Research ethos

I am a passionate environmentalist with a research interest in aquatic habitats, including ponds, lakes and rivers. I was born in a small Norfolk village surrounded by ponds and developed a very early passion for natural history, especially in freshwaters. I now undertake research into the current-day ecology and ecological history of aquatic habitats and make major efforts to transfer scientific findings into practical conservation and restoration action. I am especially keen on landscape-scale ideas in conservation and in re-wilding approaches that put into place natural recovery processes. My research comes under a number of key themes:

Pond restoration research

A major part of my conservation-led research has been focused on ponds, especially in farmland landscapes. The Pond Restoration Research Group pages give details of this work which includes studies of pond terestralisation, pond restoration by tree and scrub removal, and influences of terrestrialisation, pond management and fish on landscape-scale biodiversity. A major part of this research is focused on the recovery of rare pond species, especially the crucian carp (Carassius carassius), a fish which has been in steep decline in the UK since the 1970s.

Shallow lake ecology and palaeoecology

Research in this field has centred on the interface between contemporary shallow lake ecology and palaeoecology. A key research strand has been the reconstruction of centennial-scale changes to the submerged macrophyte communities of shallow lakes using plant macro-remains. Combined with studies of plant seasonality, this work has alluded to some of the key pathways and mechanisms that underly eutrophication-induced plant loss in shallow lakes. Much work has also focused on the development of new palaeolimnological procedures suitable for analysing lesser studied fossil remains in sediment cores, especially from invertbrates and fishes.

River restoration research

I have a strong interest in the restoration of lowland chalk rivers, inspired by my work with the River Glaven Conservation Group. This research seeks to determine the hydro-ecological consequences of key river restoration techniques, especially river-floodplain re-connection, re-meandering, the use of woody debris as an ecological engineer and the value of installing gravel riffles to assist salmonid spawning.

Conservation of the European eel

Recently I have started some research into the distribution and passage of the European eel in the catchment of the River Glaven, Norfolk. This work is closely linked to a River Glaven Hertage Lottery funded eel project as run by the Norfolk Rivers Trust (NRT). A major focus of this work is the use of headwater ponds and ditch systems by eels and their potential importance for eel conservation. In addition, in association with the NRT, I am undertaking studies of elver migrations. A major source of information for these studies are the stories and experiences provided by local people, especially the great Roger Grady, a retired eel catcher.

I am a great believer in the need to transfer research findings and scientific knowledge into practical conservation action and policy. In these respects I am a regular speaker to local interest groups, natural history societies, landowners and the general public with regards to lake, pond and river conservation. I am a regular adviser to the Natural England, Broads Authority, Norfolk Biodiversity Partnership, National Trust and the Norfolk Rivers Trust on aquatic conservation issues.

I am a co-founder of the River Glaven Conservation Group (RGCG) which has led the way in terms of river-catchment conservation and restoration in East Anglia over the last decade, winning a number of river restoration and biodiversity awards.

I founded the Norfolk Ponds Project in 2014, which aims to promote and enact pond conservation and restoration in Norfolk, whilst influencing UK conservation policy more generally. Myself and UCL student Helen Greaves co-run the project at present with funding support from the Natural Environment Research Council via the UCL Office of the Vice Provost (Research). Each year we arrange pond restoration workshops for landowers and farmers, attend agricultural shows and organise practical pond restoration events.

I have written several popular articles and blog posts to help inform UK aquatic conservation and to publicise UCL research.

In 2015 I received the Provost's award of UCL "Engager of the Year".
