Ecological Appraisals & Biodiversity Net Gain (BNG)
Ecosphere Ecology provides comprehensive ecology and arboriculture consultancy services tailored to the planning process. With over a decade of experience navigating the planning system and delivering Biodiversity Net Gain (BNG) assessments from its early application in planning, we offer expert, impartial advice at every stage of your planning application.
Preliminary Ecological Appraisal (PEA)
The Preliminary Ecological Appraisal (PEA) provides a critical insight into the habitats and species present on site. The survey records habitat types and extent using the UK Habitat Classification method, identifies potential ecological constraints, and determines the need for targeted protected species surveys. If site plans are known, the surveyor may also assess opportunities for ecological enhancement, post-development.
Where required, an Ecological Impact Assessment (EcIA) is compiled to collate the results of all surveys and assessments, evaluating the project’s significant effects at local, regional, and national scales.
Biodiversity Net Gain (BNG)
Biodiversity Net Gain, now a statutory requirement under the Town and Country Planning Act, requires most developments to return the Site’s biodiversity in a measurably better state (10%) relative to pre-development development condition. Quantification of the site’s biodiversity, measured in units, is calculated using the Defra Metric.
A Biodiversity Net Gain (BNG) impact assessment is informed by correlating the habitat survey and condition assessment results, which provide the site’s baseline Unit score, with the proposed layout. Our approach to BNG is grounded in the application of the mitigation hierarchy, aiming to avoid, or where not possible, minimise impacts on ecologically valuable habitats and features. We advocate for collaboration between relevant disciplines to ensure ecological considerations are integrated during the design stage. This not only supports the principles of BNG, but also leads to lower compensation costs for the end client.
At Ecosphere Ecology, we can assist with all aspects of your Biodiversity Net Gain (BNG) project, from baseline field assessments to mitigation strategy design. We also produce Habitat Management and Monitoring Plans (HMMP) and, where required, facilitate the purchase of off-site units through our Habitat Bank strategic partner.
