Improving management strategies for the red fox by using projection matrix analysis

In: Wildlife research, Band 28, Heft 4, S. 333

Abstract

The absolute and relative contribution to the finite rate of increase of
specific age classes was examined using projection matrix sensitivity and
elasticity analysis for a number of red fox
(Vulpes vulpes) populations. The fox populations that
were examined included urban foxes from England, rural foxes from North
America and rural foxes from Australia. The youngest age classes made the
greatest contribution to the finite rate of increase for all 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 as lethal
methods for controlling some fox populations.
