Badger Cull

Debate between Meg Munn and Angela Smith

Thursday 13th March 2014 Commons Chamber

[Angela Smith]

The hon. Gentleman has anticipated much of what I am going to say about the constructive way forward.

The first and most important point to make about the pilot culls relates to the meeting of the scientific experts convened by DEFRA in April 2011, which drew two key conclusions about the pilot culls. The first was that the culls needed to be

“conducted in a co-ordinated, sustained and simultaneous manner”

over a short time period in order to minimise potential impacts of perturbation. The second key point was that

“the more that a future culling policy deviates from the conditions of the RBCT…the more likely it is that the effects of that policy will differ”.

Those two important points are at the heart of today’s debate. They explain why a target was set of a 70% reduction in badger density in the cull areas in six weeks, but we find—this is not because of the independent expert panel report—that Natural England withdrew licences after 11 weeks of culling in both zones because it was evident that there was no hope of reaching the target number of badgers.

I wish briefly to address why the targets of 70% and six weeks were chosen. The six-week target was set by DEFRA in the context of the lessons learned by the RBCT, which found that the proactive culls that were completed across entire areas in eight to 11 nights had a much higher likelihood of delivering a positive impact than the prolonged culls—the reactive culls that took place—over more than 12 nights. The risk of the latter is that TB in badgers is further elevated and thus it is expected that any benefits in relation to reducing cattle TB are undermined.

[Meg Munn (Sheffield, Heeley) (Lab/Co-op)]

The number of badgers in the area was one of the issues raised in previous debates. Obviously, the 70% target is dependent on having a reasonable estimate of the number of badgers in a particular area, and I understood that not to be available.

[Angela Smith]

This is the “badgers moving the goalposts” argument, which repeatedly comes back to haunt this debate. The important thing is to have accurate numbers, not least because we do not want to break the Bern convention, and therefore the law, in terms of taking the risk of eradicating an entire species.

On four occasions, the RBCT conducted non-simultaneous culls—this comes back to the point about the short period of time, as they went on over a prolonged period. It was found—the evidence is there—that there was an increase in the proportion of badgers infected, over and above the background norm of the increase in numbers infected by the proactive culling.

In 2010, DEFRA’s science advisory council said:

“There is little useful data on the issue of what time period should be considered as ‘simultaneous’. The Group advised that if culling was carried out in a period of up to 6 weeks (although preferably less), that is likely to reduce the adverse effects of non-simultaneous culling; this advice is based on opinion and not on evidence. The longer the period that culling is carried out in, the less confident one can be that the deleterious effects seen with non-simultaneous culling as carried out in the RBCT will be minimized.”

That is from DEFRA’s own science advisory council. It is absolutely clear that the pilot culls took a fairly significant risk in planning to meet the six-week target. The fact that they failed comprehensively to meet that target supports the claim in the independent expert panel report that the pilot culls were ineffective; they took 63 and 77 nights respectively. Remember that the randomised badger culling trial found that to maximise impact, a cull should take place over eight to 11 nights.
