Dense crowns of trees are a buffer, a 'time capsule' protecting against the effects of rapid climate change. But when they become less dense, for example due to mass felling or tree diseases, the conditions at the forest floor dramatically change and threaten the species that live there. These are the conclusions from a study published in 'Science', in which Polish researchers took part.
