Since the summer of 2002, increasing numbers of birch trees (Betula spp.) of various sizes and ages with foliar disorders of unknown origin were discovered throughout Fennoscandia. Symptomatic birches showing vein banding, leaf roll and chlorosis with subsequent necrosis were found from the southern coast of Finland to the conifer tree-line area in northern Finland, in the sub arctic zone of northern Norway as well as in Sweden (Fig. 1). Affected birch species were silver (Betula pendula Roth), pubescent (B. pubescens Ehrh.), mountain (B. pubescens subsp. czerepanovii (Orlova) Hämet-Ahti) and dwarf birch (B. nana L.). Diseased birch trees were either growing alone or in groups. The phenomenon occurred in trees and bushes on mineral sites and peatland, in Cherry leaf roll virus Abundant on Betula pubescens in Finland
