Abstract

Tree decline has been reported from several locations in North America in recent decades. The decline is widespread in areas remote from the classical point sources of air pollution. This paper describes the geographic and spatial extent of the decline, the symptomatology of affected trees, and the known and possible causes. In addition, a few case histories of tree decline in the vicinity of sulphur dioxide and fluoride emitting sources are described.
