A beast of a clean-up.
Pictures of elephants, sharks, whales and rhinos will be used as part of a campaign against litter in rivers.
The posters show rubbish weighing as much as 30 elephants, 50 rhinos, 27 whales or 66 sharks that has been collected and removed from Tyneside streams, by community clean-ups and councils.
Northumberland Wildlife Trust project officer Jessica Grinsted said: "The message is that a huge amount of waste - more than 500 tonnes last year - ends up in the area's streams and rivers, when a little care can make a huge difference.
"The posters show the council phone numbers people can ring to arrange for large items to be collected in each area, so they don't need to dump their old furniture.
"Even smaller rubbish items can get trapped and cause blockages when other debris builds up behind them, which in turn can lead to floods.
"Keeping streams clear can greatly reduce the risk."
The campaign is part of the Living Waterways Project, a partnership between Northumberland Wildlife Trust, Durham Wildlife Trust and the Environment Agency.
