    Arboricultural Method Statement — Quick Answer

    What is an Arboricultural Method Statement?

    An Arboricultural Method Statement (AMS) explains how demolition or construction work will be carried out where retained trees need protection. It turns the approved arboricultural strategy into practical site instructions for operations such as access, excavation, services, surfacing, fencing and supervised work.

    The construction-stage tree document

    What is an Arboricultural Method Statement?

    An Arboricultural Method Statement, often shortened to AMS, is a project-specific document explaining how relevant demolition and construction operations will be carried out where retained trees need to be protected.

    Planning to site

    Turns commitments into instructions

    The statement can convert approved arboricultural principles into a clear sequence that contractors can understand and implement.

    Sensitive operations

    Controls work near retained trees

    Fencing, ground protection, demolition, excavation, services, surfacing, access, storage and supervised works can all be addressed where relevant.

    Planning conditions

    Can form part of condition information

    Where permission requires an AMS or related tree-protection information, the document can form part of the material submitted to address that condition.

    When is an Arboricultural Method Statement required?

    When is an Arboricultural Method Statement required?

    An AMS may be requested with an application, as part of a detailed BS5837 package, or after permission through a planning condition. The trigger depends on the retained trees, site constraints, design and exact wording issued for the project.

    Pre-commencement

    Tree-protection condition

    A decision notice may require detailed protection or methodology to be approved before the relevant works begin.

    Design conflict

    Work close to RPAs

    Excavation, surfacing, foundations or access close to retained trees may need a clearly described and coordinated method.

    Services

    Drainage or utilities near trees

    Routes and installation methods may need arboricultural coordination where root disturbance is a material concern.

    Construction

    Supervised sensitive operations

    Some works may require consultant attendance, records or hold points where arboricultural judgement is needed on site.

    An AMS does not itself authorise work to start.

    If permission contains a pre-commencement condition requiring written approval, that condition must be dealt with through the appropriate planning route before works governed by it commence.

    Where the AMS sits in the BS5837 process

    Survey → AIA → TPP → AMS → supervision.

    These documents do different jobs. The correct combination depends on the project and planning stage, so an AMS should not simply duplicate an earlier report.

    01 · Baseline

    BS5837 Tree Survey

    Records the relevant trees and the arboricultural context of the site.

    03 · Protection

    Tree Protection Plan

    Shows where barriers, exclusion areas and other protection measures are located.

    04 · Method

    Arboricultural Method Statement

    Explains how relevant operations are to be undertaken near retained trees.

    05 · Site stage

    Arboricultural Supervision

    Provides consultant attendance or records where required by the agreed strategy.

    What a professional AMS can include

    What does an Arboricultural Method Statement include?

    Not every project needs every item below. The AMS should be proportionate and site-specific, covering the operations that genuinely interact with retained trees and the planning requirements.

    Protection setup

    Fencing & exclusion areas

    Barrier locations, sequencing, controlled access and any restrictions on when protection can be altered.

    Ground protection

    Temporary access & working areas

    Measures for protecting soil and rooting areas where pedestrian, plant or vehicle movement is proposed.

    Demolition

    Removal of existing structures

    Controlled demolition, slab removal, foundation removal and access where retained trees are close to the work.

    Excavation

    Digging near retained roots

    Hand excavation, supervised excavation, root discovery procedures and limits on mechanical excavation where relevant.

    Services

    Drainage & utilities

    Preferred routes, trenching controls and coordination with project designers where services pass close to retained trees.

    Hard landscape

    Surfacing & no-dig approaches

    Arboricultural principles for reduced-dig or no-dig surfacing where such an approach is part of the accepted design.

    Foundations

    Construction close to trees

    Relevant arboricultural controls around foundations, piles or other construction elements where the approved design needs them.

    Site logistics

    Storage, compounds & plant

    Restrictions on materials, washout, plant movement, temporary compounds and activities that could damage rooting areas.

    Supervision

    Hold points & records

    Operations requiring consultant attendance, notification, photographs or records before the next work stage proceeds.

