Biodiversity net gain (BNG) is a mandatory requirement for developers to ensure that their development projects increase the overall biodiversity value of a site. The strategic significance in biodiversity net gain calculations refers to the consideration of the ecological importance, connectivity, and condition of habitats in order to achieve a measurable net gain. It involves assessing the existing biodiversity value of a site, setting targets for net gain, and implementing measures to enhance or create habitats. The strategic significance lies in preserving and enhancing the natural environment, promoting ecological resilience, and contributing to the conservation and restoration of priority habitats and species.
Biodiversity net gain is an approach to development and land management that aims to leave the natural environment in a measurably better state than before. It is supported by the National Planning Policy Framework (NPPF), which calls for the minimization of impacts on biodiversity and the provision of net gains. The mitigation hierarchy is an important principle in biodiversity net gain, which prioritizes the avoidance of impacts, followed by mitigation and compensation. Ecological networks that are more resilient to current and future pressures are also key components of biodiversity net gain.
“Biodiversity net gain is an approach to development and land management that aims to leave the natural environment in a measurably better state than before.”
The NPPF provides guidance for local planning authorities and developers on how to achieve biodiversity net gain, ensuring that developments contribute to the overall enhancement of biodiversity.

Biodiversity net gain encompasses both on-site and off-site measures to achieve the required increase in overall biodiversity value. Understanding the distinction between these two approaches is crucial in effectively implementing biodiversity net gain.
On-site biodiversity net gain refers to the measures taken within the red line boundary of a development project to enhance or create habitats. The red line boundary defines the physical area where the development is planned or taking place. On-site measures can include habitat restoration, creation of wildlife corridors, and planting native vegetation within the project’s boundary. These actions directly contribute to the net gain target and help to improve the ecological value of the development site.
In contrast, off-site biodiversity net gain encompasses actions taken outside the red line boundary, regardless of ownership. It involves measures such as habitat restoration in nearby locations, creation of nature reserves, or the enhancement of existing ecological networks. Off-site measures are essential for situations where there may be constraints on implementing net gain within the development site or where there are opportunities to enhance biodiversity in adjacent areas. By considering off-site options, developers can ensure that they are making a positive contribution to biodiversity even beyond their immediate project area.
Both on-site and off-site biodiversity net gain measures are essential in achieving the mandatory net gain requirement set out in the Environment Act. By implementing a combination of these measures, developers can play a significant role in enhancing biodiversity and contributing to the conservation of priority habitats and species.
Here are some examples of on-site and off-site biodiversity net gain actions:
By implementing a combination of these measures, developers can have a positive impact on biodiversity and help create a more sustainable future.

|Actions taken within the red line boundary of a development project to enhance or create habitats.
|Actions taken outside the red line boundary, regardless of ownership, to enhance biodiversity.
|Restoring degraded habitats, creating wildlife corridors, and planting native vegetation within the project’s boundary.
|Restoring nearby habitats, creating nature reserves, and enhancing ecological networks in adjacent areas.
|Directly contributes to the net gain target and improves the ecological value of the development site.
|Expands the impact beyond the immediate project area, contributing to the conservation of priority habitats and species.
By considering both on-site and off-site measures, developers can ensure the effective implementation of biodiversity net gain and make a significant positive impact on the natural environment.
The Biodiversity Metric, developed by Natural England, plays a crucial role in determining the biodiversity value of a site for net gain calculations. This habitat-based approach measures the changes in biodiversity value resulting from development or changes in land management. The latest version of the Biodiversity Metric is Biodiversity Metric 4.0, which assesses the pre- and post-development biodiversity value of habitats and determines the biodiversity uplift.
The Biodiversity Metric takes into account various factors, including habitat extent, distinctiveness, condition, and strategic significance. By considering these factors, the Biodiversity Metric provides a comprehensive assessment of the proxy biodiversity value of a site. It enables developers and planning authorities to measure the impact of their projects on biodiversity and set targets for achieving net gain.
The Biodiversity Metric is a powerful tool in ensuring that development projects contribute to biodiversity conservation and restoration. By incorporating the strategic significance of habitats, it helps guide decisions on habitat enhancement and creation, promoting ecological resilience and supporting the conservation of priority habitats and species.
The Biodiversity Metric 4.0 is designed to be user-friendly and accessible to a range of stakeholders involved in development projects. Its use enables a standardized and transparent approach to net gain calculations, providing a common language and framework for evaluating biodiversity outcomes. By utilizing the Biodiversity Metric, developers can demonstrate their commitment to enhancing biodiversity and achieving measurable net gain in line with the mandatory requirements.
|Biodiversity Metric Factors
|Measures the size or area of habitats on a site.

