People in South Yorkshire are being encouraged to create their own home-made ponds in a bid to raise awareness about the importance of looking after rivers and wetlands.

Launching the campaign, Sheffield & Rotherham Wildlife Trust warned that local waterways were in “poor ecological and chemical health”, meaning river catchments and neighbouring aquatic habitats had lower biodiversity than they should.

However, “mini ponds” created in as little as an hour could help boost biodiversity, a charity spokesperson said.
