Improving management strategies for the red fox by using projection matrixanalysis

The absolute and relative contribution to the finite rate of increase of sp ecific age classes was examined using projection matrix sensitivity and ela sticity analysis for a number of red fox (Vulpes vulpes) populations. The f ox populations that were examined included urban foxes from England, rural foxes from North America and rural foxes from Australia. The youngest age c lasses made the greatest contribution to the finite rate of increase for al l populations studied. A pest management strategy that reduces survivorship and fertility of juvenile and young adult foxes (Age Classes 1 and 2) will be the most effective strategy for reducing a population's finite rate of increase. The results indicate that fertility control may be as effective a s lethal methods for controlling some fox populations.
