General Ecology & Planning FAQs

What ecological surveys do you offer?

We provide a range of ecological surveys, including Preliminary Ecological Appraisals (PEA), Protected Species Surveys (e.g., bats, great crested newts, badgers, reptiles), and Biodiversity Net Gain (BNG) Assessments.

When do I need an ecological survey for planning?

You’ll need an ecology survey if your project involves land development, protected species, or potential habitat loss. Local planning authorities require biodiversity assessments to comply with UK wildlife legislation and planning policy.

What is a Preliminary Ecological Appraisal (PEA)?

A PEA survey (or Phase 1 Habitat Survey) is an initial site assessment to identify ecological constraints, such as habitats and protected species. It helps determine if further protected species surveys are required.

What is Biodiversity Net Gain (BNG)?

Biodiversity Net Gain (BNG) ensures that developments leave the environment in a better ecological state. Under UK law, most developments must demonstrate a 10% net gain in biodiversity through habitat creation and enhancement.

How long does an ecological survey take?

The timeline varies depending on the survey type. PEA surveys can be completed within two weeks, while protected species surveys (e.g., for bats and great crested newts) require seasonal assessments, taking several months. For more information on seasonal restrictions see our Survey Calendar

What happens if protected species are found on my site?

If protected species are present, mitigation measures may be needed, such as habitat creation, licensing from Natural England, or modifications to development plans.

Biodiversity Net Gain (BNG) & Habitat Creation

How do you calculate Biodiversity Net Gain (BNG)?

BNG is measured using the Defra Biodiversity Metric, which assesses habitat condition, distinctiveness, and connectivity. We provide BNG assessments to ensure compliance with local planning authorities and UK law.

What are habitat banks, and how do they help with BNG?

Habitat banks are areas of land managed to provide biodiversity offsetting. Developers can purchase BNG credits to meet biodiversity targets if on-site net gain isn’t achievable.

Planning & Development Compliance

What ecological reports do councils require for planning applications?

Councils typically require:

  • Preliminary Ecological Appraisal (PEA)

  • Protected Species Surveys (e.g., bats, badgers, GCN)

  • Biodiversity Net Gain (BNG) Assessment

What happens if an ecology report is missing from my planning application?

Missing ecological reports can lead to planning permission delays or refusals. Our team ensures your project meets all ecological and BNG requirements.

Do you liaise with local councils and Natural England?

Yes, we work closely with local planning authorities, Natural England, and other regulatory bodies to ensure compliance with UK wildlife laws.
