Invasive rushes spreading in upland farm fields

Scientists have used a series of Google Earth images to plot the spread of rushes in farm fields in the West Pennine Moor SSSI — an area of the Lancashire uplands between Bolton, Bury and Darwen. Using more than 200 images from Google Earth taken across a 13-year period between 2005 and 2018, the researchers found that rushes have spread across the surveyed area by between 82 per cent and 174 per cent.
