Ecology Surveys
Our experienced and friendly team of ecological consultants offer a range of ecology surveys to clients all over the UK, with the underlying intention of satisfying local planning authorities, providing adequate ecological mitigation, and supporting planning applications.
Our biodiversity net gain plans and reports help you to quickly understand the BNG implications on your site so you can reduce risk and save money. Hundreds of 5-Star Reviews can’t be wrong!
Whenever priority plant species are on a development site or a planning project affects sensitive sites, national vegetation classification (NVC) is needed. Analyse the British plant communities in and around your planning project with an NVC survey.
Understand all possible ecological constraints on your development site and check if any other ecological surveys are needed with a preliminary ecological appraisal (PEA) from our specialist team.
Often used in a proposed development that could have significant effects on the environment, an ecological impact assessment (EcIA) will support protected species and help local planning authorities to determine planning applications.
A simple, quick and relatively cheap ecological assessment, usually a prelude to sustainability credit reports. We do a field study at your site and provide you with a highly concise report.
Our invasive species surveys apply to all problematic invasive non-native species of plant, such as Japanese knotweed, giant hogweed, Himalayan balsam and injurious weeds.
If there are rare or protected plant species on your development site, you will need habitat and botanical surveys before the local authority will grant planning permission and allow you to move forward. Contact Arbtech today for a botanical survey quote.

Ecology Surveys for Planning and Development
As a developer or planner, you need to balance the success of your property or land development with the impact on the natural environment and all of the important ecological features on your site.
Whenever you propose new developments or regeneration projects, you must account for the habitats and species present. Ecology surveys are the main tool for identifying all ecological assets and seeing the correlation between them and your planning project.
With the help of our team, you can understand how your proposed development project interacts with local wildlife, giving you everything you need to make sure that your application for planning permission meets all of the planning requirements set by your local council.
What is an Ecological Survey?
Also known as an ecology survey, an ecological survey is a professional assessment of a certain area to identify any present animal and plant species that are protected.
The assessment process involves a desk study to review baseline information on existing habitats and a field study to retrieve first-hand evidence from the site itself.
Ecology surveys are the first stage in determining if a proposed site contains notable species of valuable habitats that could impact or be impacted by development proposals.
When is an Ecology Survey Required?
Before you start any work on the site, you need to undertake surveys to continue the planning process without any issues.
An initial survey is almost always needed early in your project. The local planning authority will ask for this report if your site has a potential presence of protected habitats.
It isn’t just about fields, forests and other outdoor spaces either. If your development proposals involve a loft conversion, work on complex tree structures or are near cave-like spaces, for instance, a PRA could be needed to check for bats. Likewise, a wide range of protected species can appear on existing buildings and greenfield or brownfield sites.
By identifying ecological constraints as early as possible, you can plan with certainty and find the best way to move forward without unexpected hitches.
Planning Requiring an Ecological Survey
Most planning applications need relevant information about the ecological conditions of the site before a planning officer can give the go-ahead.
From a small private plot to a large commercial site, survey data helps to determine planning applications faster, such as in the following examples:
Ecological Surveys for Construction, Clearance and Demolition:
The assessments allow development to continue by establishing all potential ecological issues within the site boundary.
With insight into the site’s wildlife features, clearance of the site, construction on the site or demolition of a structure on the site can move forward without endangering any species.
Ecological Surveys for Developments:
Using the expert advice from our trained ecologists to your project team, we can help you to navigate nature conservation laws and the legislation protecting ecological assets.
By following our instructions, developers and planners can avoid the costly delays that come from late-stage discoveries on the site.
Ecological Surveys for Planning Applications:
A professional ecology report is a mandatory requirement when it comes to getting planning permission.
The report gives your local planning authority the confidence that the proposed project complies with the UK Biodiversity Action Plan (UK BAP), National Planning Policy Framework (NPPF), Local Nature Recovery Strategies (LNRS), relevant legislation and all local requirements.
Ecological Surveying
Surveys and reports on a site’s ecology act as a vital tool for understanding how a proposed development site fits into the wider landscape.
Through gathering key information from the site, we can gauge the ecological conditions that will influence the planning project’s design and the likelihood of success.
Importance of an Ecological Survey
Professional assessments lead to pivotal decisions for your project, with the benefits including:
Financial Security
Working out the necessary ecological mitigation requirements early prevents investment in unviable land.
Identifying the potential presence of protected features to avoid a stop-work order.
Environmental Responsibility
Meeting the legally binding environmental targets set to safeguard the environment.
Planning Success
Obtaining the ecological report necessary for the local planning authority to grant planning permission.
Project Continuity
Avoiding potential effects from the late-stage discoveries that could otherwise end up causing massive project delays.
Objectives of an Ecological Survey
The primary goal of our work is to provide a clear and risk-free path to your goals, with the assessments aiming to:
Evaluate Impacts
Predicting the potential impacts that the proposed development could have on the location, especially if the site is on or near:
Ramsar sites
Special Areas of Conservation (SAC)
Special Protection Areas (SPAs)
Sites of Special Scientific Interest (SSSIs)
Local Nature Reserves (LNRs)
National Nature Reserves (NNRs)
Identify Constraints
Defining species found on the site and gauging the potential constraints caused by the development plans.
