We are a company of like-minded specialists who work in partnership with you to deliver your objectives.

Thomson Ecology

Thomson Ecology was founded in 2004 by Nancy Thomson (CEO) and John Mundy, quickly followed by Richard Arnold as Technical Director. The three shared a vision to provide excellence and innovation in all aspects of ecology and biodiversity.

Today, with over 100 permanent staff, our expertise covers terrestrial ecology, marine services, freshwater ecology and management, laboratory analysis, habitat creation and management, geospatial data management and mapping, arboriculture, and landscape architecture.


Our relationship with Imperial College London and our award-winning Thomson Interactive Mapping platform are just two examples of our focus on new technology and innovation, improving efficiency and reducing costs.

Supporting our community

We believe in giving back to our local community, particularly through education. Our interactive school visits encourage the next generation to be curious about the natural world and biodiversity.

Our partner

All new construction projects have to pass specific ecological and archaeological requirements before they receive planning permission. Our alliance with Wessex Archaeology places us in a strong competitive position, as together we offer the breadth of an even wider set of skills and the in depth knowledge of highly experienced specialists.

The partnership offers developers a more efficient and streamlined method for commissioning these specialist services, allowing access to the best advice available as part of one contract without the need to go to multiple firms.
