Green-tech delivers BNG Solutions map

Green-tech delivers BNG Solutions map: The Government’s Biodiversity Net Gain (BNG) policy is effective from today (Monday 12th February)

BNG is an approach to development, and management, that aims to leave the natural environment in a measurably better state than it was beforehand.

As of today, residential developments with 10 or more dwellings, or where the site area is greater than 0.5 hectares, will have to deliver net gains for biodiversity leading to positive outcomes for nature, better places for local communities, and more consistent and transparent requirements for developers.

Under mandatory BNG, all developments in England must replace any biodiversity lost and add a minimum of 10% biodiversity to provide a net gain. The resulting habitat will be secured for at least 30 years via planning obligations or conservation covenants, enforced by s106 agreements.

A brand of leading landscape supplier Green-tech, the team at John Chambers Wildflower Seed has worked with Bridgman and Bridgman to design a new BNG biodiverse green roof mixture.

Bridgman and Bridgman are specialists in the creation of sustainable living roofs. They trialled the wildflower seed mix to ascertain the best-performing species.

The final mixture comprises 40 species of native wildflower to ensure at least 25 species are present once the roof is established to meet the new legislation. The seed mix should be complimented with native sedum and dry grassland species as described in the guidelines.

John Chambers Wildflower Seed Technical Manager Georgia Gilbert explains, “The final mix contains native wildflower seed to combat the huge declines we have seen due to habitat loss, chemical use, and climate change. Native species are incredibly valuable for our native wildlife. We also chose species that are suitable and perform well in green roof structures – ones that are drought tolerant, suitable for full sun and exposed conditions, and thrive in lightweight substrate.”

Green-tech’s Business Development Director Mark Wood, adds, “Like many others in the industry, Green-tech has been planning for Biodiversity Net Gain and the introduction of the Government’s mandatory BNG policy. We have developed an interactive Biodiversity Net Gain map for use alongside the Biodiversity Metric to contribute to different design options, in the creation of a Nature Positive design. We aim to create a collaborative approach with an overview of enabling nature to thrive through considerate development. Users can view the map at https://www.gtspecifier.co.uk/interactive-map/ simply click on the map and they  will find an abundance of information and resources to help ensure their project is BNG compliant.”
