Shoalhaven Riverwatch and Shoalhaven Landcare Association have staged a roadside flashmob clean-up of escaped silage plastic.
In two hours, nine volunteers collected more than 60kg of plastic along Wharf Road just out of Berry and the Jennings Lane, Bolong Road area.
Clean-up coordinator Ev Pettigrew said everyone can make a difference.
"We can all make a difference cleaning up the plastic caught on fences or in ditches," she said.
"It is the plastic we don't see that ends up in our waterways and oceans or is trodden into pasture which is of greater concern.
"With the strong winds we have been experiencing the wrap can be picked up and blown for kilometres."
She said Landcare would be working with farmers to improve retention of this waste on the properties and hopefully re-establish a recycling option which has operated in the Kiama and Shoalhaven LGA in the past.
She said in the meantime, all Shoalhaven Waste Depots receive silage plastic waste into their landfill free of charge.
"Anyone walking or cycling our country roads can assist by collecting these stray bits from the fences or ditches," Ms Pettigrew said.