    Construction Exclusion Zones & Root Protection Areas

    Two related ideas that should not be treated as identical.

    The RPA is an arboricultural planning tool. The Construction Exclusion Zone is the practical area intended to be protected from unauthorised construction activity. A project-specific AMS should explain how the approved strategy is implemented on the ground.

    Root Protection Area (RPA)

    The RPA helps inform the minimum rooting area that should be considered when designing and planning works around retained trees. Site-specific conditions, actual root distribution and the approved development context remain important.

    • Used during design and impact assessment
    • Usually shown on arboricultural drawings
    • Helps identify where construction conflicts may arise
    • Does not mean every square metre contains the same roots

    Construction Exclusion Zone (CEZ)

    The CEZ is the area to be protected from unauthorised activity during works. It may be defined by barriers, ground protection, controlled access or other measures shown in the approved strategy.

    • Relevant to contractors and site management
    • Should be clear before enabling works begin
    • Storage and plant movement may be restricted
    • Changes should follow the approved planning route
    Construction methods near retained trees

    Typical operations that may need a site-specific method.

    The correct method depends on the tree, site, approved design and engineering requirements. An AMS should coordinate arboricultural controls with the relevant design disciplines rather than pretending to replace them.

    OperationArboricultural concernWhat the AMS may need to defineOther coordination
    DemolitionStructures close to treesRoot, stem or crown damage during removal.Sequence, access, machinery position and supervised limits.Demolition contractor and structural requirements.
    ExcavationWork in or near RPAsRoot severance and soil disturbance.Hand-dig or controlled excavation method, root discovery protocol and supervision.Engineer, contractor and approved design.

    Planning-condition wording matters

    The wording tells you what must happen and when.

    The safest starting point is the exact decision notice or planning request. Small differences in wording can change whether information is required before commencement, before demolition, before a particular operation or as part of a wider discharge package.

    Pre-commencement

    Approval may be required before relevant work starts

    The AMS may form part of the information that needs written approval before works governed by the condition commence.

    Protection setup

    Barriers may need to be installed before enabling works

    The condition may specify timing, inspection, photographs or approval of tree-protection measures before demolition or construction.

    Specific operations

    Certain works may need their own method

    Excavation, surfacing, services, foundations or access can require more detail where they interact with retained trees.

    Supervision

    Consultant attendance may be tied to defined stages

    The condition or approved AMS may identify hold points where arboricultural supervision or records are required.

    Variations

    Site changes can affect the approved tree strategy

    If the contractor wants to move fencing, reroute services or change a method, check whether arboricultural or planning approval is required before implementation.

    AMS for planning-condition discharge

    Turn the condition wording into a deliverable plan.

    Where an Arboricultural Method Statement is required by condition, the submission should respond to the wording actually imposed. It may also need a Tree Protection Plan, supervision details or other supporting information.

    Step 1

    Read the condition

    Identify the trigger, documents requested, approval mechanism and any specific construction or supervision requirements.

    Step 2

    Check the approved drawings

    Make sure the AMS and TPP relate to the current approved scheme rather than a superseded design revision.

    Step 3

    Prepare the site-specific information

    Set out the protection, sequence, methods and supervision relevant to the actual construction operations.

    Step 4

    Cross-reference the drawings

    The written method and Tree Protection Plan should use consistent revisions, labels and protection terminology.

    Step 5

    Submit through the correct route

    The project team or planning agent can submit the required information in accordance with the permission and authority process.

    Step 6

    Brief the site team after approval

    The approved documents should then be issued to the contractor and incorporated into construction planning.

    Roles & responsibilities

    The AMS works best when every discipline stays in its lane.

    Arboricultural methodology should coordinate with the project team. It does not replace engineering, architectural, drainage, demolition or contractor design responsibilities.

    Arboricultural consultant

    Tree protection & methodology

    Defines arboricultural constraints, site-specific protection principles, sensitive-operation requirements and supervision where relevant.

