As we look back on the first anniversary of the UK’s Biodiversity Net Gain (BNG) policy, Vertical Meadow stands at the forefront of integrating genuine ecological value into urban landscapes. Our living walls transcend mere aesthetics; they serve as vital habitats that contribute directly to biodiversity enhancement.
Understanding Biodiversity Net Gain
The BNG policy, enacted in February 2024, mandates that new developments achieve at least a 10% net increase in biodiversity compared to pre-development conditions. This initiative aims to ensure that development projects not only minimise environmental harm but also contribute positively to ecological networks. The policy offers flexibility in achieving this gain, allowing for on-site enhancements or the purchase of biodiversity units from third parties.
The Value and Criticisms of BNG
While BNG represents a progressive step towards sustainable development, it has been met with both commendation and critique. Proponents argue that BNG provides a structured framework for integrating nature into urban planning, fostering habitats, and enhancing ecosystem services. For instance, some renewable energy projects are aiming for biodiversity uplifts of 100%, significantly exceeding the mandatory 10%, thereby contributing substantially to local ecosystems. Reuters
However, critics express concerns regarding the policy’s implementation and effectiveness. A study revealed that housebuilders in England have delivered only about half of the promised nature-friendly features, such as trees and bird boxes, in new developments. This shortfall highlights challenges in enforcement and the need for more stringent compliance mechanisms to ensure that biodiversity commitments are met. The Guardian
Vertical Meadow’s Commitment to BNG
At Vertical Meadow, we recognise both the potential and the challenges of the BNG policy. Our approach is designed to not only meet but exceed BNG requirements through innovative and ecologically sound practices.
Exclusive Use of Native Species
A fundamental criterion for achieving a ‘Good’ condition under the statutory biodiversity metric is the complete absence of invasive non-native species. Many conventional living walls incorporate ornamental or non-native plants, which may not support local wildlife and can even become invasive. In contrast, Vertical Meadow’s systems utilise 100% native species, ensuring full compliance with BNG standards and providing appropriate habitats for local fauna.
On-Site Seed Cultivation
Our methodology involves cultivating plants directly from seed on-site. This approach creates lighter, thinner living walls that adapt better to their environments than traditional pre-grown plant systems. By allowing plants to develop in situ, we enhance their resilience and reduce maintenance needs, thereby supporting long-term ecological integrity.
Enhancing Urban Biodiversity
Over the past year, our installations have played a pivotal role in restoring biodiversity within urban settings. Our living walls act as ‘stepping stones’ for nature. They facilitate species movement and connectivity across fragmented habitats, strengthening urban ecosystems. These green infrastructures not only support wildlife but also offer ecosystem services such as improved air quality and climate regulation.
Looking Ahead
BNG lays a foundation for biodiversity in development, but its success relies on effective implementation and enforcement. Vertical Meadow is committed to advancing urban greening. Our practices are rooted in ecological principles and deliver measurable biodiversity benefits.
