Abstract: Field boundaries are important habitats for birds within the agricultural landscape. In this study, bird surveys were carried out during the winter and breeding season on nine farms in the east and south-east of Ireland and field boundaries at each site were assessed using the Field Boundary Evaluation and Grading System (FBEGS). Poisson regression demonstrated that FBEGS scores were a good predictor of both winter and breeding bird species richness and diversity within the field boundaries studied. We interpret these preliminary results with caution since our sample size was relatively small (compared to the wide variety of field boundary types found in Ireland) and no single combination of field boundary attributes is likely to be optimum for all bird species. However, our results suggest that FBEGS may be a useful surrogate indicator of overall field boundary bird diversity and we discuss the consequent implications for agri-environmental policy, and for the possible adaptation and use of FBEGS as a tool to monitor the impact of changing farm management practice.
