Research published in the scientific journal Ecosistemas de la Asociación Española de Ecología Terrestre shows that temperate forests that have been conserved for more than 100 years after suffering centuries of human activity have not yet been fully recovered, a longer period than previously estimated. In the words of the authors of this study, “at first sight a forest that has many trees and other plants may seem recovered, but in addition to that, the trees, fungi and other species present must interact and this may even require centuries“.
