How does the SCOPS Nematodirus Forecast work?

The forecast predicts the hatch date for nematodirus based on temperature data from 140 weather stations throughout the UK and should be used in combination with your grazing history (more below) to assess the risk of nematodirus infection in your lambs. To use the forecast:-

  1. Zoom in on the map to locate the station(s) closest to your holding. Use knowledge of your farm and the surrounding area to choose the weather station that is most relevant to you. In most cases this will be the nearest station but if, for example, there is a large difference in the height above sea level between your holding and the nearest weather station, then look to see if another station further away may be more representative. (If you click on a station it will give the height above sea level). Alternatively take a view across a combination of stations in your area.
  2. Click on the station(s). Each station has more detailed information on the current risk level, guidance on what to do next, and information on when the forecast was last updated.
  3. Carry out a risk assessment and take action if needed. Click here for more on how to assess risk and what action to take.
  4. Consider additional information to the forecast map. The map above predicts hatch date on temperature data, but the risk will vary from farm-to-farm and from field-to-field. That is why SCOPS provides two tools in addition to the forecast.
