Traditional orchard agroecology
Sustainable water management
Current / Recent Research
I currently work on a Leverhulme funded project investigating the ecology and conservation of the Noble Chafer (Gnorimus nobilis) in collaboration with Prof Jon Sadler and Dr Lloyd Jenkins. This species particularly favours veteran trees in traditionally managed orchards. Changing agroeconomic practices have increasingly meant the loss and decline of such traditional orchards, and the Noble Chafer has declined as a result. The study examines the ecology of this species and how the attitudes and management practices of local stakeholders influence its conservation.
I previously worked on the Big Lottery funded Open Air Laboratories (OPAL) project as a community scientist for the OPAL West Midlands region. This involved helping local community groups to better understand and appreciate the wildlife in their local green spaces. The principle method used was a citizen science approach whereby I facilitated community participation in scientific projects like the OPAL Soil, Air, Water, Biodiversity, Weather and Bugs Count surveys; or my own research on urban ecology. Ongoing citizen science research includes collaboration with the Garden Moth Scheme to explore the garden and landscape scale controls on garden moth assemblages.
In collaboration with Prof Jon Sadler, James Hale, Dr Richard Greswell and Prof Rae Mackay I am researching the urban ecology of various species and habitats, but in particular, bees and the ecology of green roofs. The global rate of urbanization is accelerating, resulting in the disturbance and fragmentation of habitat across larger and larger areas. Some species are able to flourish, whilst others decline in urban habitats, which in turn influence the community health and consequent provision of ecosystem services. Bees are the most important group of pollinators, so they are critical components of a healthy urban ecosystem. Understanding how they respond to the pressures of urbanization is of key importance. Green roofs are novel habitats in urban areas that can potentially provide replacement habitat lost to development, whilst reducing urban run-off and mitigating the heat island effect. My research focuses on the design of green roofs to mitigate for the loss of brownfield habitat.
My PhD research was on the ecology and conservation of specialist invertebrates of exposed riverine sediments (ERS) and I continue my interest in this field in collaboration with Prof Jon Sadler, Prof David Hannah, Prof Klement Tockner, and Dr Simone Langhans. I am particularly interested in aquatic terrestrial interactions of ERS assemblages, their spatial organisation, and their conservation in the face of numerous threats.