Design Mitigation
Applying the mitigation hierarchy to formulate suitable mitigation strategies for your planning project.
Achieve Compliance
Meeting the requirements to enable the local authority’s planning department to approve the proposed project, such as with the help of an ecological impact assessment (EcIA) report.
Protect Biodiversity
Mapping out sensitive areas, protected components and priority habitats to prevent top-level biodiversity losses.
Enhance Habitats
Producing specific ways to deliver habitat creation and a net gain in biodiversity to help the natural environment.
Types of Ecological Survey
Different types of ecological services are designed to meet specific needs.
Our team offers a comprehensive selection of assessments, surveys, plans and reports to ensure that your planning project remains compliant.
Ecology Surveys
Known as the first step in the process, ecology surveys identify broad habitat types and evaluate the general potential for ecological assets on a site:
Biodiversity Net Gain (BNG) Assessments
As required by the Environment Act 2021 (formerly the Environment Bill), supporting projects that need to adhere to biodiversity net gain (BNG).
A biodiversity net gain assessment will be needed, followed by the creation of a biodiversity net gain plan. Our team will visit the site to record a pre-development value of biodiversity based on present ecological features, predict the post-development value based on the plans of the project, and work out how to retain the value and build on it by at least 10%.
BREEAM Assessments
Ensuring that the development meets international sustainability standards for the environment and contributes to long-term nature conservation.
Led by a qualified ecologist, a BREEAM assessment will focus on protecting natural assets and implementing habitat creation to raise the project’s sustainability rating.
The EcIA mainly targets the development’s potential impact on the environment. Based on that, suitable mitigation or compensation measures can be chosen.
Ecological Walkover Surveys
Appearing as an early-stage review of the site, an ecological walkover survey will spot the likely ecological constraints.
In simple terms, it will allow ecological surveyors to advise clients on whether additional surveys or other types of further action are needed before the development can continue.
Habitat Regulations Assessments (HRAs)
In any situation where a development could impact sites with special protection, a habitat regulations assessment (HRA) is mandatory.
All the information taken from the assessment will then go on to ensure that the development’s impact on protected sites is addressed under the latest best practice guidelines.
Preliminary Ecological Appraisals (PEAs)
Previously known as an extended phase 1 habitat survey, a preliminary ecological appraisal (PEA) is the most common form of ecology survey.
A PEA is a vital ecological assessment used to map habitat types and determine if surveys are needed for a particular species, such as protected species surveys or invasive species surveys.
Protected Species Surveys
When the initial checks show a presence of protected species, you will need the corresponding detailed surveys to satisfy the law.
By continuing with habitat surveys for the present protected species, it is possible to guarantee that they are managed safely, avoiding any further action from regulators.
Badger Surveys
Checking for signs of badgers, setts and foraging runs under the Protection of Badgers Act 1992 to prevent disturbance.
Barn Owl Surveys
Searching for barn owls in certain sites that could have suitable roosting features, like rural outbuildings and hollow trees.
Searching through hedgerows and wooded areas for dormice to protect any specific locations that are used as nesting and hibernation sites.
Great Crested Newt Surveys
Using environmental DNA (eDNA) surveys to check for great crested newts in ponds and other suitable patches of water on or near the site.
Invertebrate Surveys
Looking through local watercourses and other suitable habitats for various species of terrestrial and aquatic invertebrates, including insects and white-clawed crayfish.
Otter Surveys
Highlighting the presence of holts and resting places for otters in riparian zones on or near the site.
Red Squirrel Surveys
Investigating the area at length for any signs of red squirrels, with a particular focus on woodland and trees.
Reptile Surveys
Putting out artificial refugia to check for snakes, lizards and other reptile species in grassland and scrub.
Water Vole Surveys
Scoping through suitable parts of the site for water voles and their burrows to prevent avoidable habitat destruction.
Invasive Species Surveys and Vegetation Surveys
Following a similar set of steps to protected species surveys, ecology surveys can also lead to invasive non-native species surveys if certain types of plants are seen or suspected.
Advanced Biosecurity Planning and Expert Witness Services
Undertaking a full review of the potential rare plants across the site, a botanical survey looks at the relationship between various plants within local ecosystems.
Giant Hogweed Surveys
Visiting the site to observe giant hogweed before going on to produce a suitable mitigation plan to deal with it correctly.
Himalayan Balsam Surveys
Controlling the spread of Himalayan balsam on the site to protect important habitats that could be damaged as a result of it.
Injurious Weed Surveys
Analysing the site at length for indications of injurious weeds that could pose a threat to protected plants.
Japanese Knotweed Surveys
Setting up effective measures for preventing the spread of Japanese knotweed and stopping the likelihood of structural issues.
National Vegetation Classification (NVC) Surveys
Inspecting all plants across a site, a national vegetation classification survey consists of categorising the specific habitats and working out how to manage them.
