RT Journal Article SR Electronic T1 Oak Decline in Austria and Europe JF Arboriculture & Urban Forestry (AUF) JO JOA FD International Society of Arboriculture SP 71 OP 73 DO 10.48044/jauf.1993.013 VO 19 IS 2 A1 Christian Tomiczek YR 1993 UL http://auf.isa-arbor.com/content/19/2/71.abstract AB Oak decline has been reported periodically in Europe. In most cases it has been caused by a complex of abiotic and biotic factors. At present it is decreasing in Austria and in many other European countries. The most recent oak decline differs from former oak decline problems mainly because of its enormous extent, which reaches from England in the west to the Ukraine in the east and from Sweden in the north to Italy in the south and affects a high percentage of natural white oak stands.
