The Country Land and Business Association are arguing against the government's decision to not ban sky lanterns.
The government's decision was based on a report by the agriculture agency ADAS, however the Association said the decision failed to recognised the scale of threat posed by the fad.
The Association said the report - entitled 'Sky lanterns and helium balloons: an assessment of impacts on livestock and the environment' - was "inconclusive and unsatisfactory".
CLA Regional Director Robin Edwards said:
“Defra is under the impression that the main risk posed by sky lanterns is to aircraft. In fact there is plenty of evidence these flying bonfires are damaging property and crops and harming and killing cattle."
"Even the ADAS report concluded that ‘the fire risk associated with the use of sky lanterns is significant’, reported around 16 cases of injury or death to cattle, sheep or horses and admitted there may be a ‘significant level of under-reporting by veterinary surgeons and others".
