      "The Broads Authority has contracted work to ECON for over 20 years. Contracts have included fish and bird surveys right through to comprehensive shallow lake ecosystem research. The ECON team offers not only intelligent review of complex lake and river restoration issues and excellent assessment of results but also the ability to clearly present the information to wide audience. We value the longstanding relationship we have developed with ECON and our procurement process has, on all occasions, found them to be the best option."

      "I have worked closely with ECON on a number of offshore wind farm projects, specifically in The Wash and the Firth of Forth, over the last five years in my capacity as an ornithology consultant managing the Environmental Statement production and Section 36 consents process on behalf of clients.

      During this period, I have reviewed a large number of technical reports, research reports and ES chapters produced by ECON. In every case, the product has been of exceptionally high quality. In relation to similar ornithology reports, ECON's work is distinguished in my view, because it provide information in the context of a clear understanding of seabird ecology, population trends and causes of change.

      ECON has extensive knowledge of ornithology in relation to the offshore wind industry. The company has worked on offshore wind projects located in a range of geographic areas around the UK and for a number of different developers. It is therefore well-appraised of the conservation issues relating to seabirds and offshore wind farms both before, during and after construction. Because it is a consultancy which is also involved in seabird research (other than that undertaken for developers) it has an excellent knowledge of current research and conservation measures both in general and in relation to offshore wind in particular.

      The quality of ECON's written work is extremely high. It always shows a good understanding of client requirements and therefore delivers a targeted product. Working relationships are good as evidenced in meetings with clients, advisers and regulatory bodies."

      "I have known and worked with Martin Perrow since 1993 when he helped with my undergraduate dissertation on blue-green algae cycles in Norfolk shallow lakes. In 1999, just after my PhD, I commissioned ECON to undertake point-sample electro-fishing fish surveys of 30 shallow lakes as part of a research fellowship at University College London (UCL). Put simply ECON did the best possible job and the resulting data, which were of the highest quality, formed the basis of five subsequent journal articles, much expanding our knowledge of fish responses to eutrophication and macrophyte loss.

      ECON have also collaborated with UCL's in-house consultancy ENSIS on a number of conservation-led research projects focused on lake and associated freshwater wetlands. In this capacity I have worked with ECON on three occasions, with ECON undertaking fish and birds work and UCL undertaking macrophyte surveys. The resulting work represents some of the most satisfying and highest quality research that I have been involved in, with this especially true of a project focused on the necessity for sediment removal in Upton Great Broad, Norfolk.

      ECON stand apart from other consultancies for a number of reasons. Firstly they are 100% passionate about nature conservation and are driven by a strong desire to conserve and restore aquatic habitats and assist declining species. They are experts when it comes to setting up scientifically-sound sampling programmes, even for very difficult to sample organisms such as fish and birds. They have considerable experience with running successful projects that are underpinned by an incredible depth of scientific knowledge and so resulting conservation advice is always on a very solid footing. Finally, since those early meetings with Martin Perrow, I have found Martin and all ECON staff incredibly supportive and friendly. They are great to collaborate with and always come through with fantastic work. I feel privileged to have worked with them and hope I can continue to do so well into the future."
