Description
Summary:Despite substantial increases in atmospheric pollution and significant correlations between specific inputs and red spruce (Picea rubens Sarg.) decline at certain locations in eastern North America, it has not been possible to demonstrate a consistent relationship between severity of decline and either pollution inputs or climatic factors throughout the region of decline. These results indicate that different pollutants or environmental features may be associated with red spruce deterioration in different regions and raise the question of why red spruce, and not other sympatric species, might be predisposed to injury from a diversity of inputs and over a large geographic area. In this paper we present data to indicate red spruce is a relatively uniform species genetically, and we discuss the possibility that it may be deteriorating because it lacks the genetic flexibility to cope with and respond to abrupt environmental modification.
