We are professionally qualified botanists with a very detailed, extensive and widely recognised knowledge and understanding of British vegetation. We have been working in this field since 1983 and are particularly experienced with the vegetation and flora of northern and western parts of Britain. We provide a range of services including surveys, monitoring projects, education and expert advice. The high quality of our work is recognised by many people and organisations including statutory conservation and land management agencies, conservation-related non-government organisations, and ecological consultancies.

Alison Averis BSc PhD worked as a member of the Nature Conservancy Council Upland Vegetation Survey team in the 1980s and her PhD was a study of the ecology of a community of oceanic liverworts in upland heaths in western Britain. Since the 1990s she has worked in a wider range of habitats in upland and lowland areas of Britain and has also studied vegetation in Ireland, Norway and the Faroe Islands. Alison is also in charge of membership and general administration of the Native Woodland Discussion Group.
Ben Averis BA MPhil worked mainly on woodland vegetation and woodland bryophyte (moss and liverwort) surveys in the 1980s and his MPhil was a study of bryophyte flora and ecology in over 400 woods in the Scottish Highlands and Islands. Since the 1990s he has worked in a very wide range of upland and lowland habitats in Britain and has also surveyed vegetation in Ireland, Norway, the Faroe Islands, France and Japan. Ben is also the newsletter editor for the Native Woodland Discussion Group and was a member of the Scottish Wildlife Trust Rahoy Hills Reserve Management Committee from 2001 to 2017.
We work as a self-employed partnership. We have Public Liability and Professional Indemnity Insurances, Construction Skills Certification Scheme cards and Emergency First Aid at Work certificates. We make risk assessments, emergency plans and lone-working procedures for fieldwork and have sustainability, quality assurance and data protection policies for our work generally.
