Managing multi‐species plant invasions when interactions influence their impact

Invasions by multiple non-native plant species are common, but management programs often prioritize control of individual that expected to have the highest impacts. Multi-species invasions could larger or smaller impacts than single-species depending on how co-occurring invaders interact alter their abundance per capita Synergistic interactions, such as facilitation, may lead greater combined However, if focuses a single invader, suppressive interactions produce unintended consequences, release invader with stronger impact. The mechanisms described here highlight where better evidence is needed predict and which mitigation strategies most effective. Focused research required provide evidence, can aid managers in prioritizing target determining best sequence removal – one minimizes detrimental communities ecosystems.
