  • The researchers say their findings on UK biodiversity between 1970 and 2015, published in Nature Ecology & Evolution, may provide evidence that efforts to improve air and water quality could be paying off.
  • Among the four major groups studied, only one of them — terrestrial non-insect invertebrates (mainly spiders, centipedes and millipedes) — exhibited an overall trend of declining distribution (by 7% since 1970).
  • Mosses and lichens have also increased in average occupancy (distribution) by 36%, while terrestrial insects, such as ants and moths, exhibited a slight increase.
