Looking for some handy tips for starting your career in ecology or ornithology? (We all had to start somewhere!) Here are some handy hints here

David MacArthur


David is an experienced ecologist and company Director with over 20 years’ experience in the environmental sector.

David founded MacArthur Green in spring 2009 with a vision of building a leading specialist ornithological and ecological consultancy with the purpose of working with key partners and clients to have a positive impact on the environment. This involved helping important projects succeed (such as renewable energy developments) and supporting industry research and guidance to inform best practice.

David is recognised as one of the leaders in his field within the renewables industry. He has experience as an expert witness in both ornithology and ecology and his combined understanding of these issues can deliver considerable value for clients.

Before MacArthur Green David worked with the Scottish Government’s statutory nature conservation advisor (Scottish Natural Heritage) and with ScottishPower Renewables as their Senior Ecologist.

During his time with ScottishPower Renewables, David was responsible for managing ecological and environmental policy issues and working closely with key statutory and non-statutory stakeholders.  At Scottish Natural Heritage David held various roles.  These included Natura 2000 officer with responsibility for designating National and European Sites (SSSIs, SACs and SPAs) and an Area officer advising on fisheries and wind farm developments.

David graduated from the University of Edinburgh in 1998 with a degree in Ecological Science with honours in Wildlife and Fisheries Management. He went on to gain a Diploma in Economics (with Distinction) with The Open University. He subsequently gained a Masters in Economics (with Distinction) from the University of Strathclyde, specialising in environmental regulation and policy.
