Everything You Need to Know About Tree Surveys
Why Do I Need a Tree Survey?
If you have been asked for a tree survey, there are a number of reasons why you may need a tree expert to provide one. Your local authority may demand that you arrange for an arboricultural consultancy to undertake a tree inspection of your site and produce high quality tree reports as a method of supporting your planning application if they are concerned that your proposed development may impact trees or vegetation near or on your development site.
In some cases, your lender or bank may even ask for a tree survey as part of their criteria for mortgage approval, or your insurer may need a tree survey to assess the condition and safety of your trees. For instance, health and safety tree assessments not only evaluate the potential impact on trees and individuals, but also the impact a tree could have on the hard surfaces and features situated within the boundaries of the chosen plot of land. You may also need a tree survey to apply for works to trees protected by Tree Preservation Orders (TPOs) or located in conservation areas.
Whatever you need a tree survey for, our team of friendly, expert tree consultants hold many years of experience working with both private or commercial clients and have supported numerous landscape designers, planning consultants, project managers, land owners, property owners, tree owners and other professionals in different types of land development project. Including design, demolition and construction, our knowledgeable team has extensive experience working on a variety of projects and carrying out tree inspections on development sites to support applications for planning consent and the quality of the local environment.
Our team has the full range of skills needed to conduct tree surveys on any new building project, including a comprehensive understanding of the state-of-the-art equipment such as tree motion sensors, and further information about the tree surveying process, such as the scientific name and common name given to relevant elements. With this advanced knowledge, each tree surveyor can take physical measurements of tree diameter, height and root protection areas, gauge whether a site should have a tree removed as a result of fungal decay on single trees present on the site, and eliminate breaches of personal safety that could have otherwise caused damage or harm.
Operating throughout the year, in bad weather and on hazardous sites with evidence of tree failure, we are able to provide you with a free quote based on your project and the only variable regarding the number of trees present, issue a tree surveyor to your site and ensure that all trees inspected are assessed correctly to guarantee assurance over health and safety, offer a wide range of accurate information to appease the planning authority, and move your development through planning.
What is a BS5837 Tree Survey?
Your local council has policies that protect trees in your area. At any point that you are spending time developing existing buildings or on land proximate to trees, a British standard BS5837 tree survey is generally required by your local authority’s planning office before they will consider your development proposal as a form of validation requirement. Along with other components such as tree constraints highlighted within plan drawings, the requirement of a tree survey is because – whether you wish to construct a small house extension or a 500-unit commercial development – your council could deem that it is capable of negatively affecting the surrounding trees.
Usually, all trees over a 7.5cm diameter need to be included in the BS5837 tree survey, though they don’t all have the potential to constrain your development, including off-site trees and other vegetation within ten metres of your site boundary. The BS5837 survey must include the species of tree and its orientation, as well as dimensional and root protection area data. Tree surveys include notes about the structural and physiological condition of the trees and other relevant features on the site such as shrub areas, hedges and regenerating woodland.
In your BS5837 assessment, the trees’ positions are of particular importance and should be marked up following a topographical survey (otherwise known as a contour survey, detail survey, land survey or terrain survey) or OS tile. This will ordinarily show all relevant site features, including existing buildings, roads, street lighting, drains, walls, fences and any other components involved in what is being proposed that could act as possible constraints to tree retention and root development.
Alongside the BS5837 assessment, there are other forms of tree survey that suit a variety of purposes, including an Arboricultural Impact Assessment (AIA), arboricultural method statement, health & safety tree survey, mortgage tree report, and arboricultural supervision and site monitoring. Each of these inspections are designed to uncover detailed information about protected trees on the corresponding development site and meet certain goals. As experts on tree surveys, we can offer all of these services.
What is a Tree Report?
For developments to pass most planning applications, the corresponding local authorities require information provided on how each tree will be dealt with and how the development can go ahead without harming the existing state of biodiversity despite the presence of trees. In order to ensure a record of all of the useful information with effective tree management recommendations included, the professional arboriculturist will develop a tree report.
Tree reports act as extremely important tree protection plans and method statements for making informed decisions along the planning process. Within a tree survey report, an extensive range of considerations are included, such as drawings of the site with every tree outlined, gradings of every tree on the site, and potential safety aspects of existing trees. Once a visual tree assessment has been carried out, arboricultural consultants will create high-quality tree reports immediately after. Completed tree reports will then be sent to the local council and passed on to the local authority as part of the application for planning permission.
What is a Tree Preservation Order?
Tree Preservation Order (TPO) protection is a form of tree protection plan afforded to trees under the Town and Country Planning Act 1990. It is especially important to have a tree survey undertaken prior to disrupting a tree protected by a Tree Preservation Order as it would require the special consent of your local council’s planning office.
