Information about biodiversity net gain for ecologists
This page has been created to provide additional information to Ecologists undertaking Biodiversity Net Gain Assessments within Kings Lynn and West Norfolk.
The following points should be given consideration when undertaking such assessments:
- Damage to irreplaceable habitats must be avoided. Where damage to irreplaceable habitats cannot avoided early discussions must be had with the local planning authority.
- Appropriate evidence of competency to undertake Biodiversity Net Gain calculation and design mitigation, management and monitoring schemes must be provided. This will include, but is not limited to, experience with Biodiversity Net Gain schemes and Metric calculations, relevant professional membership and botanical qualifications (FISC).
- Where watercourses are present within the baseline, evidence of Modular River Survey Training (MoRPh) must be provided with the submission of the Metric.
- Species enhancements should not be overlooked but should be incorporated in tandem with Biodiversity Net Gain to maximise benefits and opportunities of the development. This should include integrated bird, bat or insect box provision, hedgehog-friendly fencing.
- Condition assessments must be provided and comments included within the Biodiversity Metric to justify habitat type, condition or strategic significance allocation. Provision of further information within the comments section of any part of the Metric is welcomed and encouraged.
- Strategic Significance for each habitat type must be fully justified within the comments column of the Biodiversity Metric. Local Nature Recovery Strategies (LNRS) are not likely to be published until 2025 so Interim guidance on how to apply strategic significance is provided until that time.
- All Biodiversity Net Gain documents must be consistent with all final versions of project documents that are submitted in support of an application. Any changes to the masterplan must be reflected in the final Metric calculation.
- Software used to measure areas and length included within the Metric should be identified. Measurements should be made using GIS or similar software and follow Natural England guidance to ensure accuracy where possible.
- Where templates are available from DEFRA / CIEEM / Natural England for HMMP and Net Gain Plans these must be used when submitting documents in support of an application. This will aid the review process and avoid delays.
- Where habitats are created inside of residential gardens this is likely to be classified as vegetated garden or un vegetated rather than individual habitat types. This includes any hedgerows, trees, grassland and shrubs within the garden. Any deviation from this must be fully justified within the comments section of the Metric.
