The presence of trees on or near a proposed development site can significantly influence the planning process. Local planning authorities now routinely require a detailed tree survey for planning permission to assess the condition, location, and retention value of existing trees. These surveys provide crucial insights that inform decisions on tree protection, site layout, and long-term management strategies.
At IROS ARB, we specialise in delivering professional tree surveys that meet the British Standard BS5837 and support successful planning applications across the North West.
Whether you’re planning a small extension or a multi-unit housing project, our expertise ensures compliance with local regulations while safeguarding the environmental value of your site.
Understanding BS5837 Tree Surveys
A BS5837 tree survey is designed specifically for development sites and is often a prerequisite for submitting planning applications. This standard outlines how trees should be assessed and categorised based on their physiological and structural condition, life expectancy, and contribution to the local landscape. Unlike general tree inspections, a BS5837 tree survey evaluates trees in the context of the proposed construction, helping to establish whether they can or should be retained.
The survey results are typically used to inform the layout of the development and to produce technical documents like a tree constraints plan. This plan identifies trees’ root protection areas and canopy spreads to ensure new buildings, access routes, and utilities don’t compromise tree health or safety.
Through this process, developers and property owners can make informed decisions that protect trees and reduce the risk of costly delays in the planning process.
The Importance of Arboricultural Impact Assessments
An Arboricultural Impact Assessment (AIA) is an essential follow-up to a BS5837 tree survey. This report examines the potential impacts of the proposed development on retained trees and vice versa. For instance, it considers whether buildings will encroach on tree canopies or root zones and whether trees pose any potential hazards, such as falling branches, that could affect new structures or residents.
The assessment not only identifies potential conflicts but also recommends mitigation strategies to protect trees and maintain compliance with planning policies. In many cases, this includes design amendments or specific construction methodologies to minimise disturbance.
At IROS ARB, our arboricultural impact assessments are created with both the site’s practical needs and its ecological value in mind, allowing developments to proceed sustainably and responsibly.

Tree Protection Plans and Method Statements
When development proposals involve working close to trees, planning authorities often require a Tree Protection Plan (TPP) and an Arboricultural Method Statement (AMS). These documents set out the measures that will be taken to protect trees throughout the construction process. For developers, this not only ensures regulatory compliance but also helps avoid damage that could result in enforcement action or planning refusals.
Key components of effective tree protection documentation include:
This scaled site plan maps out the exact location of tree protection fencing and restricted access zones. It’s used to physically protect the root protection areas and tree crowns during groundworks and other construction activities. The TPP is a key document submitted to planning authorities for approval before any work commences.
The AMS explains how specific construction tasks will be carried out near retained trees without causing harm. It includes details such as no-dig construction techniques, sequencing of works, use of temporary ground protection, and the role of site supervision. A well-prepared AMS demonstrates that your development team understands and respects arboricultural constraints.
Defined in the BS5837 survey, RPAs are critical zones around each tree that must remain untouched. Protecting RPAs prevents root damage that could compromise tree stability or health. Your AMS will include protocols for working within or near these zones, such as hand-digging, protective surfacing, or rerouting utilities.
These documents work in tandem to ensure all retained trees are adequately protected from the first day of site access to final landscaping. At IROS ARB, we produce detailed and enforceable protection plans that are aligned with BS5837 guidelines and accepted by local planning authorities.
How Tree Surveys Support Planning Success
Tree surveys and risk assessments play a pivotal role in helping developers obtain planning permission while minimising the risk of conflict with planning authorities or the public. By thoroughly assessing tree locations, conditions, and potential hazards, we help avoid unexpected delays that can arise from objections, safety concerns, or environmental regulations. A robust tree survey and supporting arboricultural reports ensure your planning application is built on solid, defensible ground.
Beyond compliance, tree surveys allow developers to optimise site layouts and reduce long-term maintenance costs. Identifying which trees are high quality and worth retaining versus those that are low quality or present risks leads to smarter land use decisions. This kind of data-driven decision making ensures that planning proposals align with local biodiversity targets and improve the overall success of your development.
Protecting Trees and Maximising Site Value
Protecting trees isn’t just a matter of regulatory compliance; it’s a smart investment in your site’s appeal and long-term success. Mature trees enhance the aesthetic and ecological value of a property, contributing to higher resale values and better community reception. This is especially important in areas with conservation restrictions, tree preservation orders, or designated green space policies.
At IROS ARB, we help clients balance development ambitions with environmental responsibility. Our tree surveys, protection strategies, and arboricultural expertise provide a comprehensive approach to protecting trees, preserving habitat, and ensuring that every development project we support is both practical and sustainable.
By working closely with developers, local authorities, and tree officers, we ensure all plans are executed to the highest standard.
