Abstract: Competition in ecosystems can occur in different ways and it is especially important to understand the competition due to well-functioning game management in order to predict what will happen to the competitive situation if something change in the ecosystem. Competition between herbivores can limit certain ecosystem services or lead to a reduction in the biodiversity. This essay studied how the fallow deer population corelates with the density of the roe deer population, which is done through analysis of shooting statistics and data from wildlife accidents. Further analysis was made between firing statistics and wildlife accident data to estimate how the population trends develops over time. The result in this essay showed no significant value that there is a competition between fallow deer and roe deer. The result in this essay suggest that the roe deer population do not reduce when the fallow population increase. Additionally, result from this study is that wildlife collision data and shooting statistics can be used to see trends in the development of wildlife populations over time. Previous studies have shown competition between deer and fallow deer. One reason why we have not obtained values for the competition between fallow deer and roe deer could be explained by the fact that fallow deer are often very local and the roe deer’s distribution area is much larger.
