An environmental charity is calling for people to help stop plastics reaching the ocean in its Citizen Science Investigations (CSI) Plastic Tracker campaign.

Westcountry Rivers Trust (WRT), which takes care of rivers and their surroundings across the South West, is launching the plastic and litter-focused scheme during the Keep Britain Tidy Great British Spring Clean.

The campaign will feed into the charity’s Citizen Science Investigations scheme, where participants, known as ‘river detectives’, monitor water quality using test apparatus, as well as noting other changes to the river environment such as litter and plastics.

Volunteers are being asked to focus specifically on taking photographs of a river, stream or tributary for evidence of plastic and rubbish such as sanitary products or fly-tipping between the initial dates of April 4 to 7.
