Carlos Abrahams is a part-time Lecturer on the BSc Environmental Biology course. He is Module Leader for Regulating Environmental Information and also teaches on the modules Terrestrial Ecosystems, Freshwater Ecosystems, Atmospheric Pollution and Practical Conservation.

Career overview

Carlos works part-time at NTU, alongside his other job as Technical Director in an ecological consultancy – Baker Consultants. He has over twenty-five years experience as an ecologist and environmental manager, including work with public and private sector clients on a diverse range of high profile projects. This has involved ecological survey, environmental impact assessment, design and implementation of mitigation measures and practical site management. He has expertise in the survey, evaluation and management of rare and protected species, habitats and sites and holds Natural England licences for surveying great crested newts, natterjack toads and bats. He has considerable experience in the delivery of ecological services to large engineering projects such as road and rail infrastructure, flood defence schemes, and industrial estates. This has included the production of Environmental Statements for quarries, pipelines, wind energy, residential, commercial and leisure developments.

Research areas

Carlos’ key areas of research are in bioacoustics and wetland ecology. He has carried out research on habitat selection by wetland invertebrates, the landscape ecology of amphibian communities, the vegetation communities of reservoir drawdown zones, and the use of bioacoustics for pond and bird population monitoring. This theoretical base has been closely allied with practical implementation, producing and implementing conservation management plans for a range of sites, such as the regionally important Witches Oak Waters gravel pit restoration scheme. Over recent years he has been increasingly involved in raising awareness and providing training for bioacoustics, including a number of conference presentations and training courses/webinars for CIEEM, BES, UKAN, IoA, Wildlabs, PR Statistics and Wildlife Acoustics.

Carlos is a member of the IUCN SSC Freshwater Plant Specialist Group. He is also a peer reviewer for Water and Environment Journal, Aquatic Ecology, Lakes and Reservoirs: Research and Management and Frontiers in Environmental Science and Engineering.

External activity

Carlos is a member of the Chartered Institute of Ecology and Environmental Management (serving as vice-chair of the Training Education and Career Development Committee), the British Ecological Society, and is a Commission Member - IUCN SSC Freshwater Plant Specialist Group. He is also an  external examiner for Master's level courses at Newcastle University and Bristol University.
