Rodents are a major problem on farms and present a threat to food security as well as human and animal health and welfare. Rats alone cost the UK about £200M a year by consuming and contaminating growing and stored crops. The problem is primarily managed, with varying degrees of success, by using anticoagulant rodenticides.
However, these chemicals are economically, ethically and environmentally problematic because they are markedly inhumane, resistance is a growing problem and their usage leads to widespread exposure of non-target wildlife, including threatened species of birds and mammals. In Britain, studies show that most polecats, barn owls and red kites are now exposed to rodenticides, with implications for their conservation. Guidance is available for the improved usage of rodenticides on farms, but we know relatively little about how this guidance works in practice and what improvements remain still to be made. The use of innovative and, in some cases, non-lethal Integrated Pest Management techniques, holds potential for increasing efficacy while reducing the multiple problems of established practices for rodent control, including the risks rodenticides pose to wildlife.
This CASE studentship will provide training in the science underpinning sustainable agriculture and food security by working towards more effective, economic and humane management of wildlife in the farm environment. The student will undertake evaluations of variation in rodent control practices and outcomes, conduct experiments on current and innovative approaches to rodent management and model approaches and outcomes to enhance best practice. They will adopt an interdisciplinary approach to research on wild animal populations and behaviour and on farmers and contractors and their practices and will work in the field and laboratory. The student will join a large group of interdisciplinary, applied researchers (wildlifescience.org) in Professor Robbie McDonald’s research group at the University of Exeter’s Penryn Campus and will work alongside Professor Richard Shore at the Centre for Ecology and Hydrology (ceh.ac.uk) and Alexandra Tomlinson and Ruth Layton at our CASE partners sankalpa (oursankalpa.org).
