Groups and individuals staging Bonfire Night events in Easy Anglia are being urged by CLA East to not include the release of sky lanterns in their displays.
The organisation, which represents landowners, farmers and rural businesses, is also asking organisers to consider banning lanterns from their venues too, in order to prevent spectators from releasing them.
CLA East Regional Director Ben Underwood said: “While Bonfire Night offers a chance for people to enjoy themselves at one of the many organised displays across the county, we would like them to do this without releasing sky lanterns.
“The fire risk associated with these lanterns is significant, posing a threat to homes, businesses and lives in both urban and rural areas.
“Even after it has finished flaming, the fuel cell of a lantern can register a spot temperature of over 200°C – and even after two minutes it can be around the 100°C mark.
“Lanterns landing or crossing fields can panic livestock, but the biggest concern to farmers is that their animals can suffer a slow, agonising death if they ingest debris from spent lanterns.
“On top of this, they also pose a risk to aviation, and coastal rescue services have been wrongly deployed because lit lanterns have been wrongly identified as distress flares when drifting near the sea.
“The CLA has been campaigning for a total ban for over two years, and will continue to do for the sake of farming, wildlife, the environment, and property owners.”
