We developed a framework to assess the risk that alien plants in watersheds adjacent to a protected area will invade the protected area along rivers.

Human land uses surrounding protected areas provide propagules for colonization of these areas by non-native species, and corridors between protected-area networks and drainage systems of rivers provide pathways for long-distance dispersal of non-native species.
