The ups and downs in the advancement of biodiversity enhancement projects
In the realm of UK development, the implementation of Biodiversity Net Gain (BNG) has become mandatory for major developments since February 12th, with small sites following suit on April 2nd. This new policy aims to ensure a positive impact on biodiversity, but finding registered offsetting sites for BNG has proven to be a complex task.
One of the main obstacles is the limited availability and access to suitable off-site sites. When onsite BNG is not possible, developers must find off-site habitat enhancement or creation sites. However, identifying and securing appropriate off-site locations can be difficult due to limited supply, lack of coordination, or complex ownership arrangements. This challenge is particularly acute for smaller developments, which are sometimes exempt or face difficulties in navigating the BNG requirements.
Another issue lies in the inconsistencies and exemptions for small or minor developments. Approximately 87% of planning applications are exempt from BNG, often including smaller scale projects. While this is meant to reduce burden, it risks cumulative biodiversity harms and undermines the overall effectiveness of BNG policies. Such exemptions limit the demand and market for offsetting sites and complicate market predictability.
To address these challenges, several solutions and approaches have been proposed. Early and integrated planning encourages developers to consider BNG from the earliest stages of site selection and design, facilitating the identification of potential onsite and offsite opportunities. Improving coordination and standardization aims to coordinate BNG research and promote best practices for consistent implementation across scales and sectors. This includes improving data on habitat availability, monitoring outcomes, and regulatory frameworks.
Supporting small and medium developments involves policy refinements to streamline BNG compliance while maintaining credibility and encouraging small site contributions to net gain. This could involve official support, simplifying pathways, and enabling better access to offsite offsetting opportunities. Leveraging trusted partnerships, such as private landowners, conservation bodies, and established offset providers, can also help secure high-quality offset sites that align with the biodiversity gain and mitigation hierarchy.
As the deadline for small site submissions approaches, the urgency of finding registered offsetting sites highlights the need for these solutions. The success of BNG hinges on appropriate design, preparing designs that are maintainable in perpetuity, and clear management plans for a 30-year period. With the right approach, the planning and development industry believes that once the issues related to BNG are ironed out, the standard of new development will improve exponentially.
- To mitigate the complications faced by smaller developments and encourage compliance, it is crucial to refine policies for supporting small and medium-sized projects, enabling easier access to offsite offsetting opportunities.
- As the science behind environmental-science and the financial implications of BNG become better understood, promoting best practices in data collection, monitoring, and standardization will contribute to creating a transparent market for offsetting sites, thereby addressing the inconsistencies and exemptions in policies.
