Diseases of Forest Trees : Consequences of Exotic Ecosystems ?

  title={Diseases of Forest Trees : Consequences of Exotic Ecosystems ?},
  author={William J. Otrosina},
MUCh attention is now given to risks and impacts of exotic pest introductions in forest ecosystems. This concern is for good reason because, once introduced, an exotic pathogen or insect encounters little resistance in the native plant population and can produce catastrophic losses in relatively short periods of time. Most native fungal pathogens of forest trees have co-evolved for eons with their hosts and have reached a sort of balance between them and populations of susceptible tree species… CONTINUE READING