|Assesses the ecological health and quality of habitats.
|Takes into account the ecological importance and connectivity of habitats in achieving net gain.
The biodiversity gain plan is a crucial document required for development subject to mandatory biodiversity net gain. It plays a vital role in outlining how the development will deliver biodiversity net gain and is submitted for planning authority approval. The plan encompasses various aspects, including minimizing impacts on habitats, assessing the pre- and post-development biodiversity value of onsite habitat, considering offsite habitat provided in relation to the development, and accounting for statutory biodiversity credits.
The approval process for the biodiversity gain plan ensures that the proposed development aligns with the biodiversity gain objective and complies with additional requirements set out in applicable secondary legislation. It aims to strike a balance between meeting the development goals and achieving the mandatory biodiversity net gain, contributing to the conservation and restoration of priority habitats and species.
To develop an effective biodiversity gain plan, developers and planning authorities must consider the pre-development biodiversity value of the site, which serves as a baseline for measuring net gains. This baseline assessment helps set targets for achieving a measurable increase in biodiversity value after the development. By assessing the post-development biodiversity value, the plan can determine the effectiveness of the measures implemented and ensure that the development achieves the required net gain.

|Determine the effectiveness of measures implemented
|Enhance biodiversity beyond the development site
|Compensate for unavoidable biodiversity losses
The biodiversity gain plan acts as a roadmap for development projects to achieve biodiversity net gain while ensuring that ecological considerations are prioritized and integrated into the design and implementation process. By following the requirements outlined in the plan and obtaining planning authority approval, developers can demonstrate their commitment to sustainable development and contribute to the conservation and enhancement of biodiversity in the local area.
The National Biodiversity Credits Scheme is a crucial component of the mandatory biodiversity net gain framework. This scheme provides a mechanism for developers to achieve the required net gains by purchasing statutory biodiversity credits if they are unable to achieve the necessary biodiversity enhancements on-site or through the off-site market. The credits are sold by the UK government, with Natural England responsible for the sales process.
The scheme is designed to encourage the creation and restoration of habitats that promote biodiversity net gain. Developers who participate in the scheme can contribute to habitat creation projects that provide significant ecological benefits. The credits purchased by developers represent the biodiversity gain achieved through these habitat creation projects. By participating in the scheme, developers can fulfill their net gain requirements while supporting the conservation and restoration of priority habitats and species.
Indicative credit prices have been published by Defra, providing developers with a clear understanding of the costs associated with achieving biodiversity net gain through the National Biodiversity Credits Scheme. These prices reflect the value of the biodiversity improvements delivered by the habitat creation projects and are set higher than market prices for equivalent biodiversity gain. The higher prices incentivize developers to prioritize on-site enhancements and only utilize the credits scheme when necessary, ensuring a greater focus on sustainable development practices.
|Credit Price (per unit)
|Category A – Priority Habitats
|Category B – Other Habitats
|Category C – Species
As the implementation of the National Biodiversity Credits Scheme progresses, a digital sales platform will be developed to streamline the process of purchasing statutory biodiversity credits. This digital platform will provide a user-friendly interface for developers to browse available credits and facilitate transactions. It will enhance the accessibility and efficiency of the credits scheme, making it easier for developers to fulfill their biodiversity net gain obligations.
The implementation of mandatory biodiversity net gain, as outlined in the Environment Act, recognizes the importance of preserving and enhancing the natural environment. However, certain exemptions exist to allow for the protection of irreplaceable habitats. These exemptions, defined in secondary legislation, will include a list of habitat types considered irreplaceable. The government plans to consult on this definition and seek input on the proposed list, ensuring a comprehensive and informed approach to habitat conservation.
It is essential to note that biodiversity net gain provisions apply to England only. Scotland has its own approach, tailored to its unique environmental circumstances. Additionally, marine development is currently excluded from the mandatory biodiversity net gain requirement. This exclusion is due to the less developed metrics for assessing marine habitats and environments. As research and understanding of marine biodiversity metrics progress, it is possible that the inclusion of marine development in biodiversity net gain calculations may be considered in the future.
“The exemptions for irreplaceable habitats demonstrate the delicate balance between development and conservation. By consulting on the proposed list, the government aims to ensure that the most precious habitats are protected and sustained for future generations.”
Protecting irreplaceable habitats is a crucial aspect of biodiversity conservation. These habitats play a significant role in supporting unique species and maintaining ecological balance. Exempting such habitats from net gain calculations recognizes their inherent value and the need for targeted preservation efforts. By consulting on the proposed list of irreplaceable habitat types and engaging stakeholders in the decision-making process, the government strives to ensure transparency, fairness, and effective environmental stewardship.
