Ecology Services

Ecological surveys assess the levels of nature and habitats on a site and their implications for a development.

We work on a huge variety of projects, from a single extension for a private homeowner through to major developments, renewable energy schemes and national infrastructure.

Every survey follows current legislation and guidance, precisely cited and properly applied, written up in plain English so no client needs to become an ecologist to understand what it means. A named ecologist manages your project throughout, from first site visit to report delivery and beyond.

Our Services:

Preliminary Ecological Appraisal (PEA)

A first look at a site's ecological features and constraints, usually the starting point for any planning application. Get an instant online quote using our PEA tool.

Ecological Impact Assessment (EcIA)

A detailed assessment of how a proposed development is likely to affect habitats and species, and what mitigation addresses that impact. Often required once a PEA has flagged a likely effect.

Protected species surveys

Targeted surveys for bats, birds, badgers, dormice, great crested newts, otters, water voles and reptiles, each following the relevant national guidance. Confirms whether a protected species is present, and what a project needs to do about it.

Green Infrastructure Statements

Required for all Welsh planning applications under Planning Policy Wales 2024. Sets out how a development incorporates green infrastructure such as trees, planting and sustainable drainage.

Biodiversity Statement

Requested by some local authorities to demonstrate how a development will deliver a benefit for biodiversity, alongside or instead of a formal net gain calculation.

Supporting discharging planning conditions

Documentation such as Reasonable Avoidance Measures Schemes and Biosecurity Risk Assessments, prepared to satisfy the ecological conditions attached to a planning permission.

BREEAM assessments

Input under the Land Use and Ecology category, prepared to support a BREEAM (Building Research Establishment Environmental Assessment Method) rating.

Net benefit for biodiversity

Calculations and reporting aligned to Planning Policy Wales and the Environment (Wales) Act 2016, showing a development leaves biodiversity in a better state than it found it.

Biodiversity Benchmark accreditation support

Support toward Biodiversity Benchmark, the Wildlife Trust's own standard certifying that a business site is managed well for wildlife.

Building with Nature accreditation support

Support toward Building with Nature, the UK's first green infrastructure benchmark for the built environment.

Arboricultural surveys

Typically a BS5837 Tree Survey Report, assessing trees on a site ahead of a planning application.

Ecological Clerk of Works (ECoW)

On-site supervision once planning permission is granted, checking that works follow the agreed reports and legislation as a project is delivered.
