Hey Guest, Early bird pricing on the Summer Moot (29th July - 10th August) available until April 6th, we'd love you to come. PLEASE CLICK HERE to early bird price and get more information.
This situation does not look good at all for the badger, there are so many mixed messages and ideas out there about how to deal with the bovine TB problem. Even with all the facts I dont think I could decide what to do never mind letting the people in Westminster decide. The way I see it, the researchers in the field need more time to gather info and trial solutions and it looks like time is one thing there not going to get.
Shame really Badgers are ace animals who've had a very rough ride at the hands of man and it looks like the ride is about to get pretty rough again

Here's anothrer report with a slightly different slant.

In fact, yet another report I read recently suggested animal movements between farms could be one of the major reasons for the spread.
Why is it when we mess up the environment we always hvae to blame somethig other than ourselves, giving us an oppertunity to mess it up all over again !!!???

This from New Scientist...
SEVEN years ago, the UK government set out to answer a seemingly simple question: does culling wild badgers, a protected species thought to be responsible for spreading tuberculosis, prevent the disease spreading to cattle? This week the answer finally arrived. But it was not the simple yes or no answer that most people had hoped for.
In the worst affected regions of the UK, in the south-west of England, bovine TB infects about 10 per cent of the cattle population. Farmers have long blamed badgers for spreading the disease, and a trial was launched in 1998 to find out whether culling could quash it. Since then 11,000 badgers have been killed in 30 trial areas of about 100 square kilometres each.
Christl Donnelly of Imperial College London and her team analysed rates of TB in cattle both inside and beyond the culling zone boundaries. They found that intense "proactive" culling within the zone reduced TB incidence by 19 per cent, but that rates increased by 29 per cent in a 2-kilometre-wide ring around the zone. So reducing TB within the culled zones happens at the expense of previously disease-free farms just outside (Nature, DOI: 10.1038/nature04454).
A second study, led by Rosie Woodroffe of the University of California, Davis, suggests that this may be because the culling pushed badgers outside their usual territories. The team tracked the badgers by placing indigestible colour-coded beads in bait, which allowed them to identify which set a badger was from by examining its faeces.
Woodroffe and her colleagues report online in the Journal of Applied Ecology (DOI: 10.1111/j.1365-2664.2005.01144.x) that the culling disrupted badger territories, making survivors roam much wider than usual and reach farms beyond their usual range.
Taken together, the studies confirm that proactive culling prompts roaming badgers to spread TB beyond the culling zone. "Even with widespread culling, you help some farmers but make things worse for others," says Donnelly. Culling will only work if the culling zones are vastly extended and badgers are prevented from roaming outside them, or if culling takes place right up to a natural border.
The results leave the government with a dilemma. "If they ban culling, they could end up with a serious problem of patchy illegal culling, which would probably make matters worse for local cattle," says Donnelly. "But if they go ahead with culling, some farmers will be unhappy because they're on the periphery."
The Badger Trust conservation group wants the government to shift the focus towards preventing the spread of TB among cattle by improving diagnosis and testing. Its spokesman Trevor Lawson says that since Northern Ireland introduced such measures in November 2004, rates of TB there have fallen by 40 per cent.
