Responses of ancient pollarded and pruned oaks to climate and drought: Chronicles from threatened cultural woodlands

Humans have shaped open oak forests for centuries through pollarding and grazing. Nowadays, these cultural landscapes face the abandonment of their traditional uses and new threats, including rising temperatures and increasing drought stress, especially in southern Europe. We need precise data on th...

Nowadays, these cultural landscapes face the abandonment of their traditional uses and new threats, including rising temperatures and increasing drought stress, especially in southern Europe. We need precise data on the long-term radial growth changes of these oak woodlands to better characterize and preserve them. To fill this research gap, we compared the growth patterns and responses to climate variables and a drought index of three traditionally pollarded deciduous oaks (Quercus subpyrenaica, Quercus faginea, Quercus pyrenaica) and one previously pruned, evergreen oak (Quercus ilex) in central and northeastern Spain. In the three deciduous oaks, we reconstructed radial growth suppressions which were mainly attributed to past pollarding events. Recent post-pollarding growth improvement was transitory but long-term growth enhancement could be maintained by periodic pollarding. Formerly pollarded oaks were old reaching maximum ages of 313 years in the case of Q. faginea. Formerly pruned Q. ilex trees were also old reaching ages of at least 384 years. Peaks in major growth suppressions of Q. faginea sites corresponded to periods of intense timber demand following abrupt socioeconomic changes (land tenure and land use changes, local population growth, wars) such as the 1820s, 1840s, 1910s and 1940s. However, other growth suppressions corresponded to dry periods such as the 1870s and 1950s. Oak growth was constrained by warm-dry conditions in spring and by short- to long-term summer droughts (4–18 months). Pollarding abandonment and increased aridification threaten the survival of such old pollarded oak stands that preserve unique cultural, ecological and biological values.This research was funded by Spanish Ministry of Science and Innovation (TED2021-129770B-C21 project).Peer reviewedElsevierMinisterio de Ciencia e Innovación (España)Agencia Estatal de Investigación (España)Camarero, Jesús Julio [0000-0003-2436-2922]Valeriano, Cristina [0000-0001-7687-1417]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242023info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://hdl.handle.net/10261/345069reponame:DIGITAL.CSIC.
