Our specialist ecological consultants can survey for a range of protected species and advise on a wide variety of ecological considerations. We use our survey results to inform planning applications, prepare management plans, identify suitable mitigation requirements and monitor the success of management practices.  We advise on practical and effective design solutions for your proposed development to ensure the smooth delivery of your projects.

As part of our Preliminary Ecological Appraisals, we will assess habitats for their suitability for protected species, search for historical species records and make recommendations on project delivery to ensure Local Planning Authorities have the right information to assess your planning application.  Click on the species below for more information.

Specialist species surveys that we offer include:

If your project has the potential to affect badgers then you will need a Badger Survey. Surveys can be undertaken at any time of the year but the optimal seasons are during spring and autumn. Badger surveys are required to identify whether the species is present or likely absent, and assess sett activity levels.  Find out more…

You will need bat surveys if you are planning a development that could harm or disturb bats or their roosts. This can include re-tiling work, an extension on a building, or developments that involve demolition of a building or felling of trees.

Roost assessments can be carried out at any time of year, but emergence surveys are restricted to when bats are active: From May until September. Find out more…

You will need Great Crested Newts Surveys if you are planning a development that could harm or disturb Great Crested Newts. For example, developments that contain suitable habitats (eg. log and rubble piles) or those within 500m of a pond are higher risk for Great Crested Newts. For some developments, protected species surveys will be required to get planning permission.

Great Crested Newt Surveys can only be conducted during a short window in the year: eDNA can only be done between 15th April and 30th June; trapping and torch surveys can be done between mid-March and mid-June. Find out more…

N.B. If your development is in one of the qualifying boroughs, District Licensing may be more appropriate. Find out more about District Licencing here.

If you are planning works on a site which includes, can affect indirectly or is adjacent to a suitable habitat for Otters (like a water body) you will need a specialist survey. Find out more…

You will need reptile surveys if you are planning a development that could harm or disturb reptiles. For example, developments that contain suitable habitats (eg. log and rubble piles, long grass, areas of direct sunlight) are higher risk for reptile species. For some developments, protected species surveys will be required to get planning permission.

Reptile surveys can be conducted between April and September, but conditions are sub-optimal in June and July due to high summer temperatures. Due to this, surveys during this period will be less conclusive about absence or population size, and a precautionary stance is more likely to be needed. Find out more…

You will need surveys for Roman snails if you are planning to conduct works on a site that is likely to contain Roman snails, such that they may be killed or injured, or may require translocation. They can be found in a variety of habitats, but are specifically known to inhabit areas with chalky soils (eg. chalk quarries and the North Downs). Find out more…

Generally development works affect disturbance to the river bank with the consequential destruction of crayfish refuges or water pollution from sediment release. If planned works will have a negative impacts for crayfish and/or its habitat you can contact Surrey Wildlife Trust Ecology Services for an Ecological Impact Assessment report and for helping you to plan any further action. Find out more…

You will need bird surveys if you are planning works or developments that will affect wild birds, particularly those identified those in Schedule 1 of the Wildlife and Countryside Act, and particularly during breeding season. This includes developments that will damage or remove breeding sites (eg. soil stripping in ground nesting habitats or removing trees), disturb birds and their young, or demolish or change buildings or natural features that birds use.

The summer survey season for breeding birds is between March and August. For over-wintering birds, the survey season is between November and February. Find out more…

Phase II botanical surveys are referred to as National Vegetation Classification (NVC) surveys.  They are usually undertaken to inform management plans and Ecological Impact Assessments.  NVC surveys are usually undertaken between April and August. Find out more…

Terrestrial and aquatic surveys are usually undertaken to inform management plans and Ecological Impact Assessments. Invertebrate surveys are usually undertaken between April and October. Find out more…

Sites of Nature Conservation Importance (SNCI) are protected under local planning policies.  We survey these for private individuals and Local Planning Authorities to assess whether their condition still meets the listing criteria.  Find out more…
