Abstract: Traffic accidents with wild boar have increased rapidly over the last years in Sweden. This paper calculates and predicts costs of current and future accidents, totally and for different Swedish counties, based on estimates of wild boar populations. A logistic population model is assumed, and econometric methods are used for calculating populations with panel data on traffic accidents, traffic load, hunting pressure, and landscape characteristics for each county. The results show an annual average growth rate of 0.48, which varies between 0.39 and 0.52 for different counties. This, together with predictions on changes in traffic load, forms the basis for calculations of costs of traffic accidents for a 10 year period. In total, the predicted costs can increase from 60 million SEK in 2011 to 135 or 340 million SEK in 2021 in present value depending on assumed hunting pressure. The variation is, however, large among counties; costs can increase by ten times in Stockholm and Södermanland where the wild boar populations are relatively small and by 50% in counties with mature populations.

Keywords: traffic accidents; costs; wild boar; econometrics; land scape characteristics; Sweden.
