Biodiversity Net Gain (BNG), underpinned by the Environment Act 2021, is an approach which aims to produce a measurable benefit to biodiversity through development.
BNG requires a 10% increase in biodiversity value, measured using the Natural England metric calculation tool.
How is it assessed?
A feasibility (stage 1) assessment is used to determine the baseline value of a site, based on a UKHab habitat survey. From this, we can advise whether the scheme is likely to achieve a net gain and make recommendations to deliver the best result possible. This is beneficial when scoping out sites or for an outline application.
A design stage assessment (stage 2) also assesses the baseline of a site and then uses fixed landscape proposals to calculate the change in biodiversity between pre- and post-development landscapes. A 30-year management plan is also required following a design stage assessment.
Our expertise
Our team of experts will support your development through the entire process from feasibility stage to completion. All consultants are trained in the UKHab survey method for accurately classifying habitats and work closely with our in-house GIS team to ensure that spatial accuracy is maintained from the field to report stage. We also liaise with landscape architects to inform design and produce holistic developments which are beneficial to both communities and local biodiversity.
BNG is a complex matter and, at first glance, can seem daunting. To help you and your team understand BNG and how to deliver it, we can provide an informative CPD webinar covering everything you and your team need to know about BNG and its mechanisms for delivery.