    Architect / designer

    Design coordination

    Coordinates the approved development layout and revisions with the arboricultural information and wider design team.

    Engineer / specialist designer

    Technical design

    Provides the structural, drainage, pavement, utility or geotechnical design required for the relevant construction element.

    Contractor / site manager

    Implementation

    Briefs the site team, follows the approved sequence and protection measures, and raises proposed variations before they are implemented.

    Arboricultural supervision & monitoring

    Some operations need more than written instructions.

    Supervision can be useful where the planning condition, approved AMS or sensitive operation requires arboricultural judgement on site. The exact attendance should be proportionate to the risk and agreed scope.

    Before works

    Protection inspection

    Check that fencing, exclusion areas or ground protection are in the intended position before the relevant construction stage begins.

    During works

    Sensitive excavation

    Attend operations where roots may be encountered and the approved method requires arboricultural input or a defined hold point.

    Records

    Site notes & evidence

    Photographs or concise supervision records can document what was observed and the advice provided during the agreed attendance.

    VIEW ARBORICULTURAL SUPERVISION →

    TPOs, conservation areas & retained trees

    Construction methodology does not replace tree-protection controls.

    Tree Preservation Orders, conservation-area controls and planning conditions are separate considerations. An AMS should work within the approved planning position rather than being treated as permission for unrelated tree work.

    Protected trees

    Where retained trees are protected, proposed work to the trees themselves may require a separate application, notice or other planning route depending on the circumstances. The AMS is concerned with implementing the development methodology around those trees.

    Approved development

    If development has already been permitted, follow the decision notice, approved plans and any arboricultural conditions. Proposed variations should be checked before site teams depart from the approved strategy.

    Common AMS mistakes

    Avoid the gaps that create planning or site friction.

    A method statement should be usable by the contractor and consistent with the planning permission. Generic wording and outdated drawings are common reasons a technically plausible document becomes difficult to implement.

    01

    Generic template wording

    A method that does not refer to the actual layout, operations and tree constraints gives the site team little useful direction.

    02

    Outdated drawings

    Protection and methodology based on superseded plans can conflict with the approved construction layout.

    03

    No contractor handover

    A strong PDF is ineffective if demolition, groundwork and site-management teams never see or understand it.

    04

    Unclear supervision points

    If sensitive work needs consultant attendance, the programme should identify when notice is required and what activity is being observed.

    05

    Ignoring drainage or services

    Late service routes can introduce new excavation within tree-sensitive areas even when the building layout itself is acceptable.

    06

    Uncontrolled site changes

    Moving fencing, access or working methods without checking the arboricultural and planning implications can undermine the approved strategy.

    How the AMS service works

    How does the AMS process work?

    01

    Send the condition & drawings

    Use the form above or email the decision notice, approved plans, existing tree information and contractor questions.

    02

    Review the actual requirement

    The condition, design, existing BS5837 information and likely construction interactions are reviewed before the scope is confirmed.

    03

    Prepare the method & drawings

    The agreed AMS and any related Tree Protection Plan or supporting information are prepared around the actual project.

    04

    Support implementation

    Where required, the work can continue into arboricultural supervision, site records or advice on proposed construction-stage variations.

    Real construction-stage scenarios

    The right method depends on what is actually being built.

    The same AMS template should not be applied to every site. These examples show why the methodology needs to follow the actual conflict and construction sequence.

    Scenario 1

    Driveway or parking within an RPA

    The method may need to address excavation limits, ground protection, surface build-up, edge restraint, levels and the order in which protection is removed or replaced.

    Scenario 2

    Drainage route close to retained trees

    Tree-sensitive sections may require route changes, controlled excavation, supervised work or coordination with the drainage designer before the trench is opened.

    Scenario 3

    Demolition beside a retained tree

    Plant location, pull direction, slab removal and access can all matter where demolition activity sits close to the stem or rooting area.

    Scenario 4

    Foundation or pile construction near trees

    The arboricultural method should coordinate with the engineer’s design and define the tree-protection sequence, excavation controls and any supervision required by the approved strategy.

