Environmental Surveys & Reports

Ecology surveys assess whether development is likely to have an adverse impact on the surrounding wildlife or habitats. They’re very important because the findings can place significant constraints on planned works. In fact, they are often needed before a planning application is submitted

Planning Applications require a variety of Environmental Assessments and Technical Reports to ensure issues are taken into consideration when determining new Plan-ning Applications. There’s now a myriad of subjects that a planning officer can re-quire more detailed information on, these reports are only usually acceptable when carried out by qualified 3rd party.

If you’re looking to make a planning application for a new dwelling, convert an out-building or carry out more significant works such as site redevelopment, demolition of existing buildings etc then you will doubtless need to supply some of the reports listed:

BS5837 Tree Survey, Tree Constraints Plan

BS5837 tree surveys and tree constraints plan drawings are required for most planning applications where trees are on or adjacent to your site

Arboricultural Method Statement, Tree Protection Plan

Often though not always, your local planning authority will want to see a drawing and statement to demonstrate how good quality trees will be retained and protected throughout your development. This is where a Arboricultural Method Statement, Tree Protection Plan is needed

Mortgage Tree Report

If you own property / land or are thinking about buying, and you have trees or vegetation in close proximity to your property, sometimes your insurer or mortgage provider will request the mortgage tree report.

Preliminary Ecological Appraisal

A Preliminary Ecological Appraisal (PEA) is the most commonly requested survey at project planning stage. It looks at the habitats and vegetation that are present on the site and surrounding areas. Furthermore, it looks at those that could be present. The assessment involves:

Gathering baseline ecological data. This is done via a desktop study and a walkover survey.

Identifying key constraints on the proposed development.

Identifying any mitigation measures.

Highlighting enhancement measures.

Recommending whether additional, more detailed surveys are needed.

Extended Phase 1 Habitat Survey

Part of the PEA, this survey involves mapping and describing the identified habitats.

Ecological Walkover Survey

An ecological walkover survey is a quick, cost effective appraisal of an area. It identifies the habitats and species present (or likely to be present).

Protected species survey

Sometimes, initial ecology surveys indicate the presence of protected species. In these cases, a protected species survey is a legal requirement. The type of survey and the mitigation needed will vary. That’s because it depends on the species identified:


Great crested newts




Water voles

Checks for nesting birds.
