Arboricultural Method Statement (AMS)
What is an Arboricultural Method Statement?
An Arboricultural Method Statement (AMS) is a detailed, step-by-step document that outlines exactly how construction works will be carried out in close proximity to retained trees. It acts as a practical manual for site managers and contractors.
Usually required to discharge a specific planning condition, the AMS translates the visual information from the Tree Protection Plan into clear written instructions. It ensures that complex or high-risk activities are completed safely without causing damage to valuable tree roots or canopies.
Why Do You Need an AMS?
Local Planning Authorities frequently attach an AMS requirement as a condition of planning consent. This means that no development, site clearance, or material delivery can legally begin until the AMS has been submitted to and approved by the council.
A well-prepared AMS bridges the gap between planning theory and on-site reality. It provides your building team with foolproof methodologies for working near trees, minimising the risk of accidental damage, project delays, or costly enforcement action.
What is Included in an Arboricultural Method Statement?
Our Arboricultural Method Statements are meticulously written to provide clear, actionable instructions for your contractors. An AMS typically includes:
- Phasing of Works A clear chronological sequence of operations, detailing exactly when tree protection measures must be installed, inspected, and eventually removed.
- Installation of Protection Precise instructions on how to erect protective fencing and lay temporary ground protection to BS 5837:2012 standards.
- Specialist Construction Techniques Detailed methodologies for any approved works within Root Protection Areas, such as hand-digging, using air spades, or installing specialist foundations.
- Arboricultural Supervision A defined schedule of site visits where an arboriculturist will oversee critical phases of work and report compliance back to the local authority.
Frequently Asked Questions
Here are answers to some common questions we receive regarding Arboricultural Method Statements.
When is an Arboricultural Method Statement required?
An AMS is typically required after planning permission has been granted, serving as a formal planning condition that must be discharged before any site works commence. Occasionally, a council may request a preliminary AMS during the initial application phase for highly sensitive sites.
Who is responsible for following the AMS?
Everyone on the site. The main contractor or site manager holds the primary responsibility for ensuring that all personnel, sub-contractors, and delivery drivers strictly adhere to the methodologies laid out in the document.
What is arboricultural supervision?
Certain high-risk activities near trees, such as excavating within a Root Protection Area, must be directly supervised by a qualified arboriculturist. The AMS will outline exactly when this supervision is required. We provide this monitoring service to ensure compliance and reassure the planning authority.
Do I need an AMS if I already have a Tree Protection Plan?
Yes, they usually go hand in hand. The Tree Protection Plan (TPP) is a visual drawing showing where the protection goes, while the AMS provides the written instructions on how to install it and how to work safely around it.