    Contractor handover

    The AMS should survive the site handover.

    A technically correct report can still fail operationally if the people carrying out the works do not know which document is current, where the protection sits or which activities need arboricultural attendance.

    Issue the latest AMS and TPP

    Superseded revisions should be removed from circulation so contractors are not following conflicting protection layouts.

    Brief the site manager before enabling works

    Tree restrictions should be understood before demolition, excavators, deliveries and temporary compounds arrive.

    Mark supervised operations in the programme

    Hold points should be planned rather than discovered on the morning the work is due to start.

    Include relevant subcontractors

    Groundworkers, drainage teams, landscapers, utility installers and demolition crews can all affect retained trees.

    Control variations

    Check the arboricultural and planning implications before moving fencing, rerouting services or changing a construction method.

    Watch the AMS briefing

    What an Arboricultural Method Statement actually does on site.

    A short Arbor Cultural briefing on turning planning requirements into construction-stage instructions for protecting retained trees around demolition, access, excavation, services and building work.

    Useful starting point

    Send the exact planning-condition wording and the latest approved drawings. That makes it easier to determine whether the project needs an AMS alone or a wider package including a TPP or supervision.

    Arboricultural Method Statement cost

    How much does an Arboricultural Method Statement cost?

    A simple AMS using reliable existing tree information is different from a constrained construction site needing revised protection drawings, service coordination, complex methodology and multiple supervised operations.

    What affects the fee?

    Main scope factors

    • Complexity of the planning condition
    • Whether reliable BS5837 information already exists
    • Whether a Tree Protection Plan needs preparing or revising
    • Number and complexity of construction interactions
    • Quality and revision status of available drawings
    • Need for site visit or updated survey information
    • Whether supervision or construction-stage records are required
    What should I send?

    You do not need a perfect information pack

    Start with what you already have. The condition and approved drawings are usually more useful than trying to describe the requirement from memory.

    Arboricultural Method Statement FAQs

    Technical questions, plain answers.

    If you have a planning condition, decision notice, approved drawing or contractor query, send the wording exactly as issued. You do not need to translate it into arboricultural terminology first.

    What is an Arboricultural Method Statement?

    An AMS is a site-specific document describing how relevant demolition and construction operations will be carried out while protecting retained trees and implementing the agreed arboricultural strategy.

    When is an Arboricultural Method Statement required?

    It may be requested with a planning application or through a planning condition, particularly where development is close to retained trees and the planning authority needs detail on protection, access, excavation, surfacing, services, supervision or other construction operations.

    Is an AMS the same as a Tree Protection Plan?

    No. The Tree Protection Plan is primarily the spatial drawing showing protection and controlled working areas. The AMS explains how relevant operations are to be undertaken. They are often used together.

    Can an AMS be used to discharge a planning condition?

    Yes, where an AMS is among the information required by the condition. The submission must still respond to the exact condition wording and may also need a TPP, supervision details or other information.

    Can I start work as soon as the AMS is written?

    Not necessarily. If the permission contains a pre-commencement condition requiring written approval from the Local Planning Authority, the relevant condition must be dealt with in accordance with the permission before works governed by that condition commence.

    Does an AMS need a new tree survey?

    Not always. If reliable, sufficiently current BS5837 information and approved planning documents already exist, they may provide the necessary baseline. If site conditions, trees or proposals have materially changed, further survey or updated information may be appropriate.

    What is a Construction Exclusion Zone?

    It is the area intended to be protected from unauthorised construction activity around retained trees. The approved strategy may use protective fencing, ground protection or other controls to define and manage it.

    Can construction take place inside a Root Protection Area?

    Sometimes a planning-approved design requires controlled operations within or close to an RPA. Whether that is acceptable depends on the tree, site, extent of encroachment, proposed method and planning context. The AMS can set out the site-specific method where such work has been accepted in principle.

    Does an AMS include no-dig construction?

    It can. Where reduced-dig or no-dig surfacing is appropriate, the AMS can explain the arboricultural principles, sequence and protection requirements. Engineering design should still be provided by the relevant designer where needed.

