Project summary

Edit project overview to modify the project summary.

WHIP is a £1.6m project working with 400 farmers across Western Herefordshire to reduce the impact of agriculture on the Wye catchment. Using a bottom up approach, the project starts with the ecology of the rivers and then works with the farmers individually to identify the causes and adapt the management that is causing WFD failure. The project operates on a free and confidential basis, bringing farmers together into groups according to the catchment they are in and annually reviewing progress and monitoring results. This way we transfer 'ownership' of the project to the farmers. We commonly achieve over 95% engagement of the agricultural community in each water body.

The principle issues we are seeking to correct are - Excessive loss of top soil to watercourses. - Excessive loss of phosphate to watercourses. - Pesticide contamination of water. - Excessive overland flow. - Degraded riparian habitat. - Barriers to fish access.

The project delivers land use change by developing pragmatic and effective solutions with the farmers and agri-businesses on a farm by farm basis and delivering them. Fencing works and farm infrastructure works are supported with a delegated grant pool (50% of cost for fencing, up to £15,000 at max 50% for farm infrastructure). In combination we are achieving measurable improvements on a waterbody and catchment scale.

We have developed and adapted Durham University's computer model SCIMAP to create a practical and effective tool that both engages farmers and allows works to be effectively targeted on both a field and subcatchment level.

After a decade of WUF action removing/alleviating obstructions to fish migration in the Wye catchment the last few are being addressed in this project.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

The project is monitoring its progress against the project targets and its effects on the water courses.

Progress to 31st March 2014. Whole project targets in brackets. 223 farmers engaged (400) 176 whole farm plans completed (320) 49 farm infrastructure projects completed (150) 11.7km of riparian fencing erected with alternative stock watering (75km)

The ecological monitoring is in addition to the existing WFD monitoring conducted the EA. Full results are available from the Wye and Usk Foundation.

Headlines - Measurable improvements in phytobenthos communities in catchments with over 80% landowner engagement - 4 water bodies lifted to high status for fish. - Widest ever distribution of Atlantic salmon in Herefordshire was recorded in 2013. Salmon found in Curl and Humber: 2 waterbodies previously too 'silty' to support salmonid spawning.

Lessons learnt

Edit project overview to modify the lessons learnt.

Correcting diffuse pollution is best achieved by working at the appropriate scale (farm by farm) in a catchment context. This delivers real and measurable benefits to WFD status as well as improving farm profitability.

Our revised SCIMAP is proving an invaluable tool in addressing problems of excessive overland flow and top soil loss to water.
