What Developers Need to Know About Off-Site Biodiversity Units for BNG.
A Comprehensive Guide to Off-Site Units from Integrated Land Management
Understanding the Process, Benefits, and Key Steps for Successful BNG Compliance.
Introduction
Biodiversity Net Gain (BNG) is a government policy in England that mandates developers to enhance biodiversity as part of their projects. This means creating or enhancing habitats to offset any loss of biodiversity caused by the development. While on-site improvements are to be prioritised first, off-site biodiversity units play a crucial role in achieving the mandated 10% net gain when this isn’t possible to achieve on-site. This guide delves into off-site biodiversity units, offering a detailed exploration of their role, measurement, and practical application for developers.
What are off-site biodiversity units?
Off-site biodiversity units represent habitat creation or enhancement projects undertaken on land separate from the development site (land separate is outside the red line boundary of the development that has planning permission requiring BNG). For the purposes of BNG, biodiversity value is measured in standardised biodiversity units using the Statutory Biodiversity Metric.
By purchasing off-site biodiversity units, developers can offset the negative impacts of their projects and contribute to broader landscape-scale conservation efforts.
How do off-site biodiversity units work?
Off-site biodiversity units can be created and sold from a Biodiversity Gain Site, the process typically involves the following steps:
Baseline Habitat Survey: An initial assessment of the land’s biodiversity value and potential unit availability is conducted using the Defra Statutory Biodiversity Metric.
Habitat Enhancement or Creation: Suitable habitats are identified for introduction and enhancement to increase the existing biodiversity value.
Biodiversity Unit Valuation: The Metric is used to calculate the number of biodiversity units generated by the habitat creation or enhancement project.
Biodiversity Gain Site Registration: The land is registered as a Biodiversity Gain Site on the national register.
Unit Sale: Biodiversity units can be sold to developers who require them to offset the biodiversity loss of their projects and meet their 10% net gain requirement
Long-Term Management: A robust habitat management plan is implemented to ensure the created habitats are managed and maintained for a minimum of 30 years.
By purchasing these off-site biodiversity units, developers can contribute to broader landscape-scale conservation efforts while fulfilling their BNG obligations. It's important to note that the value of biodiversity units can vary depending on factors such as habitat type, location, and size.
Benefits of Off-Site Biodiversity Units for Landowners
By creating and managing Biodiversity Gain Sites, landowners can:
Generate an Additional Income Stream: Generating revenue from biodiversity units can provide a valuable source of income.
Contribute to Landscape-Scale Conservation: Support broader efforts to protect and enhance biodiversity.
Promote Sustainable Land Management: Encouraging biodiversity-friendly practices can improve soil health and water retention.
Diversification: Reduce reliance on traditional agricultural practices and diversify income streams.
Challenges and Considerations
While off-site biodiversity units offer numerous advantages, it's essential to be aware of potential challenges and they must only be considered after all on-site options have been exhausted.
At ILM, we understand these challenges and have developed strategies to mitigate them. Our expertise in BNG and strong industry relationships enable us to provide tailored solutions that address your specific needs.
