BSG Ecology is a leading independent ecological consultancy. We provide a complete ecology service, from fieldwork and baseline survey to impact assessment, biodiversity management, project design and expert witness advice. We employ a large team of dedicated ecologists and have a strong desire to do interesting and challenging work.


The practice was established in 1997 by three founding partners, all practicing ecologists, with backgrounds in conservation, research and consultancy – it has grown steadily, we now have four partners and we employ nearly forty people in five offices across the UK and one in Ireland. The practice is still ecologist-owned – we are science-led at all levels.

Our approach to consultancy

BSG Ecology has a proven record of successfully tackling complex ecological issues on a wide range of projects. Scientific rigour, sound defensible advice, pragmatism, clarity of thought and commercial awareness underpin our approach. We focus on building positive professional relationships and have numerous long-term clients.

We believe that relevant and effective consultancy advice needs to have wildlife legislation and policy as its basis. This allows our clients to clearly understand the merits of their options, and to better assess their next steps.

We are committed to providing high quality work. We routinely invest in training and research to strengthen the basis of our advice.  We operate our own internal technical standards and a rigorous peer review process. Our ecologists are bound by the Chartered Institute of Ecology and Environmental Management’s (CIEEM) code of professional conduct.

Our experience

BSG Ecology has a wealth of experience: a portfolio of well over 6,000 projects from major new developments (such as housing, energy and transport), to significant biodiversity research, local authority support, and work for private clients on many protected species. Our key work sectors include renewable energy, utilities, mineral extraction, infrastructure, residential and commercial development and site management.

We are experienced professional ecologists. BSG Ecology has in-house specialists in a wide range of technical disciplines: birds, bats, botany, invertebrates, great crested newts, reptiles, impact assessment, habitat management and creation, biodiversity action planning and offsetting, green infrastructure and GIS.
