need to climb them. This is because they have to examine the branches on top and the crowns. It is essential to pick the right time for a tree survey since not all diseases are active during certain seasons.
Phase 2 – Additional work
- For a survey to be considered viable, experts need to do the following:
- Note the position, species and condition of trees
- Check dimensions and crown spread
- Check leaf colour
- Inspect for deadwood and damaged branches
- Check for ivy growth, swellings, fungus, ark damage
- Check for exposed roots and root damage
- Check for cracks in the soil or uplifting of the concrete structures
- Experts will use tree tags to map the surveyed trees. When they are done, there will be an assessment of the value of the landscape.
Phase 3 – Impact assessment
During this phase, experts assess the impact of tree damage on the property. It contains such details, as what trees need to be removed, how to protect trees during the construction process and other recommendations to best preserve trees.
Tree surveys are an important part of tree maintenance and finding the right experts to conduct them is equally crucial.

When it comes to construction works, trees are often in the way. Many developers choose a site for new construction because of trees, as they add aesthetic value and boost the environment in many ways.
Unfortunately, this means that when the process of construction begins, trees in question are at risk. It takes planning and cares to preserve them on the building sites. Consulting with an arborist then becomes a necessity as does actively working with the builders to minimise the risk. There are certain things you can do to protect trees during construction:
What can you do in case of damage during construction?
Construction damage may affect the stability and structure of a tree. It is the job of an arborist to inspect potential risks. An inspection involves both visual examination and instruments that reveal the presence of decay. If there are risks identified, the arborist will recommend the removal of limbs and prune the tree. They may also install cables and braces that serve to increase structural support.
In case there is a need to treat the crown and trunk:
Now that you know better how to prevent construction damage, or address it after it has occurred, you can better protect trees.

While it is true that keeping trees healthy is always preferable, sometimes it may just not be possible to do so. The tree may have sustained severe damage after a storm, or there might be something else about it that you cannot fix. When a tree becomes a danger to people and property, it is taking it down that will become a priority. Bear in mind that cutting down a tree should always be a last resort because of the many implications this action has for wildlife and people.
And before you do it, you need to consider the rules that surround this act, as well as the alternatives.
What are your reasons for felling a tree?
There are many reasons why you may want to fell a tree. For starters, the reasons might be aesthetical, to minimise the impact of leaves/seeds and wildlife. Perhaps a more serious reason could be the fact that roots are causing subsidence in the nearby buildings, which is something to watch out for. In the case of the latter, even though you may have certain reservations, felling the tree could be the best option. If there is structural damage to the tree and it there is a potential it can fall, it might leave you no other choice.
What are the consequences of cutting down a tree?
There are many benefits to keeping trees around, which means that cutting down one is a negative thing. For starters, trees are home to various wildlife representatives. It is safe to say a lot of species depend entirely on trees for safety, finding food, shelter and reproduction. Since these species cannot find the resources they need elsewhere, they seek out trees in our gardens. Taking out their home doesn’t bode well for them.
Furthermore, trees provide oxygen and combat air pollution. They absorb the carbon emissions and serve a stabilising role for the soil with their roots. Spending more time near trees has also been proven to relax people and make them feel better. People value trees, which is a reason why having a few of them in your garden can boost the value of the property. Felling a tree means that you lose all of these benefits.
What are the alternatives?
If there is a serious problem, felling the tree may not be the only solution. Pruning and pollarding are two methods, which can save it. This can clear some of the hanging branches and reduce the weight of the tree in the setting. It is best to seek advice from a tree consultant/advisor, as they know how you can manage a problem tree. Sometimes doing some pruning is enough to preserve the tree in top shape. Make sure to contact an assured tree surgeon for the task. That way, you will know the task is done to a good standard. It is a good idea to contact the Arboricultural Association for the task.
Do you need permission to cut down a tree in your own garden?
If there is a Tree Preservation Order placed on the tree, then you will require permission from the local council if you wish to do anything with the tree. Trees under TPOs provide some amenity value, and you cannot just do whatever you want. First, you want to contact a tree officer who will be able to help you find out if there is such an order. If there isn’t, and the tree is not a Conversation Area, you don’t need permission.
Knowing more about the felling procedure of trees on your property will better help you determine the best course of action.
There are many surveys that a private or public landscape can use. Tree surveys are just one of the types, which have to do with providing the essential information on trees on that property and their condition. It is very important to gain this understanding of trees, to make more informed decisions when it comes to maintenance and construction.
There is a lot of information that tree surveys provide. Thanks to the established British Standard BS5837, arborists can determine the health of a tree and what steps should be taken to better the condition. Of course, there are many different types of services you can hire arborists for. Following is a quick guide on the matter:
1. Tree surveys for planning purposes
If you are about to submit your planning application and there are nearby trees in the location, you will do well to use qualified arboricultural consultants for a BS5837 survey. Thanks to this standard, the experts know the exact data that goes into the tree report, and they can use it to conduct the tree survey in accordance.
2. Tree surveys for determining tree condition
If you are responsible for a given number of trees on the property and you want to assess their condition, then a tree survey for safety/management purposes is in order. Contacting qualified arborists is always the first step. They will come to the area and closely examine all of the trees there for diseases and other defects. The report that follows will then provide information on how you can reduce the risks, or remove the danger altogether.
3. Tree surveys for buying a house
If you are buying or selling a house, there is the risk of subsidence to consider. This, as well as tree failure, are no small risks, and that is why you need a tree survey. It basically includes all of the trees within the influential distance of the property. In the report, experts will outline what steps you can take to minimise the risk and bring it down to an acceptable level, if not remove it completely.
4. Tree surveys for subsidence management
If there is already a case of subsidence, a tree survey is needed to determine the trees causing subsidence, or if trees are to blame for it in the first place. Arborists will conduct the tree survey on all trees within the potential influence. The goal of conducting a tree survey, in this case, is to outline ways to reduce the risks and manage the problem. It is important to rely on experts for the job, since tree subsidence in no small matter. Not only will they recommend a course of action for the current problem, but also outline how you can minimise future risks.
5. Tree preservation order
Tree preservation orders are usually created by Local Authorities, whether it be for individual trees, a group of trees or woodlands. The purposes of the TPO, in general, is to protect the tree from removal or improper pruning. These are all activities that result in a loss of amenities. Obtaining a Tree Preservation Order is usually done after a tree survey. To find out more on the matter, you best consult with an arboricultural agency.
6. Litigation
In the case where a tree has caused damage to a person or property, a tree survey is conducted. It is then presented as a report per law court standards.
Now that you know more about tree surveys, you can better ensure the right type is performed for you and your property.
Carrying out any work on some trees should always happen only after you have established their legal status. The reason for this is simple: the legislation of England puts some trees under protection, which means you cannot work on them unless you get all the proper authorisation.
Otherwise, you face the risk of prosecution and enforcement actions, like a criminal record and hefty fines. If you wish to find out more about tree preservation orders, planning conditions, felling licenses,
conservation areas and the restrictive covenants that protect a large part of the trees in the UK, read on:
Knowing all this now will definitely help you in regards to carrying out tree work in accordance with the legislation that applies.

If there are certain aspects of the work of arboricultural consultants that you are not sure of, it is time to clear them up. You should do that because you want to understand better the different aspects of the work that these experts do with your trees. It is important, as it guarantees the wellbeing of the trees and that there will not be major problems associated with them. Here are a few of those aspects and questions regarding arboriculture that you should learn more about:
There is no doubt that by now you know more about arboriculture. Knowing who to hire when you have a problem tree will prove quite valuable.