Individual trees are specifically placed under a TPO, and once a request to carry out a development that could impact a tree under a TPO has been made, it can take up to eight weeks for the council to provide a response. Impact on a tree could involve any form of direct interference such as cutting down, lopping, uprooting, or wilful damage and destruction. However, there are exceptions, such as if the tree survey suggests that the tree is dead, dying or dangerous to individual safety, or if other criteria means that you no longer need a granted planning application from the planning department of the local council.
What is a Conservation Area?
Alongside Tree Preservation Orders (TPOs), a conservation area is another consideration that can post troublesome obstacles during a land development on a site that houses protected trees. Introduced in the Planning (Listed Buildings and Conservation Areas) Act 1990, the concept of a conservation area enables local authorities to preserve certain sections of land and all trees therein based on special architectural or historical interest.
As with Tree Preservation Orders, consent from the corresponding local planning authority is needed before any work on a conservation area that could disturb trees is carried out. Likewise, only a qualified and insured tree survey consultant can make suitable judgements when it comes to individual trees under a TPO and trees situated in a conservation area. Even if you are unsure if a tree is affected by TPOs or conservation areas, it would be advisable to seek professional advice from a qualified arboriculturist with an acceptable level of knowledge and experience.
What is the Tree Survey Process?
Although there are multiple forms of tree condition survey, the BS5837 assessment is the most common form of tree survey and sees an arboricultural consultant following the same process to establish tree constraints, retrieve detailed information, reduce risks and make informed decisions.
After asking a few questions about the project and gathering information about how and where it will be carried out, the surveyor will arrange a visit to the site at a suitable time that fits in with the schedule of the developer in charge of the project. It would always be advisable to book a tree survey as early as possible to guarantee a desirable slot, and once a tree condition survey is conducted, the completed tree report should be distributed within a few short days.
In the preliminary stage, the arboricultural consultant may conduct a desk study to collect vital information. For instance, they may find that an existing tree protection plan is in place, the site may have previously had an arboricultural method statement, or someone outside of the site could be a tree owner or have jurisdiction or a duty of care over single trees on the site.
Arboricultural surveyors will assess every tree on the site, using a grading system to determine the physiological and structural condition and value of each tree before establishing whether retaining, relocating or destroying is the most suitable course of action for each individual tree. Naturally, the top priority would have as many retained trees on the site as possible following a tree inspection, but if they are low in quality, not protected by a TPO, expected to have a short life expectancy or likely to obstruct the development, moving them elsewhere or destroying them may be the only option.
The arboricultural surveyor who conducted the assessment will then complete the tree surveying process by creating the tree survey report. Not only does a tree assessment report act as a detailed overview of tree inspections, an explanation of how tree surveys are carried out and an opportunity for the arboriculturist to detail how they approach the process with an eye on an acceptable level of tree care and the environment, it also offers effective next steps for enabling the development to progress despite the presence of trees.
Through cross-referencing trees on the site alongside the development and site plan, creating a CAD drawing that outlines every tree on the site, and providing information on all other relevant factors in the form of different types of written or pictured evidence, the arboricultural consultancy can provide a detailed tree report. With every component required to gain planning consent, the report will be passed on to the relevant local authority to support the planning application.
Tree Surveys for Land Developments
While a tree survey may not exactly be one of the primary components you would expect to incorporate into your planning project, in the majority of circumstances, tree surveys are undertaken as part of land developments where trees are present.
At this point, an arboriculturist will examine all tree stock on the plot of land, gauge the impact of trees in relation to design, demolition or construction work, and indicate to the local planning authority that all trees have been correctly analysed and a suitable course of action for each tree has been determined. Featuring all of the evidence and next steps in the tree report, the process of passing a planning condition should be quick, simple and seamless.
Other Reasons for Scheduling Tree Inspections
Alternatively, however, a tree survey can occupy other needs outside of property or land development projects. For example, mortgage lenders often ask for a tree survey, though even when they do not ask for them as planning conditions of the mortgage, it is often an excellent way to get a sense of what trees are on or adjacent to the property.
Primarily for overall health and safety purposes, a tree survey on a mortgage application will establish if present trees could be a danger to people. In most circumstances, even great trees that are tall or wide will cause no danger whatsoever. That said, it would be advisable to have a tree survey undertaken by an insured and qualified professional tree surveyor to avoid ending up buying a house next to a huge, mature tree that is rotten and needs to be felled at your expense.
Likewise, tree surveys for condition and safety reasons are also undertaken to provide peace of mind for homeowners around the country, as well as discharging their obligations under the Occupiers’ Liability Act 1957. It is, however, a common misconception that the Wildlife and Countryside Act 1981 affects tree problems. In fact, it solely focuses on protected species and animal habitats across the country.
