Foxes & agriculture: Overview
The
impact of foxes on agriculture is a
controversial issue. In general, farmers
perceive any predator as a pest because of
losses suffered by their livestock. However,
several studies on the economic role of foxes
have highlighted some interesting findings
which are explored in detail in this section on
foxes and agriculture.
Each year, rabbits cause an
estimated £120
million of damage to
agriculture in Britain. Foxes cause an
estimated £12
million of damage but this needs to be
put in perspective, because rabbits are the
main prey of foxes in rural areas. By eating
rabbits, foxes provide an indirect economic
benefit to farmers of at least
£7
million annually. Because fox benefits
offset their costs, foxes are probably
economically neutral to farmers.
Research on lamb, poultry and piglets
shows that losses to foxes are, in general, low
and that simple measure to improve husbandry
may effectively reduce predation. Pheasant losses
to foxes are low in release pens but there are
limited data on predation after release, when
losses are slightly higher. However, since
estates release a large surplus of birds (only
about 40% of those released are shot), the
economic impact of fox predation on released
pheasants is probably small. To increase pheasant populations
in the autumn, estates can either control foxes by shooting them
or release more birds, for those estates that rely on rearing game.
