Who we work with

CGO Ecology works in all sectors: public, private, voluntary and academic - in Dorset, across the UK, and globally. Our clients include nature conservation NGOs, statutory bodies, local authorities, developers, engineers, architects, consultancies, and private individuals.

We are particularly experienced in the following sectors:

  • Renewable energy (wind, solar)
  • Transport infrastructure (rail, road)
  • Minerals/aggregates (rock, sand & gravel, china clay, landfill)
  • Construction (residential, schools, utilities, coastal defences)
  • Biodiversity conservation (EPS, SSSIs, Natura 2000, Article 17, AA, research, policy)
  • Habitat restoration, enhancement (heathland, dune, woodland, wetland, grassland).
We can guide you through the protected species issues relating to your projects, and negotiate with statutory bodies, planning authorities and other stakeholders. With biodiversity featuring more heavily in planning policy, clients are under increasing pressure to seek expert guidance in a timely fashion. Call or email to discuss your requirements and ask for a quote.

Our values and policies

We strongly believe in disseminating wildlife and environmental data as widely as possible, for the benefit of nature conservation and public enjoyment. Therefore we comply with CIEEM's Code of Professional Conduct, which requires its members to "wherever possible, make scientific data collected during the course of their professional duties available to others such as records centres." Data-sharing is also a mandatory condition of EPS icensing.

We share our species records with local environmental records centres (LRCs), nature conservation NGOs, and other recording groups. We normally share data annually, around January, in the year after collection.

Our Privacy Policy is to treat all personal data according to the legal requirements of the Data Protection Act 1998, and to commit to client and commercial confidentiality as appropriate. We are an equal-opportunities employer.

We are committed to reducing our carbon footprint and environmental impacts. Our Environmental and Social Responsibility Policy is downloadable here: pdfEnvironmental & Social Responsibility Policy v 07-11-2014.pdf












"We applied to build a barn to be sited on an arable field.  The council asked for a biodiversity appraisal, and placed a short deadline for receipt. We engaged Dr Chris Gleed-Owen who made a site visit within days, and delivered a fully researched report with plans, species list and recommendation a few days later, within the required timescale.  We have therefore avoided the need for extensions and delays.  Thank you Chris.