Problematic Species Audit
Looking at the site, the present invasive plant species and the development plants, a problematic species audit will determine if further survey work is needed for site clearance.
Problematic Species Management Plans
As part of the process for satisfying a planning condition, problematic species management plans involve designing suitable mitigation and compensation measures for the present non-native invasive species of plant.
Ecological Survey Report
With the ecology report, all of the raw field data is translated into actionable advice for your planning project.
After any of the services above, the ecologist in charge of the assessment will write up an ecological report. It will generally provide information about the type of survey conducted and include a record of the site survey results and findings, as well as the steps needed to enable the plans to continue.
The report has the ability to demonstrate that all requirements were met. With it, you will be able to give your local authority the necessary insight to get planning consent over the line.
Ecological Survey and Assessment
Every ecological survey we undertake follows a structured assessment process.
In the section below, we’ve explained more details of how our project team oversees the ecological survey process, helped by specific benchmarks, field approaches and high-tech tools.
Ecology Survey Checklist and Criteria
For an ecology survey to be valid in the eyes of the planning officer, you must meet the specific criteria set out in the biodiversity checklist provided by your local council. We ensure that the report satisfies the primary factors, as set out below:
Identification of Natural Features – A complete record of all natural features present, from veteran trees and hedgerows to ponds and watercourses
Habitat Connectivity – An evaluation of how your site functions as a corridor for wildlife and its role in local nature recovery
Impact Identification – A clear list of the likely impacts to or from ecological assets that could hinder the build
Statutory Compliance – Verification that the planning project meets all environmental targets and matches national requirements
Ecological Survey Methods
Our ecological consultants approach each and every site using a universal approach to ensure that the results are accurate, only changing the methodology based on the specific type of survey. The methods we utilise include:
Zone of Influence Assessment – An analysis of the wider buffer zone (often between 30m and 500m, depending on the type of species) to see how the project could affect mobile animals or nearby water systems
Systemic Transect Walks – A physical walk of the site via criss-crossed and predetermined paths to guarantee total coverage of all areas
Ground-Truthing – An in-person verification of the desk study to check the woodland shown on an old map, confirming that it’s still there or if it’s changed into a different type of habitat
Target Notes – A record of specific markers for features that don’t fit into a broad category, such as a single tree with a bat-friendly crack or a patch of invasive weeds
Proportional Effort – A principle that ‘the effort must match the risk’, like how a small extension needs a different level of survey effort than a 50-home housing estate
Evidence-Led Scoping – A decision over whether further survey work is needed based on the initial results of the survey
Ecological Survey Techniques
While the methods above account for the strategy we follow, the techniques below cover the actions we take on the ground:
Active Searching and Refugia Checks
eDNA Water Sampling
Nocturnal Emergence Watches
Vocalisation Analysis
Quadrat and Transect Sampling
Nut and Nest Evidence Hunting
Incidental Record Logging
Ecological Survey Equipment
To undertake surveys to a professional standard, our ecological surveyors need to use a wide range of technical tools, including:
Full-Spectrum Bat Detectors
High-Resolution Endoscopes
Sub-Meter GPS Handsets
Thermal Imaging and Night Vision Cameras
Static Acoustic Monitors (SAMs)
Environmental DNA (eDNA) Kits
Refugia (Artificial Mats)
Remote Camera Traps
Botanical Sampling Tools
Ecological Survey Guidelines
For your application for planning permission to be successful, the supporting data needs to be of a high professional standard.
Our team operates under the strict governance of the Chartered Institute of Ecology and Environmental Management (CIEEM) to ensure that our work meets the rigorous code of conduct expected by regulators.
Depending on the location of your site, if a European Protected Species Licence (EPSL) is needed for relocating specific species or destroying habitats and creating new ones elsewhere, we will help you apply for a mitigation licence from Natural England or Natural Resources Wales.
In any type of environmental impact assessment, we align our work with the requirements of the Department for Environment, Food and Rural Affairs (DEFRA).
Under the established standards, we can guarantee that your ecology report provides the same level of detail required by statutory bodies.
Ecology Survey Season
Timing is one of the most important factors when it comes to fitting the necessary ecological surveys into the development process.
Species are found at different times in the year, with their behaviour and hibernation periods affecting when an assessment is suitable.
The ecology survey calendar is an essential part of the process for arranging a protected species survey. As a developer or planner, you will need to cater to the species and plan ahead to avoid costly delays.
Ecology Survey Windows
Securing the best time for a site visit is critical because wildlife activity changes with the weather.
It is a common misconception that all work stops in the cold. In fact, a preliminary roosting assessment (PRA) for roosting bats can be conducted at any time of year. Bat emergence surveys, however, are limited to between May and September as the optimal time and between April and October as the suboptimal time.
While certain field surveys for badger habitat mapping can occur or even be easier during the winter months, assessments for great crested newts are restricted to the optimal periods in the spring and the summer.
If you miss these certain times for habitat surveys, you may have to wait until the next year to complete the necessary surveys. For more information on the various seasons and windows for each species, check out our ecology survey calendar.
