German scientists tested reducing grassland mowing at 45 sites; insect and other invertebrate numbers increased 99% after three years |
German researchers have tested what happens to grassland invertebrates when land use is reduced. The team worked at 45 sites across three regions of Germany, where plots were mown only once a year, late in the growing season, with no fertilisation or grazing. Invertebrate abundance rose by 41% after one year and by 99% after…