    What about drainage and underground services?

    Service routes can be a major source of root disturbance. The AMS may identify preferred routes and controlled methods, but drainage and utility design should be coordinated with the relevant project professionals.

    When is arboricultural supervision needed?

    Supervision may be specified by the planning condition, approved AMS or TPP, or recommended for operations where arboricultural judgement is needed on site. Typical examples can include sensitive excavation, barrier changes or work close to important roots.

    Can you update an existing AMS if the design changes?

    Yes, but the planning implications of the change need to be understood first. A materially changed design may require updated arboricultural assessment, revised protection information or further approval rather than simply editing the wording of the original AMS.

    How long does an AMS take?

    Timescale depends on the condition, available drawings, whether an existing survey/TPP can be relied on, site complexity and whether further site work is needed. Your fixed-fee proposal can confirm the expected programme for the specific instruction.

    Who should read the Arboricultural Method Statement on site?

    At minimum, the principal contractor or site manager should understand the tree-protection requirements relevant to the works. Sensitive requirements should also be communicated to affected subcontractors such as demolition, groundwork, drainage, utility and landscaping teams.

    Should the AMS include the Tree Protection Plan drawing?

    They are often issued together because the TPP shows where protection and controlled areas are located while the AMS explains the method. Whether they are separate documents or combined within one report is less important than clear cross-referencing and consistent revision control.

    Can protective fencing be moved during construction?

    Only in accordance with the approved planning/tree-protection strategy. If the AMS or condition requires arboricultural or Local Planning Authority agreement before a change, that agreement should be obtained through the appropriate route before the barrier is moved.

    What happens if roots are discovered during supervised excavation?

    The response depends on root size, location, tree significance, the approved method and the purpose of the excavation. This is exactly why some operations are identified as arboricultural hold points rather than left to an unplanned decision by the groundworker.

    Can the AMS specify hand excavation?

    Yes, where hand excavation is appropriate to the operation and planning strategy. However, the method should be proportionate and site-specific; “hand dig everything inside the RPA” is not automatically the correct response to every project.

    Can an AMS deal with pile foundations?

    It can address the arboricultural constraints, access, excavation limits and protection requirements associated with the foundation strategy. The structural design and calculations for piled foundations remain the responsibility of the appropriate engineer.

    Can an AMS cover cellular confinement or no-dig surfacing?

    Yes. The arboricultural document can set out the principles, sequencing and tree-protection requirements for a reduced-dig or no-dig surface. Loading, pavement design and detailed engineering may still require specialist design input.

    What should happen if the contractor wants to change the drainage route?

    The arboricultural implications should be checked before the new route is excavated. A route that moves into an RPA may require an alternative method, updated drawing, supervision or further planning approval depending on the approved documents and condition wording.

    Are tree-protection signs useful?

    They can be. Signs attached to protective barriers can help communicate that an area is a protected tree zone and should not be entered, altered or used for storage without authorisation. They are a communication aid rather than a substitute for correctly installed physical protection.

    Does the AMS need to address material storage and cement washout?

    Where relevant, yes. Tree protection is not limited to root severance. Storage, soil compaction, contamination, washout, fires and changes in site use can all be relevant to retained-tree protection.

    Can you review an AMS prepared by another consultant?

    Potentially, yes. If a project has changed hands or the council has raised comments, send the existing AMS, Tree Protection Plan, decision notice and latest drawings so the required review can be scoped properly.

    Can an AMS support a retrospective planning problem?

    Sometimes arboricultural evidence can help explain a current site situation, but an AMS cannot retrospectively undo damage or automatically regularise a planning breach. The appropriate response depends on what has happened, the planning status and what the Local Planning Authority requires.

    Do you cover Surrey, London, Sussex, Hampshire and Kent?

    Yes. Arbor Cultural provides arboricultural planning and construction-stage consultancy across those areas and the wider South East. Send the site postcode if you want us to confirm coverage.
