Nature is intimately connected with human well-being of current and future generations – which is why an array of reports track the state of biodiversity and predict the impact of our way of life on its evolution. These reports are based on several indicators that only take indigenous – i.e. “original” – species into account for each region. Yet today modern environments are made up of indigenous and introduced species. The introductions are either deliberate – as is the case, for example, with agricultural crops – or accidental, as was the case with the Asian hornet or the box tree moth. Although these introduced species play important roles, they are ignored by specialists, a fact that partly distorts the international nature reports. The study by the University of Geneva (UNIGE), published in the journal PLOS Biology, recommends that the positive and negative contributions made by these species should be included so that the public has an accurate view over the surrounding nature and its evolution.
