Maximising biodiversity net gain: A collaborative approach for lasting impact

James Hewetson-Brown, Managing Director

Wildflower Turf Ltd

There has been a lot happening with biodiversity net gain (BNG) and this initiative is getting widely accepted – it must, it’s now a legal requirement! At Wildflower Turf Ltd, we have run a couple of BNG events and are delighted to have had Nick White attend (amongst others) as a guest speaker on both. We have heard some very interesting insights as a result and wanted to share some that are particularly relevant to us.  

It was agreed that BNG is now accepted as a force for good and it should be a powerful tool to improve biodiversity. The metric is widely understood (it takes a bit of practice!) and there are good examples of real-life case studies out there. The acceptance and value of the initiative was brought home when we heard how much international interest it was having. Sections of it are being digested and copied by other countries who are modelling their equivalent schemes on the UK scheme. Whilst there are examples of actual BNG projects out there it was agreed that there is still a lot to learn and BNG will continue to develop and improve.

One area of discussion followed the need for a team mindset. But it was clear that the current thinking on this to date has revolved around those involved at the start of the process. While developers, ecologists, landscape architects, landowners, and local planning authorities are typically involved from the outset, the long-term success of BNG projects depends on the quality of materials, habitat establishment, and ongoing management. My thoughts are that one critical aspect often overlooked is the role of suppliers and contractors. They too should be included at the outset.

Suppliers play a vital role in providing the right “source materials” that are essential for creating thriving habitats. Contractors are responsible for implementing the establishment plan correctly, ensuring proper maintenance to guarantee that the habitat remains for 30 years to meet the audit requirements. By involving suppliers and contractors early in the process, teams can ensure that the BNG project is not only compliant but also delivers lasting environmental benefits.

To achieve successful BNG outcomes, a team approach is essential. Habitat won’t happen overnight, and to establish good quality habitat, BNG projects will need clear objectives, well-planned establishment strategies, high-quality materials, and effective post-establishment management. These are all critical components for success. Wildflowers and species rich grasslands are a major habitat in BNG and are our area of expertise. We know how to grow them, we know how to enhance them, and we know how to look after them. To establish a good quality grassland habitat, we would advise the below:

• Team involvement: Include supplier and contractors from the project’s inception.

• Clear objective: Define specific outcomes and ensure shared understanding among all stakeholders.

• Establishment plan: Carefully consider habitat suitability, accessibility, and public engagement. Put wildflowers in areas that suit them and the wildlife they will generate. Plan access for people to allow for an un-invasive yet immersive experience that ensures the buy-in of locals to help guarantee long-term success.

• High-quality materials: Use the right source material or products - In our case Wildflower Turf®, Meadowscape Pro™ or Wildflower MeadowSow™ Seed – all native to the UK and with UK provenance.

• Post-establishment management: Develop a comprehensive plan, ensure those doing it understand it, and provide necessary resources (e.g. right machinery) and training. Where site managers change over time, make sure

  there are good handover notes and processes.

There are many factors that will make a successful project and a pragmatic and practical approach to delivering BNG is essential for success. By adopting a collaborative and proactive approach, we can ensure that BNG becomes a powerful tool for enhancing biodiversity and creating a more sustainable future, that meets and exceeds the 30-year mandate.
