Glossary

Biodiversity Accounting Tool: A spreadsheet tool used to calculate the habitat biodiversity impact of a development.

  1. Biodiversity Accounting Payment: The element of a financial contribution that covers the costs to find, establish and pay for the management of a Biodiversity Accounting Scheme.
  2. Biodiversity Accounting Scheme: A scheme that will deliver biodiversity enhancements that shall not be less than the Residual Habitat Impact Score.
  3. Biodiversity Financial Contribution: The contribution due by the developer for a specific Biodiversity Accounting Scheme.
  4. Biodiversity Impact Assessment: The process of evaluating the habitat biodiversity impact of a development.
  5. Baseline Value: Biodiversity value of the current habitat on the offset site in Biodiversity Units.
  6. Biodiversity Loss: A negative Biodiversity Unit score.
  7. Biodiversity offset brokers: These intermediary players can support the biodiversity offset system by registering potential offset sites and matching them to the needs of the developers and local planning authorities. They can also facilitate the development of offset arrangements on new land.
  8. Biodiversity Units: A measure of the biodiversity loss or gain calculated as the product of the area, condition and distinctiveness of the habitat lost.
  9. Condition: The state of habitat, which includes their physical, chemical, and biological characteristics.
  10. Construction and Environmental Management Plan: A condition placed on an approved planning application to secure nature conservation during the construction phase of the development.
  11. Contingency Payment: The element of a financial contribution that will be used to secure additional biodiversity enhancements should any Biodiversity Accounting Schemes not fulfil their ecological objectives.
  12. Distinctiveness: A collective measure of biodiversity and includes parameters such as species richness, diversity, rarity and the degree to which a habitat supports species rarely found in other habitats.
  13. Ecosystem Services: Processes by which the environment produces resources utilised by humans, such as clean air, water, food, and materials.
  14. Landscape and Ecology Management Plan: A condition placed on an approved planning application to secure nature conservation after the construction phase of the development has finished
  15. Management and monitoring Payment: The element of a financial contribution that will be used to cover the costs associated with collecting data, managing, monitoring, reporting and regulating the progress of Biodiversity Accounting Schemes.
  16. Priority Habitats and Species: Species and habitats published in the UK Biodiversity Action Plan as conservation priorities which are under threat because of their rarity and rate of decline. Those found in England continue to be regarded as conservation priorities in the subsequent UK Post-2010 Biodiversity Framework as habitats and species of principal importance.
  17. Receptor Site: The land where the Biodiversity Accounting Scheme will be delivered.
  18. Risk Factors Include delivery risk, spatial risk and temporal risk: These are multipliers within the metric calculation that help manage ecological risks associated with offset delivery.
  19. Target Habitat: The habitat to be created or enhanced by the proposed offset.
