The government’s chief scientist has advised ministers
that a badger cull would reduce the spread of the bovine
tuberculosis in heavily affected areas.
Sir David King, the chief scientist, in effect paves the way for
a government-approved cull of badgers in the worst affected areas
such as the South West and south-west central England and South
Wales.
But he advises that any cull must be accompanied by a series of
tough cattle controls for it to be successful.
Sir David’s report is largely based on the Independent
Scientific Group on cattle TB’s final report on the Randomised
Badger Culling Trial, published in June, and other associated
studies.
Interestingly, however, Sir David did not consider the Four Area
Trial conducted in the Republic of Ireland.
His report appears to contradict the ISG’s conclusions that a
badger cull would only serve to make the situation worse by
increasing the distances roamed by the remaining badgers.
But, in contrast, Sir David concluded that culling would be
beneficial in areas surrounded by hard physical boundaries, such as
coastline and motorways.
Sir David King’s conclusions
• Badgers are a clear source of infection for cattle. Reducing
the density of badgers in those areas of England where there is a
significant level of TB in cattle reduces the incidence of TB in
cattle in the same area;
• Removal of badgers should take place alongside the continued
application of controls on cattle. Genuine commitment by all
interested parties to the overall TB strategy is needed if TB is to
be successfully controlled;
• Removal of badgers is the best option available at the moment
to reduce the reservoir of infection in wildlife. But in the longer
term, alternative or additional means of controlling TB in badgers,
such as vaccination, may become available. Research into these
should continue;
• Removal of badgers should only take place in those areas of
the country where there is a high and persistent incidence of TB in
cattle. It is not an appropriate measure in other areas;
• The minimum overall area within which badger removal should
take place is 100 km2, although increasing the area would increase
the overall benefit;
• Where there is inaccessible land within the overall removal
area, badgers should be removed on the accessible land bordering
it;
