A COUNCIL'S decision to approve plans for new chicken farms has sparked anger, amid fears agricultural pollution is turning the Wye and Severn into “open sewers”.

Forest of Dean councillors have agreed to write to Shropshire Council expressing their opposition.

They raised concerns at their latest full meeting that the Marches local authority continues to approve poultry units close to rivers within the Severn catchment.

More than 50 million chickens are already being farmed at any one time in the Wye and Severn catchments upstream of the Forest, data suggests.

The expansion has been directly linked to the decline of water quality in the Wye.

Chicken manure contains high levels of phosphorus and nitrogen which makes it a great fertiliser for crops.

But with fields already saturated, these nutrients are reaching waterways resulting in excessive growth of algae, starving the river of oxygen and killing fish.

Councillor Andrew McDermid (Green, Lydney East) told the meeting the Forest is already experiencing negative impacts on environment, leisure and tourism.

"As the Forest of Dean is situated downstream between both rivers and next to their outlets into the Severn estuary, it is inevitable that we are adversely affected by any degradation of our river environs upstream,” his motion read, which was backed by a majority of councillors.

The council will now write to the leader of Shropshire Council expressing their “heartfelt” concern.

It will also call on Shropshire Council to fully take on board these downstream impacts when determining any such planning applications.

Councillor Sid Phelps (Green, Lydbrook), who seconded the motion, said the issue is a “not a simple nut to crack”, and expressed frustration over the lack of progress achieved by the Wye catchment nutrient management board, a committee made up of councillors from Powys, Herefordshire, Monmouthshire and the Forest of Dean.

"We’ve not got very far. In fact, the board’s been going for 10 years. It’s got very little progress.

“It really is not a simple nut to crack and more dialogue with more local authorities I don’t think would help.

“It’s not the chicken farms themselves causing the pollution, apart from maybe fugitive emissions that they’re not controlled. Where the problem lies is when it goes off site, it’s spread directly onto farms.

“And I’m not blaming farmers here, they’re perfectly legal in doing what they’re doing as long as it doesn’t exceed crop requirements.

“It’s called diffuse pollution because when the rain falls on it, excessive nutrients in the soil do invariably get washed off, and it’s washed off over a wide area and it’s very difficult to police as a regulator.

“It’s very difficult for farmers to absolutely know, hand on heart, that all the nutrients are going into their crop. This is a really complicated issue”

Cllr McDermid said the Wye pollution is being caused by agricultural runoff from fields with a phosphate nitrate surplus in the soil.

“These rivers are in a mess,” he said. “It’s nearly an open sewer because of agricultural runoff mainly.

“In the case of the Wye, 73 per cent due to agricultural runoff, so it is now classed as unfavorable declining, which is about as bad as it can get.”

Shropshire Council did not respond to a request for comment.
