Are plant communities on the Canary Islands resistant to plant invasion?

Oceanic islands are renowned for their unique flora and high levels of endemism. Native island plants, however, imperilled by non-native species that can become invasive outcompeting natives. The threat native assemblages generally increases with isolation the number endemics featured, but also human-associated disturbance land use. Based on this, Canary Island plant systems should be highly threatened invasives, similar to other oceanic globally. However, Canarian only weakly infiltrated rarely directly plants. Further, disturbed areas, usually among first colonized invasives islands, recolonized here we postulate four hypotheses (climatic filter, well-preservation status, human legacy permanent colonization) explaining this unusual behaviour Islands, providing an opportunity understand drivers processes behind invasion into communities islands.
