For the last decade Ronni has looked after the ecological management of this site which has a range of freshwater and terrestrial habitats, is biodiverse and packed with protected species. 

Research interests include urban river pollution; impacts of flood and drought on aquatic habitats and their species; impacts of sewage spills and misconnections; macroinvertebrate community compostiion change over time; biodiversity; river restoration; rearing of aquatic invertebrates; impacts of non native species and habitat management. She was the first to successfully breed our native freshwater crayfish in captivity and is the Hertfordshire County recorder for Trichoptera (caddis) and Plecoptera (stoneflies).  She is in the process of writing up results of long term data on caddis life history tables and urban river ecology monitoring of invertebrate communites, chemistry and coliforms. Dr Edmonds-Brown is a member of the British Ecological Society (BES) and for the last 20 years managed the aquatic ecology groups JISCMAIL (membership). She is also a member of the Freshwater Biological Association and sits on numerous committess related to environmental issues.
