Predicting the changes in farm syrphid faunas that could be caused by changes in farm management regimes (Diptera, Syrphidae)
Data on habitat associations coded into a computerised database of information about European Syrphidae are used, together with information on the habitats present on a farm, to predict the likely future of the observed syrphid fauna of the farm under various management regimes. Most of the observed species appear to be dependent on habitats occurring in non-productive parts of the farm and it is predicted that loss of these habitats through intensification of use of the farm could reduce the existing syrphid fauna by more than 80 %. It is also apparent that financially viable management options are not available, to ensure the survival of the existing farm fauna, which would be expected to diminish by at least 20 % in consequence.
