2004
Oszako, T. (Forest Research Institute, Warsaw (Poland))
Oaks are amongst the most important broadleaved trees in European forests, having a multitude of benefits from the highly prizes timber, through the enormus ecological significance of these species, to the great beauty of the tree itself. Decline of oaks has been major difficulty in Europe over many years, although in more recent years, it appears to have significance through the continent. The non-specific nature of the problem makes it dificult to propose absolute methods for its control or management. Although many suspected casual agents have been investigated over the last 20-25 years, no common biotic or abiotic factors has emerged, and the syndrome remains as enigmatic now as it was in the 20th century
