Tree plantations are supposed to help compensate the loss of pristine forest habitats. However, their contribution to biodiversity conservation is limited: For example, plantations host a significantly lower number of beetle species as well as individuals than old-growth forests. This was found by a global analysis published in Forest Ecology and Management and led by the German Centre for Integrative Biodiversity Research (iDiv), Friedrich Schiller University Jena (FSU) and Martin Luther University Halle-Wittenberg (MLU).
