Agent Impact

Impact: Heavy
Geographic Scale of impact: Widespread throughout range
Impact Notes: Prior to accidental introduction, had been candidate for introduction and study. Reduces mistflower perctentage cover 5-fold with a corresponding increase by more than 60% of the percentage cover of other plant species. Increases native plant richness in NSW and QLD. Most effective in shady areas.
