GM crops get police protection
Protesters want to destroy current GM crop trials
Security has been tightened around the UK's four remaining farm trials of GM crops amid fears they will be targeted by protesters.
A group of 28 protesters, including Greenpeace chief Lord Melchett, were charged after an alleged attack on a trial farm in Norfolk on Monday. All have now been released on bail.
But the worry for scientists running the trials is that the remaining sites could also be destroyed. Protesters have said GM crops are contaminating the environment and are legitimate targets.
Scientists fear that test fields in Redbourn, Hertfordshire, could be the next target.
Roger Turner is chairman of the Supply Chain Initiative on Modified Agricultural Crops (SCIMAC), a consortium for the agriculture industry. He is concerned for the welfare of the existing sites.
"The farms need extra protection," he told BBC News Online.
"Police security in the test areas is on a much greater state of alert and vigilance, and there are now police cars stationed there."
He stressed the importance of the trials, saying the UK "led the way" in Europe for GM research.
"Now protesters want to destroy them - they are acting undemocratically. It is very sad and lamentable".
As to whether the tests will suffer, with almost half their crops destroyed, scientists appear to be divided.
A spokesman for campaign group the Genetic Engineering Network said on Tuesday that the whole experiment in Norfolk had been "completely invalidated by the destruction carried out by activists".
Results 'not affected'
But one of the scientists assessing the trial results said "all is not lost", and that even the destroyed sites could still render information.
Dr Les Firbank, of the Institute for Terrestrial Ecology, in Cumbria, told BBC News Online: "Of course we will now rely more heavily on the remaining sites, but we can still monitor the sites targeted by protesters.
"In fact, we'd already had a lot of data from the Oxford site that was damaged last week."
Dr Firbank said the main job of the test sites was to learn the "methodology" for how best to assess GM crops in the future, as well as studying biodiversity.
"They're about what and when to measure," he said. "This year's results won't affect the overall results anyway."
His main concern was for the farmers, who he said had suffered "intimidation from protesters, which is totally unacceptable". He would not reveal the farmers' identities, saying they were already under enough pressure.
But he stressed that the tests were in the public interest because "we are independently evaluating the impact of GM crops, and simply providing people with important information".
