Biodiversity Net Gain (BNG) is a conservation approach that ensures development projects leave the natural environment in a measurably better state than it was before. It’s not just about reducing harm —it’s about giving back more to nature than is taken away.
Under the UK’s Environment Act, BNG is now a legal requirement for many types of development —meaning biodiversity loss must be offset with tangible, trackable ecological improvements.
Traditional development often comes at a cost to nature. BNG shifts this paradigm, embedding ecological thinking into the planning process and offering a pathway to balance growth with genuine environmental benefit.
We help clients understand, achieve, and demonstrate Biodiversity Net Gain on their projects —from initial assessments to long-term monitoring. Our approach blends field ecology with cutting-edge tools and deep policy knowledge.

We know that delivering BNG isn’t just about ticking a box —it’s about making sure nature thrives alongside human progress. Our team understands both the science and the regulatory landscape, helping clients not just meet BNG requirements, but exceed them in ways that make ecological and business sense.
At Symbiosis Associates, we believe in working with nature, not against it. Our philosophy is rooted in deep ecology, which sees the natural world as interconnected and valuable in its own right.
