Biodiversity Baseline Surveys

Robust insight to support your development’s BNG (Biodiversity Net Gain) journey.

Establishing an accurate baseline for biodiversity is essential for calculating BNG and securing planning approval for road upgrades, new build infrastructure and asset renewals.

Our experienced ecologists undertake detailed site assessments using the latest UK Habitat classification and Defra Metric tools guidance, to meticulously baseline existing habitats and species and establish a robust pre-development biodiversity value.

This critical baseline data is the essential foundation and early clarity for your development and land management projects. The data, with its accurate BNG calculations, informs and guides responsible project design, and ensures your full compliance with statutory requirements, mitigating any ecological risks from the outset.

Our biodiversity baseline survey service features:

• Comprehensive habitat surveys following UKHab methodology to provide Habitat Classification (UKHab / Phase 1)
• Condition assessments and stratification suitable for the BNG metric
• GIS mapping and constraint identification
• A precise, comprehensive baseline report that gives full confidence in your BNG calculations
• Legislation-Compliant Reporting (BS 42020, CIEEM)
