Tree 21 provides tree surveys, reports and advice on trees and woodlands in relation to planning and development.

We cover all sizes of projects from domestic projects of one single tree, to large major developments with several hundred or thousand trees.


We can help support your project and the tree issues, from pre-acquisition, to the planning process, right through to supervision of construction with careful methodology around trees. 

Please contact us for further information and to discuss your requirements and we will advise accordingly!

Tree Survey (British Standard BS5837:2012)

Using specialist software, our surveys are efficient and cost effective. Typically, we require a topographical survey base plan provided as a .dwg/.dxf file, correctly scaled and orientated to OSGB and a survey boundary.  Our survey data is captured on site and uploaded to a cloud based secure server. This ensures that your data is safely stored and can be accessed at any point throughout the project.


Every tree/tree group within gthe red line is plotted on the base plan and relevant data is recorded, including at least one photograph of each tree.      


​The output is a Tree Constraints Plan, provided in .dwg and .pdf format, along with a Tree Data Schedule provided as a .pdf file. This information can be provided as a standalone BS5837 Tree Survey or within an Arboricultural Constraints Report and Subsequently used to inform an Arboricultural Impact Assessment or Arboricultural Method Statement.

Arboricultural Impact Assessment

This is the usual standard report which a Local Authority requests to support and validate a planning application as part of the consultation process when there are trees on or near the land.


The report needs to be supported by a Tree constraints Plan (tree survey plan) and a Tree Protection Plan which illustrates the design against the tree survey plan and which trees will be lost, protected and retained.

Arboricultural Constraints Report

This report provides advice and information relating to the constraints on site posed by trees. Consideration to the tree values, ground levels, hydrology, soil condition, local and wider landscapes, statutory constraints (Tree Preservation Orders & Conservation Areas), Veteran & Ancient Trees and Woodland (and the additional constraints these pose) are all covered with relevant photographs provided where appropriate.


This report is always recommended to those considering developing areas of land with many trees, or woodlands present to enable thorough understanding of the tree constraints and space development space limitations they may cause. This information can be invaluable further down the line.

Arboricultural Method Statement

​This document can only be provided once there is an understanding of the impact upon trees. Where higher value trees are to be retained, but there is conflict with the development layout, a Local Authority may request an AMS to provide specific detail on how works will be achieved without damaging retained trees. 


This document provides detailed methodology and recognised engineering solutions with sequenced tasks and details on arboricultural supervision to ensure any potential tree damage is minimised.


An AMS is often a request via a planning condition, however, this can also be provided up front along with the AIA, if there is tree conflict to reduce construction programme issues. We always flag this, if it becomes applicable during the AIA process.      

What Our Clients Say

Paul Whale, Studio 83

""I have worked with Mike on a number of projects over the past few years and have found him to be approachable, knowledgeable, experienced and professional.  He offers practical solutions to perceived difficulties and is quite willing to discuss ideas and to guide through the necessary stages of the works.  He is always willing to take on board concerns with a view to overcoming difficulties before presenting his recommendations, and has advice invaluable.  His reports are very detailed, technically accurate, simply explained, neat and easily readable. I have been impressed at how quickly has has acted to make sure there are no delays. If no additional information has been requested Mike has carried out the revisions without any fuss and within an agreed time schedule and fee costing. 

When the reports have been presented to local Authorities consent has been able obtained with little or no changes having to be made.  I would have no reservation in recommending Mike to any of my Clients and would not have any hesitation in using his services again."
