My research centres upon wetland ecology. Activities form part of a 'Wetland Research Centre' which includes staff from the Departments of Animal and Plant Sciences, Engineering and Geography. 'Pure' research is broadly concerned with identifying factors and processes influencing the composition and distribution of distinctive vegetation types in wetlands (including ontogenic influences as well as current environmental, hydrological and management conditions). An extensive field data resource (FenBASE and BogBASE databases) provides a focus for experimental studes, which have been particularly concerned with the tolerance of wetland plants to waterlogged conditions, especially with regard to reduced phytotoxins. It also provides a basis for much 'applied' research, which is primarily concerned with wetland conservation and, especially, the restoration of wetlands damaged by peat extraction and groundwater abstraction. Current research is concerned with the identification of generic water supply mechanisms to, and within, wetlands in England and Wales and the relationship of this to vegetation patterns.
