The Enemy Release Hypothesis (sensu Elton) is one of the key hypotheses explaining the success of invasive species. If invasives commonly escape their enemies and if this enemy release is responsible for their dominance over natives, then excluding enemies may help level the playing field and increase native plant abundance. We established long-term enemy exclosures in swamps, old fields, forests, and restored grasslands to test how enemies influence the relative abundance of native vs. exotic plant species.Many of these exclosures were constructed in public areas and Dave Williams (Lawton High School) is currently developing signage and activities for citizen scientists of all ages to engage in their own data collection on a subset of our plots.
