 This study examined the incidence, frequency and proportions of non-native species in different land use types across five taxa, ants, birds, mammals, spiders and vascular plants. The results showed that primary vegetation was least affected by non-native species, while high land use intensity was associated with higher incidences and frequencies of non-native species in primary vegetation. This suggests that unused primary vegetation can protect native biodiversity and provide resistance against biological invasions.
