Ecology surveys

As specialist environmental consultants, Thomson conduct all types of ecological survey and assessment to support client planning applications. Ecology surveys are completed in order to satisfy planning applications, and detail the characteristics of the proposed site of development in relation to any European Protected Species.

Our team of qualified ecologists undertake a wide and varied range of ecological surveying throughout the year across the UK and beyond.

Ecology surveys we conduct include:

Badger surveys

Where badgers may be affected by a development, our specialists can provide advice on suitable mitigation options and guidance on minimising ecological risk. More about badger surveys.

Bat surveys

All bat species and their roosts are protected by law. Bats may roost in cavities within trees and within man-made structures including, but not limited to, houses, churches, bridges, tunnels and mines. More about bat surveys.

Bird surveys

We undertake all types of bird surveys during both the breeding and non-breeding seasons. Techniques used include common bird census (CBC), vantage point surveys (VPs), point counts, transects, Wetland Bird Surveys (WeBS) and Brown and Shepherd methodology for upland birds.  More on bird surveys.

BREEAM assessments and CfSH

We provide specialised ecological input for BREEAM and Code for Sustainable Homes (CfSH) assessments in line with current technical guidance manuals: BREEAM UK Non-Domestic Refurbishment & Fit-Out 2014 and New Construction 2014 Technical Manual, BREEAM New Construction UK 2011, BREEAM Domestic Refurbishment 2012 and CfSH Technical Guide 2010. More about BREEAM.

Dormice surveys

Where potential hazel dormouse habitat, such as woodland, hedgerow and scrub, is present on a site, particularly within the known range of dormice, surveys should be undertaken to determine their presence or likely absence.  More on dormice surveys.

Fish surveys

We have over 30 years’ experience undertaking specialist fish surveys, in marine, estuarine and freshwater environments. As leading experts in fish taxonomy, we administer the fish component of the National Marine Biological Analytical Quality Control Scheme (NMBAQC) scheme (in terms of Quality Assurance). More on fish surveys.

Great Crested Newt surveys

Great crested newt (GCN) surveys may be required if potentially suitable aquatic or terrestrial habitat exists within or near to a proposed development. Surveys for reptiles are required if development proposals could impact on the species or their habitats. More about Amphibian surveys.

Marine and freshwater invertebrate surveys

The water and laboratory team handles all benthic and epibenthic, and freshwater invertebrate survey requirements. More on marine and freshwater invertebrate surveys.

Otter surveys

Otters favour habitat near fresh water with suitable cover, including coasts and estuaries with fresh water nearby. Therefore, surveys should be undertaken where a development proposal may affect a waterbody. More on otter surveys.

Pine Marten surveys

Pine Martens are the second rarest carnivore in the UK. Surveys should be undertaken where suitable habitat – predominantly heavily wooded or forested areas – occurs within their known range. More about Pine Marten surveys.

Preliminary Ecological Appraisal

A preliminary ecological appraisal (PEA) is normally the first stage in any site assessment. It has two main elements: an ecological desk study and an extended Phase 1 habitat survey. The PEA can be an extremely useful tool for development masterplanning. Read more about Preliminary Ecological Appraisals.

Red Squirrel surveys

Red squirrel distribution has decreased dramatically during the last century and their range continues to contract. Where suitable habitat is present within their known range, surveys to determine presence or likely absence should be undertaken. More about red squirrel surveys.

Reptile surveys

Reptile surveys are required if development proposals could potentially impact on suitable habitat or directly on the species themselves. More on reptile surveys.

Terrestrial invertebrate surveys

Invertebrate surveys can be conducted by our experienced invertebrate specialists to determine whether important invertebrate communities are present on a site, or as part of an ongoing programme of monitoring. Read about terrestrial invertebrate surveys.

Vegetation and habitat surveys

We undertake standard botanical and vegetation surveys for all habitats, including woodland, grassland, heathland, fen and mire. This includes National Vegetation Classification (NVC). We also undertake surveys for aquatic plants. More on vegetation and habitat surveys.

Water Vole surveys

Any watercourse within a proposed development site should be assessed for its potential to support water voles. Read about water vole surveys.
