  • Pine plantations provide optimum conditions for natural forests to develop underneath them

    If there is any native forest in the vicinity, tree, fern and herbaceous species typical of these forests penetrate under the pine plantations without any need for action. That way it is possible, to a certain extent, for native forests to be restored, thanks to the process known as ecological succession. This is the conclusion reached by the UPV/EHU’s Landscape, Biodiversity and Ecosystem ...
