ResumenCentennial cork oaks (Quercus suber L.) are spread in the sandy soils of Doñana (S. W. Spain). They are remnants from the formerly extended oak forests that were overexploited during the XVII-XX centuries. After the protection of the area as Biological Reserve forty years ago, all silvicultural practices such as cutting, pruning and cork extraction ceased. At the same time, seven species of wading birds began to nest on the centennial oaks located in the marsh edge, forming a big colony. We hypothesize that colonial nesting birds are contributing to the observed rapid oak decline.
