OOS 2 - Alteration of North American forest communities by invasive invertebrates
Ballroom D, Ballroom Level, Cook Convention Center
Organized by: LE Frelich (freli001@umn.edu) and D Foster

This session will provide a survey of invasive insects, earthworms, and slugs that threaten to remove tree species from forests of North America, change community composition by selective herbivory, and re-engineer ecosystems by changing nutrient cycles and seedbed properties, as well as potential policy and management responses.
