Professor Richard Ennos

Professor Richard Ennos


Richard Ennos is a Professor of Ecological Genetics and now Honorary Fellow at the University of Edinburgh. His broad research interests centre on the integration of genetic and evolutionary approaches into ecology, with special emphasis on how this can contribute to better guidance for conservation and management of plant, and particularly forest tree populations.

Much of Richard’s research has been based in Scotland and has involved native plants (twinflower, aspen, Arran whitebeams) and communities (native woodlands) of conservation concern.  Current interest is in developing sound policies for facilitating genetic adaptation of native tree populations to the twin threats posed by climate change and emerging pathogens.

Richard has long running collaborations with the Royal Botanic Garden Edinburgh, the Centre for Ecology and Hydrology, and Forest Research. He is also a visiting Professor at SRUC.

Dr Alan Fielding - Formerly Manchester Metropolitan University

Profile picture of Alan Fielding

Dr. Alan Fielding was originally a marine algologist (University of Liverpool) but gradually morphed into a conservation biologist with an interest in uplands and data analyses.  Data analysis is a very important part of his work as a researcher and, previously, during a 35 year career as a university lecturer. Alan still retain links with various universities and is currently an external examiner at Newcastle University for their Ecological Monitoring MSc.

In addition to a BSc and PhD, Alan has an MSc in Biological Computation from the University of York obtained during a sabbatical year.

Alan regularly review manuscripts for peer-reviewed journals (British and international) on topics including: golden eagle and hen harrier conservation and ecology; species distribution modelling (particularly methods used to assess the accuracy of the models) and the impact of wind farms on conservation interests.

Alan was the joint author of the two major species conservation frameworks commissioned by SNH (golden eagle and hen harrier). These frameworks were only made possible by a collaborative and cooperative approach with SNH, NGOs and field workers. They integrate a great deal of information from different sources across Scotland and use a wide range of analysis and modelling techniques. He was also a joint author on the 2017 report analysing patterns in the distribution of satellite tags fitted to golden eagles which seemed to cease transmitting in suspicious circumstances.

Alan is a member of the newly formed Raptors and Forests Joint Working Group and is currently involved with analyses examining the relationships between forest schemes and the distributions of hen harriers and golden eagles.

Alan has considerable experience of wind farm environmental impact assessments in Scotland combined with contributions to three significant wind farm monitoring programmes (Edinbane, Clyde and Farr).

Alan is a director of the Highland Renewal charity which manages the Tireragan estate on the very southwest tip of Mull This estate has one the best Atlantic Oak woodlands in Europe combined with breeding golden eagle, hen harrier and merlin. They manage the estate for regeneration, conservation and educational purposes. The estate encompasses wild rocky coastline, upland heath and bog, nationally important native woodland communities and associated wildlife all regenerating to an increasingly natural state. Importantly, and consistent with SNH’s aims and objectives, Highland Renewal is also committed to the promotion of conservation through education and environmental arts.

Prof Xavier Lambin FRSE - University of Aberdeen

Profile picture of Xavier Lambin

Xavier Lambin is an ecologist with a deep interest for population dynamics and conservation. He left Belgium in 1986 after a degree in Zoology at the University of Louvain and many years of involvement with natural history education.  After one year at the University of Oslo, he moved to Vancouver in Canada in 1988 where he did his PhD on the role of kinship amongst females on cooperation and the dynamics of Townsend’s vole populations. He then moved to Scotland in 1993.

Xavier conducts research on both fundamental and highly applied issues in population dynamics. With his team, he seeks to understand how predation, herbivory and parasitism together with animal movement shape the dynamics of animal populations. He uses field experiments and large surveys and the Adaptive Management approach with e.g. field and water voles, birds of prey, pine martens, American mink and people.

Professor Davy McCracken - Professor of Agricultural Ecology at Scotland’s Rural College (SRUC) and Head of SRUC’s Hill & Mountain Research Centre

Professor Davy McCracken

Davy is Professor of Agricultural Ecology at Scotland’s Rural College (SRUC) and Head of SRUC’s Hill & Mountain Research Centre which is based at the 2,200 ha Kirkton & Auchtertyre upland research farms, near Crianlarich.

Davy took over as Head of the Centre in 2013 and has been tasked with raising wider awareness of the agricultural and environmental research and demonstration potential on the farms. For example, SRUC has conducted peatland restoration works on the farms in collaboration with Loch Lomond & Trossachs National Park and SNH’s Peatland Action Programme. The work of the Hill & Mountain Research Centre aims to help address the economic, environmental and social challenges facing hill and mountain land use systems at a Scottish, UK and international level. They regularly host workshops for farmers, crofters and their advisors on agricultural or environmental topics.

Davy conducted his PhD on the red-billed chough on the island of Islay in the late 1980s and has remained closely involved with the long term study of the population dynamics of chough on the island being conducted in collaboration with the Scottish Chough Study Group, Universities of Glasgow and Aberdeen, SNH and RSPB Scotland.

Davy has been investigating the impacts of Common Agricultural Policy on the biodiversity associated with what are now termed High Nature Value farming systems across Europe for over 25 years. He was also a founder member of the European Forum on Nature Conservation & Pastoralism in 1988 and worked closely with that NGO until stepping down to focus on other work commitments in 2016.

Davy has served on a wider range of advisory committees over the years. In addition to the SNH’s Expert Panel, he is currently a member of the Scottish Rural Development Programme (SRDP) 2014-20 Agri-Environment & Climate Monitoring and Evaluation Subgroup, the Scottish Biodiversity Strategy 2020 Science Support Group Group, Scotland’s Moorland Forum, RSPB’s Committee for Scotland and Scottish Wildlife Trust’s Conservation Committee.

Dr. Beth Scott - University of Aberdeen

Dr. Beth Scott

Dr. Beth Scott is a Reader at the University of Aberdeen. Prior to this she was first a Lecturer and then a Senior Lecturer at the University from 2006 to 2014.

Beth currently conducts multi-disciplinary research using her expertise in marine ecology, oceanography and fisheries sciences. Her research identifies general rules in bio-physical oceanographic processes that lead to the creation of hotspots of predator-prey activity. Specifically, her research group defines biological and physical variables that provide the limited, patchy locations and conditions where energy is transferred across trophic levels in marine food webs. Beth's research team uses approaches ranging from the collection and use of fine scale (second by second) information throughout the water column as well as the analysis of large scale (100s or km) long term data sets on spatial and population dynamics.  Both scales of information are also used within simulation modelling methods which are agent based
